Re: [RCSE] 12V Bench Power Supply
You may not have a big enough load on the 5v supply. Sounds dumb. All regulation is done on the 5v supply and if you do not draw enough current on the 5v supply it will probably shut down. And all you wanted was 12v. Rick Richard Hallett Pittsfield ME Dan Kitching wrote: I'm using a converted ATX power supply as well and it's great, with one exception. My Orbit Pro charger has a power switch, and when I turn it on the power supply shuts down. I've never opened it up, but imagine it might have a largish capacitor that sucks a largish amount of current when first turned on. Maybe the power supply sees this current and shuts off to protect itself. Weird, but my other chargers, including a GP Triton work great on this power supply. Dan David Register wrote: A newbie here in town borrowed one of my converted PC power supplies for charging his electric and then started looking for a new PC supply of his own. He found a really good deal which I've converted and it works very well. In our area, used PC supplies are getting harder to find (for free) and it pains me to pay $20 for a used supply. This conversion is very easy (see Red's Battery Clinic article at http://www.rcbatteryclinic.com/) and follows the ATX conversion with the exception that you only need to ground the PS-On wire to make the supply work properly. No need for the 'Power Good' line. On this one the PS-On wire was green on the motherboard connector but it's clearly marked on the circuit board inside the case. Supply is a 250W unit from Tiger Direct. Cost is $15 +S/H. Add a couple of bucks and a little sawing on the case to fit a banana plug receptacle, clip and shield a few wires and you're done. I've been running this one for a few days on GP, Sirius AstroFlight and FMA chargers for NICd, NiMH and LiPos (Tx, Rx and motor packs) with no problems. Haven't pushed current too hard (couple of amps) but the supply is rated for 10A so it will probably deliver 8 or so. Just FYI for those looking for an easy way to get 12V bench power for your field chargers. - Dave R RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] CF on spruce spars
The carbon is by far superior. The carbon goes on the outside. The further to the outside the better.

Re: [RCSE] Buying batteries
I go to WalMart and buy the newest high capacity AA cells that they are offering. I have always found that the first charging has to be slow but after that I recharge at 1 amp. I am using these in a 6 servo glider and have found that I usually use about 600 ma during an evening of flying. The Rx drain fairly closely matches the Tx drain of the Evo. This of course only answers half your question since you wanted cells for smaller planes too.

Re: [RCSE] OVSS and Line Breaks
Maybe we are getting to that point that we are going to have to define winch as was done in F3B. Other countries did not have the Ford starter so went with individual winches rather than club winches but now we have a definition for that winch 23 milliohms of resistance between the starter and battery. We are now pushing for an unbreakable line but now have models that can break most reasonable line. I find it rather absurd though that now we are spending more energy lifting the line rather than the plane. So why are clubs sticking with the Ford longshaft convenience? I am surprised that some club has not come up with an alternative using diesel starting motors. Or are we someway saying this is enough. I doubt that we have the courage to drop back to the quarter power of the F3B winch. It depends on all kinds of wrong things. Own my own winch? you must be crazy? Walk to retrieve? I am too old. Those are a few starters. A conundrum? Rick Richard Hallett Pittsfield ME [EMAIL PROTECTED] wrote: Tom's analysis is, as they might say in JOE (jolly olde England), SPOT ON. And this excellent observation from non other than our current LSF President. Tom has the experience to define the FIX for this issue and has just done so. I'll back his direction on this one. Regards, Dave Corven. AMA 878 LSF 254 I've followed this thread with some interest ... as JB said, we've discussed this topic trekking back and forth from many contests in the van. The advent of affordable molded models has done more to cause line problems than any other single facet of our chosen sport. Today's molded sailplanes are so strong that they can easily part 200# test winch line, almost at will. This is the primary reason we in the OVSS and AMA/LSF Nats have moved to the 290# test lines we use today. If there are no burns, abrasions, crappy knots, etc. it's unlikely that you will be able to break the line on purpose without damaging the model. With aircraft of this magnitude of strength, the need for developing good winch technique has fallen by the wayside. In my early days in the sport, everyone flew open framework gasbags and a full pedal launch on our SIX volt winches would result in a Monokoted bag full of sticks. You learned to temper your foot or you learned to rebuild - fast! Today's competition pilot doesn't need to develop any such technique, he can simply hook up, step on the pedal and GO! Poor winch technique is easy to spot, the smoke coming from the winch armature and excessive wing flex are sure indicators. Moderating the amount of energy in the line, motor and wings are all a part of launching technique that is all too lacking among many competition pilots who have skipped the early learning curves of winching built-up, more fragile models. Examination of the line break often yields the answer to why the line parted, the aforementioned abrasions, poor knots, frozen turnaround pulleys ... equipment failures should result in a relight. The pilot that breaks the line as they push over into the zoom has no call for a relight, he got 90+% of the way up. The pilot who full pedal launches through a thermal on tow shouldn't get a relight, either, unless the equipment failed (and if he had proper technique, the line likely would have stayed intact). Weak links ... tried in F3B a decade or more ago, the weak link was dropped quickly because the relative weakness of the link was actually seen to be a safety hazard as most links failed just out of the launcher's hand. Yes, the (rather large) relative difference between the line and the link had much to do with the problem, but what is the right differential? For a 100 RES or NOS vs a 3.9 meter Sharon? Do we need devices on the winches to set torque or tension limits? Same issue as the weak link ... what's the right amount of torque and is it the same for every model? A seasoned pilot acting as the Launch Master can readily evaluate each launch and come to a likely first approximation as to cause for line failure on the spot ... subsequent investigation at the point of failure serves to validate whether the call was correct or not. I would guess that the Launch Master is going to be right the majority of the time. Reserve one or two winches on the line for relights ... pilot calls the break, Launch Master either denies the relight request and the pilot continues the flight or confirms the relight and the pilot comes down IMMEDIATELY for relaunch. If the number of breaks exceeds the number of backup winches, call the group down and start over. I suggest if that many lines break in the same round there are either equipment issues or you're winching over desert scrub or through rose bushes. Rather than look for a technological silver bullet, I propose that we, as a part of bringing newer flyers into the competition circuit, teach winch technique alongside air reading skills and spot landing practice. It will improve

Though I've not yet developed an allergy to it yet, any serious sanding session will find me with a ring around my nose and mouth when I'm done.

They usually double stack a chem absorber and the dust cartridge. Make sure the seal is pretty good by putting your hands over the ends to block the air and see if you can pull a reasonable vacuum inside. Tighten, adjust or replace if you can't get a good fit. Not all masks fit all people and they come in different sizes. Mine leaks a bit by my nose, so I have to adjust it a little lower than what the natural wear position would be (maybe it would be easier to get the nose adjusted - nah). Dust off in the workshop if you can. The dust settles pretty quick when using coarse paper, but don't be afraid to leave the mask on until the outer layer of clothing is off. Oh and vacuum the shop before starting the covering (I hated adding that part). Hopefully the eye exposure doesn't cause any problems.

[RCSE] SNOW/ planes for sale
Yes that four letter word. Well most of the parts have arrived for my 4th CNC machine. So it is time now to think of building at least during the week. Perhaps someone in a warmer section could benefit I finished off my fourteenth Bubble Dancer and have been flying it the longest of any that I have built.I had flutter problems with the previous two by allowing the stab mount to have a loose hinge. With this one I got rid of the problem. Phew!!! Unfortunately when I launched it I knew it was not quite as strong. After some research I found the green Amoco foam was no longer made by Amoco and the 45 # compression had now dropped back to 25. It will still take a very powerful launch from most winches. So now it is time to build another with Dow hi load 60. The unit is covered with glass only no paint so the carbon is very visible. It is equipped with 2 metal gear Hitec 85, no spoilers and an FMA M5 (ch11) receiver and a high capacity battery. Flying weight is approximately 39 ounces. The foils are the AG24,25,26 that Mark designed specifically for the application and in the write up has my name on them. Sale price $550 plus shipping. It will be ready to fly when you receive it. The other plane that I was trying to wring out the flutter was a Supra clone. Again the fault proved to be the same. It seems to be standing up well to my F3B winch. In order to iron out the difficulty though I switched to a thicker wing the SD7084 that Donovan of Selig Donovan said could race with the RG 15 at a slightly heavier loading. The interesting facet I find with this model is similar to my use of it years ago in the Magic by Weston it can pirouette on flaps in lift unlike others that I have flown. The planform is similar to the Aegea with the forward sweep of the Supra. A case of making good use of your mylar. The unit is equipped with four digital thin wing servos by Hitec and a Multiplex micro digital for the elevator an d a Futaba 133 for the rudder. All up weight 75 ounces. The receiver is a Multiplex IPD on 51 driven by a high capacity battery. The top surface of the wing is white with a pink tip diagonal . Of course this flies more like one of Harley's. So now having gotten rid of the flutter it is time to build it with Mark's thin foils again. Sale price complete ready to fly the day it lands $750 plus shipping . Finally I have a 3m Laser with Multiplex digital servos in the wing and JR 341 for the stab and rudder. A new high capacity battery drives the Airtronics FM receiver. The Fuselage is natural Kevlar with white wings on the top and carbon black on the bottom. The fuselage was crashed once and excellently repaired. Sale price $700 plus shipping. I received this in exchange for assisting in programming an Evo. Because of this the servo assignment is the Jr order for all of the above. So if you are in the same boat I will sell an Evo(Synthesized) to go with any of the above. I have one Evo 9 $500 and an Evo 12 $600. You would primarily buy them at this price because you are interested in the fact they are preprogrammed. The Evo is one of the easiest radios to program but almost impossible because of our previous experience. It is that experience of flying a plane towards you for the first time. Ask for pictures.

At 07:37 PM 10/2/2004 -0400, you wrote: 3rd best ascending score. with a mandatory landing circle. Fly any time till the closing moment. This is very similar to the HLG 15 second increment type contest in which you keep trying till you are up to the next increment with the exception that here no one tells you where to start nor how big the increment and the two ends are floating all day. The score sheet is a large piece of plastic near the launch point. Consequently when you come enter your score you can see all the others but you would have to calculate how they were doing by running back through their scores. Usually someone is already standing there doing the same. Ascending is in time. No scores are thrown out. As time has gone on the strategy of serious pilots is changing. So now you purposefully put in a few moderate scores attempting to make them grow. Then all day you try to continue to make them grow. At the end of the day we all go back through all the scores and pick out the numbers to give us the third best ascending. Knowing how it went last year I flew a 621 on my first flight followed later by a 628 but could never get higher so had to fall back on all the low scores that I had made in attempting to get something over the 628. I was sure I would easily be beaten if I did not have a moderate ten minute flight for the beginning of the run. Scores posted 621,171,207,247,216,125,668,140,461. So my ending score was 207. New pilot had the following string 10,114,90,91,65,80,111,104. His third best ascending score was 90. Of course you know what happened. The weather changed and a few generous cycles of lift went through but not good enough when I needed it with my moderate skill. Photo of scoring panel is posted on the club site http://archive.downeastsoaring.org/td050104/score.jpg When the thermals came through many people were able to jump on it because they had their launch system ready. The rest of the time we had a slow relaxed contest with no pressure chasing timers or slots. Most contestants flew more in the contest than they would normally all month. This fall we are adding a mandatory landing. You must be in the circle to claim the score. Now if you were perfect you would add the hours from 10.00 till 3.00 in the afternoon and set yourself up for three flights and throw out 30 minutes. That would give you 3.5 hours. So fly the first time for 65 minutes. The second time for 70 . Then your final for 75. Giving you scores of 3900, 4200, and 4500 with a winning score of 3900 but will the weather cooperate?

Re: [RCSE] Dyneema, Spectra
Good leading edge material but very hard to cut. Easiest cutting was with a soldering iron. Then in today's thin layers you would probably be left with a bump. After I stopped using it I found I should have been cutting all the fabrics at 45 then I probably would have felt differently about some of the difficult fabrics.

[RCSE] 35 ounces/ wind
Bubble Dancer dances at 32 till about 38 then you begin to lose the Dance. The plan is to make a very low drag plane. The foils are high speed very thin but to make them work in the application very light. Aim to get the lightness so you can enjoy the benefits of the high speed foil. Kind of your cake and eat it too The response is much different to ballast compared to a draggy foil. Ballast picks you up real quick I build them very light like this to enjoy in the evening at Sundown after work.

[RCSE] Highstart Max Launch
The ping. As the wind goes down you need a stronger hi start. Conversely as the wind goes up you need less. Wind is required but usually not much. As you launch your glider at about a hundred feet you go sideways then after that direction you reverse and in the back and forth pattern attempt to stretch the line as you slowly climb. In favorable conditions it is possible to reach a thousand feet before coming off the hi start. The chute will bang when it opens just like full sclale. Unfortuinately you had better have a spar that can support it. As a result I have always considered any contest with a hi start rather ridiculaous because it boils down to the same thing - launch skill. I do not see anything simple about it. I used to carry three to match the days conditions. Rick RCSE-List facilities provided by Model Airplane News.

RE: [RCSE] New Shop
In my shop I have a twelve foot by 16 inch glass table on an old straight medium duty extension ladder. This is supported by steel stools on the concrete floor. All cutting and setting of wings are done on this table. This table is set up as a zone off the boiler with output temperature set for a cut at 140'. I do not walk behind it. In addition I have a 30x60 inch table set in the room paralleling the glass table. This table is set to walk around it. I aim shortly to pick up my piece of glass that will make this table a glass table too.The other major piece is the vacuum pump. The radial arm saw and bandsaw are in the cold area on top of the garage. I use the radial arm saw for finishing edges that need to be joined after they are bagged. I find I can get pretty good precision with this. Truthfully there is no need to own this tool if someone you know has one near you and would allow you to install your blade on their saw. I have to go next door for the air compressor The air compressor is used to get the dust all the composite wings to get the last gram of weight off them. It proved very valuable in helping to knock the last few grams off the components to meet the Bubble Dancer challenge - 32 ounces. I have shelves and tool boxes with many other tools that are occasionally used. I have a large fishing tackle box for small parts I have other places to do heavy work and brazing. So basically my shop consists of two glass tables with one heated and a vacuum pump. You have probably guessed that I do everything in glass and carbon. With balsa I will hack for days. New foam stands behind the glass table lengthwise leaning against the wall. Small tools are kept in several tool boxes. I really felt stupid afterwards when someone asked to see my workshop and all there is - two empty tables I am notorious for giving everything away to have a fresh start. But I am very sneaky about this. You give away planes to people that you will see using them. Sometimes it gets embarrassing when someone flies your old plane better than you did. Most of the time though you can evaluate your new production by letting the same people fly them and quietly looking at your watch. The phrase I used to describe the situation is to say that it is politically expedient to keep a low profile All the nice toys tools and planes in the same place can get you in trouble. Theft, insurance, your wife. I need to get that central vac though that Bill has in his list but I will leave the rest scattered over the premises. In addition I am still trying to figure how I am going to finagle a cnc foam cutter into this situation to keep it low key Rick Date: Mon, 30 Sep 2002 14:00:38 -0700 From: Bill Swingle [EMAIL PROTECTED] To: Robert Bingham [EMAIL PROTECTED], rcse [EMAIL PROTECTED] Subject: RE: [RCSE] New Shop Message-ID: [EMAIL PROTECTED] In order: Band Saw Belt Sander Drill Press Good Bench Vise Central Vac Grinder Dremel Air Compressor Bill Swingle Janesville, CA [EMAIL PROTECTED] RCSE-List facilities provided by Model Airplane News.

[RCSE] Rahm retriever
Twist. Back to back spinners with two rings between will just about eliminate the problem. If not find out which end of the spinners is restricting movement. At that end put two more rings.The rings act as the universal joint to free up the spinners to spin. If the spinners are too light I have heard this can cause problems. Further you may have to do some work on your winch line too with double swivels in exactly the same way. It is assumed you are using braided nylon or Dacron for the retriever and braided nylon for the winch . Twisted line simply causes too many difficulties since you are always trying to unwind the twist Speed The Rahm was supposed to have used a 6volt motor. You could sub a 12 or 24 armature cut to length to slow it down. The cheap way out is to use a piece of heavy coat hanger between the relay and the starter. Protect it because it can glow red hot but usually will perform the function well for you. I have also used 3/32 stainless welding rod.

[RCSE] RDS DS
Harley I am basically lazy. The best reason for using RADS at the slope is to preserve the servos. Very little movement is typically needed. So here is the lazy man's way to do it. Apologies but to understand this you have to understand the RADS system first off Harley's site. That being the case (limited throw requirement) completely make the wing as normal (foam and glass not EPP) but with the trailing edge made with the rest of the wing. Cast a small slug at the hinge line going from one skin to the other with epoxy and West Systems light filler or something similar where you want the hinge bearing to be in the wing and the slot in the aileron. Make this as one slug of epoxy and filler by cutting out the foam after the glassing has been completed and fill it in with the epoxy filler slurry... Of course you would put it in from the bottom for looks. When you have determined where the drive should go drill through the slug vertically with a small drill (large enough to cut through and still be seen) for a marker on the hinge line. Now bandsaw the hinge line and finish it to your hearts content. Drill the hole towards the servo slot using the marker as your precision entry point.. Use a piece of wire through that and use your wire cutter current to make a cone from there to the servo (you have already cut the servo pocket). In the opposite direction you only need to take the dremel tool and make a slightly wider horizontal hole (for the pocket) with the drill of the size you are using for the drive at the same marker that you made originally.. Don't forget to make your holes as the instructions suggest in relation to the type of service. Now this will not work for flaps but is terrific for the limited throw of most ailerons. You have just created your pocket in the aileron and excellent bearing in the wing and a cone slot to get to the servo. Now carry on by bending your wire and sizing it to fit to the servo with the RADS driver already installed. Now my question Harley. Is there a source for buying the normal RADS bulk. 50-100 at a time Rick RCSE-List facilities provided by Model Airplane News. Send subscribe and unsubscribe requests to [EMAIL PROTECTED]
[RCSE] still-air times
I was very pleased to be able to get 6 minutes in dead air time. Thought I was doing well. Launch could only safely produce a moderate zoom though. Conditions several nights in a row. Dead air, never a twitch. To get the six minutes I still had to turn with trims only otherwise I would only get five minutes. Interesting to note I frequently did better this way than nights with the little bits of lift I have read of the attempt to produce planes like this but decided that I lived only in sink. I have seen Dennis Phelan and one of his friends though produce launches that looked to be double the height with their F3B models . At those heights I would not be suprised at the times Mike records Very interesting. Rick Date: Fri, 4 Jan 2002 08:01:06 -0800 (PST) From: tony estep [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: Re: How long is yours? Message-ID: [EMAIL PROTECTED] Re still-air times: Suppose that you can launch to 600 feet (pretty good for still air with a 600 foot line). If your plane's loading is 9 oz/sq ft, at a CL of 0.9 it will fly 23 ft/sec. Therefore if the L/D at that speed is 23 the sink rate will be 1 ft/sec. That's 10:00 from 600 feet. BUT -- there are a lot of moving parts in this test. It's hard to get consistent flights with the same launch height and to keep the plane flying at minimum sink throughout the flight. And of course it doesn't take much air movement to change the results dramatically. If the air is rising at even 10 ft/min, you'll stay up 12 minutes instead of 10! This sort of air movement is easily possible even after dark. So it's mighty hard to be sure you're drawing the right conclusions about a plane's performance from still-air testing.

[RCSE] Finishing a glass wing??
I was complaining about the non stiffness of my ailerons and asked what could be done about it. I received a reply from the famous or notorious Sal. His response was to finish off those two exposed surfaces and gain a lot in stiffness. He was right. Finishing off that foam does matter. Thankyou again Sal. I simply paint on a layer of West system epoxy then lay on a much wider layer of glass in about 2 ounce. Then I put enough more of epoxy on the surface of the new layer of glass to make sure it is filled at the edges. When it is dry you should have produced a slight bump at each of the two edges of the narrow strip which you can sand from the top and bottom then lightly on the exposed side you had before. This is a very easy finish and produces great results. I normally in addition trying to get the best of both worlds cut this glass at 45 degrees. But this makes the handling while doing the job quite difficult so be patient. Put on the other way the grain probably would end up in the wrong place. The results are strong enough to use poly tape and pull pull on the rudder without it crushing inwards. The stiffness gain on the ailrerons is impressive. The same technique is used for finishing the exposed ends of wings where they butt together. The finish is put on after the joiner is completed. The joiner is inserted with a casting of West System epoxy and light filler as follows for the hardpoints. Now that this edge is finished I cut out the hole area for the hardpoints. Cut from one surface down just to the other area. Then pick out the foam like a dentist doing a good undercutting job. When you are finished; fill with West System finishing epoxy filled with their lightest filler. I usually try to undercut the hole so that it extends against the new surface you have just created. You probably should think in terms of about a three eighths inch cutout extended under the surface to about half or more. After doing this a few times I discovered in some kit reviews in QFI that some manufacturers were beginning to do it this way. Rick PS Like many others I have gotten in the bad habit of replying privately. So how would the rest of you do it differently??.

[RCSE] foam
My foam supplier tells me that Dow grayboard is no different than Owens corning Foamular 150. The tow sure feel and look different to me. What is the deal? Mike in Arcata Mike I personally did not like pink. I always considered it soft to the touch. Then I met gray but that also is the same. The gray was slightly lighter in weight than the normal blue. But the gray also was much easier to dent. The normal green was harder than the blue. All this gets technically non difficult if you knew the pressure under which it was formed. I have used blue formed at 25 but I think gray was 15 or 20. For small pieces and very thin I have used the "hi load 40". Depending where you live and the purpose of use the standard for you in blue could be anything from 15-30. I think most of us see 25. This is pounds per cubic foot. You have to take your calculator and scales with you . This is assuming that as it is made under higher pressure the weight somewhat follows the pressure. Bottom line for the layman is weigh it then you will be much closer in your comparison. RCSE-List facilities provided by Model Airplane News.

[RCSE] foam
Since foam comes in various colors and densities use the two properties to color the wing. It is a thought but you may not like what you see underneath but it all disappears at launch height anyway. The question that is important is what I can see in the air not on the ground. Unfortunately that usually means white top and black or dark bottom. Somewhere you are going to add weight to make the color. I have taking the lazy way out by adding no color on the top and just as I finish I lay black tissue on the lay-up just as I close the sandwich before putting it in the bag. This only goes on the bottom of the mid sections of the three piece panels I did see a wing with just the glass on it with pink foam. Looked real good. Just a suggestion.

[RCSE] creating a wingrod tunnel in foam?
The scrollsander page has some fantastic pictures of how to do it. Again like others I have been doing it this way for years. MY WRINKLE. I do not use an exotic supply. I take the present transformer used for normal cutting and add about six to ten turns of #17 or #18 magnet wire to give me the low volt heavy amps I need for this cutter. This idea will only help a few for the rest a long explanation probably will be necessary. I suppose that would make this idea exotic for many. My present cutting supply is a new battery charger adapted for the purpose. In addition I save my MacDonald straws for the wire tunnels. Nothing like light spackle for correcting all the mistakes. Oh yes in answer to one question you have to know through expertise that any wire not in the cut is going to turn red hot and cut by radiant heat rather than contact. This means that the form has to make all the wire contact almost all the time or you must lower your temperature drastically. Rick RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] Gas Powered Winches?
I gave away the large Sears deep cycle battery I used for the May contest. It was too heavy for my back to handle. Same for the Ford winch. So I dropped back to a small Lucas 35 starter and a Bosch permanent magnet starter. To get good launches I use the very stretchy Advantage 130 line. I use a better garden tractor battery with it.. Next May I will buy another battery to go with the Ford long shaft winch with "real balls" for the contest then give the battery away at the end. As a kid I destroyed my ability to throw anything overhand so have never attempted hand launch. The knees are pretty stale at this point too. The gas powered winch not generator was published before 1980 in RCM but they did not include any information on the individual pages so I have the article but do not remember exactly when He also did a small electric according to the article in 2/77 The gas is based on a Poulan chain saw. finished weight was 12#.

The original author of this string had an excellent point.
From the recommendation of the original presentation by Selig and Donovan at
the appropriate MARCS symposium. I have used the SD7084 for years with
excellent results.
Besides being an excellent airfoil second to very very few it is "do-able".
Flat bottom, easily out thermals most, races with the RG15, good stall
characteristics and many other good qualities
That alone("do-able") recommends it as an excellent starting point. After
reading the article though you may stay there for the 2m and up classes.

[RCSE] coreless
The FMA website http://www.fmadirect.com is the easiest site to get to that lists a coreless servo. The prime difference is the quality and type of the motor. In addition the gear system is normally of the higher quality. The problem is their size. I have not had the chance to examine any of their coreless servos. With there better parts being the top of the manufacturers lines of course they will center better. So if you were only to buy one it might be worth it just for the elevator. The Horizon listing of servos is much harder to get to and does not list which ones are coreless in the list that I viewed. Their easiest list to read is their former "Indy" ad or catalog division of Horizon in AMA. Unfortunately the AMA magazine is available to probably less than half the list. In addition they don't always include the list. Everyone else has decided the standard case is .812 inches wide but JR is .75 wide. The JR will do flaps on many wings with a standard case. The standard case gives about twelve options of which there are several coreless and beyond that several digital. The coreless JR are very smooth running. The average person will be very surprised when they attempt to move the top of the servo and discover how easily it turns and smoothly. I have not had the opportunity to try the FMA this way. I had one friend who flew helicopter. Basically you had to have at least ball bearings and often beyond that coreless for the desired performance. But when it came to contest days for other types - he was both a very good flyer but an excellent builder- he would use bottom of the line Jr which was at that time the 507. His logic- he needed the servo to last three trim flights a half dozen practice flights and then three or four contest flights then he would sell it. He felt that would last long enough for him to do that but it would take a little more and you could tell they were deteriorating. His advice on gliders was to give the elevator a blip in either the up or down direction your choice before launching but always the same direction. This was to test for radio on and set the elevator to the same position each time for launch. This took care of many of the non centering and similar problems that we often see. So the coreless if you can find one that will fit in the application:: because they are ball bearing , better gears, and coreless motor would easily outlast the common servo. But wouldn't you expect that at 3xs the price. Now the question is will it improve it enough to make it worthwhile? Or will I keep it long enough to make it worthwhile?

Re: [RCSE] Radio Problems-need a source of choke
The most important change for the glitching at the back of the vtail was not touched by chokes and capacitors. I had also done the flaps and ailerons the same way really compounding the problem.. I was using #26 computer cable wire and using just four wires. When I used separate wires for each servo, since I did not have any larger wire with a thin enough insulation cover, the beads and capacitors could clean up the act and in fact were hardly needed. So much so that I am still looking for a good source of wire in the next two sizes commonly used 24 and 22. I should credit someone for writing a note to me about this but I have forgotten but would like to pass on their tip to me that worked.

It's easier, and subjects the fragile crystals to less banging about.The really important factor is when you go to an impounded fly in, you will most likely have the right channel number on your module. If you forget, and the impound guy or gal doesn't make you pull your radio apart to check then it is up to your good memory what channel your on.

It operates as a tuned entity. If you are flying valuble models whats a few more bucks. RX crystal swapping is less of a problem. -Original Message- From: Bailey, Donald F [mailto:[EMAIL PROTECTED]] Sent: Friday, January 14, 2000 5:23 PM To: Scale Soaring; 'David Crutchley'
[RCSE] bashin plain bashin you know planes that got hit by the ground
Two stupid substitutes or so I found out later. Finished off my most recent plane in time for F3J, Minot, ME. I had been hard pressed to complete it the night before so figured I could hold the 35" tip sections onto the 52" center section with the carbon joiners and a pass of tape all the way around the wing. I was wrong one of them allowed slight working followed by a dramatic bang as the two tips rotated and ripped off followed at some point by breaking the two bolts on the center section. After making the new fuselage I then put the necessary socket head #4 screws in the wing tips and drilled the pilot holes larger in the center section. It has since gone through much worse and survived. Interesting to be able to break the joiner though and save the wing. On some point in perfecting the fuselage third or fourth version I ran out of masking tape. I usually cover the bottom of the servo with masking tape and make sure it is well bonded. When I put the joint glass in the bottom of the pod I float it with lots of epoxy and jam the servos into it. So since I have no masking tape I reached for the Manco poly tape that I use for wing hinges. I put that on in a very easy fashion since it could be put on with its width in one pass. First landing they popped out because epoxy does not stick to poly. Live and learn. Rick PS I only can afford what I can design and build but I sure look forward to that next NSP catalog.

[RCSE] Bias layup schedule question....
You have to have the answer to another question too. How many layers do I need for handling. Another I have discovered is how much time out of the heat(curing is done at elevated temperature) before I can handle the product. Then you need to consider the bushes and the weeds on the front edge and will the ailerons and flaps be stiff enough. Having mouthed off this far I have discovered that brown Kraft paper 60 pound will work with a spar to quite a high load. But the white paper that weighs almost the same is all fillers and has no strength. I usually pick the front up with two inch wide bias cut boat cloth (6 ounce). In addition the roots will need a band to transfer the load of the joiner. But I am always poking the wing tip into something so I add a small square at the very tip to pick up that area too. This is from the school of hard knocks. But given three layers the tradition has been a full layer to the tip. A second layer to the half and a third layer to the quarter . But since the load rises exponentially at the root we probably should do thirds. With the second layer to one third and the third layer to one sixth.. Then you start saying but this stuff costs so why don't I put it where it does the most good and you start using triangle shapes instead of full covering. Next you beat your head on the wall and say but if I used a spar I could cut down even more. At this point you would be trading your time for the cost Next point of confusion is shall I make the wing two or three piece. Two piece is easier but not as easy to transport. Ever try to get a 3m one piece to the field and back. I was forced to a three piece wing though a truck accident. Newer truck could only be the short one. You can't even put in a one piece 2m. AW!! but the benefits. We discovered at the same time the Conteco guncases at Wal-Mart and now design all planes to fit in these cases. Planes last a lot longer with less hanger rash. But now what shall the lay-up be. Haven't a clue. So I used the typical spar I was using with the pass of heavy cloth at the middle of the mid section to cover the wing hold down dowels and then another Band-Aid at both sides of the two joints. By the way when handling the heavy cloth cut it at forty-five degrees to prevent a raveling mess. Wasteful but much easier. Now isn't this a confused mess of an answer to a simple question!! Rick -- "Date: Tue, 11 Jan 2000 18:44:48 EST From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: Bias layup schedule question Message-ID: [EMAIL PROTECTED] To make sure I am understanding correctly - When laying up glass cloth on a bias (bagged wing) does this mean the cloth orientation is 45 degrees to the span?

[RCSE] 45 degree cut of cloth- strength improvement
If I turn a standard cloth 45 degrees I am supposed to be able to add some to the strength. So using Kevlar or glass in a round boom approximately how much have I changed it by turning and cutting the fabric at 45 degrees. When I broke it because the ground came up and smacked it it was interesting to note that in the straight direction (not 45 degrees) the break was a nice little ring around the whole fuselage boom. So I kept what I had and added more fabric at the points where I had proven it was needed by this stress testing. I think I could either make it much stronger or use a layer or two less if I cut the fabric at 45 degrees. This of course assumes the fabric is the same in both directions. Thankyou.

[RCSE] Dear Winchdoc
I am glad that you are concerned about my health. But actually I am getting along well. You should really be much more concerned about their health than mine. But I am curious about this bit about how hard I am supposed to work. I work just as hard as ever if I am not on one of those dying batteries or one of those diet batteries. Those guys can be pretty pathetic. I have noticed though that some of my friends have a couple of strange quirks. First I would like to point out that most of them are hot under the collar most of the time. I really can't tell maybe they are running a fever. Sometimes they look half drunk the way they walk too; going side to side and up and down. Too bad too cause I know they could do much better if you would only help them too. I noticed you say that they can't work as long but don't be harsh on them they are doing their best. I don't know but it seems to me that every time they work they have to work longer to get the job done. Maybe that is why they get tuckered out sooner. Course if someone had been around watching when I got them real balls you sent me they would have thought something was wrong with me. My! I was feeling my oats!. I used to have a hard time getting up and going. I was so sprightly I hopped right clean loose of my moorings . I used to be so pitiful before that operation that I could be held down with just a small dab of that eye-watering vinegar smelling glue. But when I got that operation I hopped right free of that stuff and graduated to a decent mounting I understand Doc you haven't seen any like me. Course you are probably not old enough. I'm the one with the muscle problem you know I am made up of rectangle muscles and not like my later cousins with round. I was around when Henry was young. I still have one brother here but he is not used much because he hasn't had the operation yet. The younger cousins don't see much use either. Most of them only have two feet and I have four. But we are all old enough to remember working on just hay. Now they give us oats all the time. So you see Doc I am really doing quite well. -- Date: Tue, 14 Dec 1999 08:07:58 -0800 From: Doug Boyd [EMAIL PROTECTED] To: James R MacLean [EMAIL PROTECTED], [EMAIL PROTECTED] Subject: Update on winch curent and BLATENT PLUG Message-ID: AD1DA646FC8BD311A24F009027BBDC3711CD46@NTS-MAIL2 -Original Message- From: James R MacLean [SMTP:[EMAIL PROTECTED]] Sent: Saturday, December 11, 1999 7:13 PM To: [EMAIL PROTECTED] Subject: [RCSE] Update on winch curent SNIP Today I got to test the system with a friend's winch launching high performance 2 meters and my 3 meter Condor. The currents ranged from 220 to 300 amps. This is about 1/2 to 1/3 of the previous measurements. The error source is not known but possibilities are as follows: the previous meter was sitting on the high current wire and magnetic coupling could have played a role. The winch was not the same and there could be something wrong with the other winch. SNIP Could the second winch have been equipped with "Real Balls"? I would really like to see more tests in a before"RB" after"RB" So far we have seen a modest 20% reduced current draw. "Real Balls" ball bearing end plates for the Ford Longshaft starter motor are in stock! (for now, they are going fast.)

[RCSE] happy wives
Maybe he means you should buy your wife a new glider.

Gee Dave, I can barely afford to by my hobby as it is. If spent a bunch money on my wife I'd never be able to buy a new plane.

[RCSE] Winch parachutes
In addition to what Fritz says in the following this is the only kind to have for retrieving through bushes weeks etc when the ground is not perfect. An open chute will open up and catch but these will slide through. I like the ones Mike Lachowski, our faithful moderator sells. He's at [EMAIL PROTECTED] and has a web page at http://www.eclipse.net/~mikel/ They have a net instead of shroud lines that tangle, and last at least 3 to 4 times through the turnaround or retriever wheel before being pulled apart. -Fritz RCSE-List facilities provided by Model Airplane News.

[RCSE] Vacuum switches
Use a foam dense enough to be able to take full vacuum. Using a refrigerator pump turn the pump on and leave it on. If you don't leak gobs of air into it it will run forever that way. If you run a lot of wet air into it it will soon turn the original oil acid and bye-bye windings. Let it run full bore wet air into itself and guaranteed it will be dead in a much shorter time than 48 hours even brand new. You will only leak as much oil out of it in proportion to the size of the leak. No air leak no oil loss. Rick RCSE-List facilities provided by Model Airplane News.
