Re: [RCSE] Finishing a glass wing??
I've seen lots unfinished. Don't think it is a structural issue. I have always sealed the raw edges on my wings mostly for protection from moisture. Flying contests you may get caught in the rain. It would take a little while for the water to get into the foam but I like the extra protection from the elements. Of course coating those raw edges will add some weight. Later... Lee Cox wrote: I would like to hear some of the pros and cons about whether or not the edges of the ailerons / flaps back side of wing should be finished or left as open foam. It seems to me that if edges are sealed with (glass-epoxy or?? )it would structurally be a stronger wing and would help to stop any twist. I see a lot of wings unfinished. HELP!!!

Re: [RCSE] Mantis ballast question
You should make up a few lighter ballast slug of the same weight. Say two 3 oz slugs. When you want more you just add the two lighter ones both front and back. That adds another 6 oz. If you have another set of 6 oz slugs for front and back that add another 6 oz. So you can add 6, 12, or 18 oz. Max you could add and still stay at the same CG would be one 10 oz in the center and two 6 oz front and back. That's 22 oz. HOW MUCH BALLAST DO YOU WANT TO ADD I don't know anybody flying a Mantis that adds that much to get penetration. Don't think that much is needed. But then that is here on the East Coast. Winds usually stay under 20 or so. I think I heard Phil Barnes say he doesn't add more than about 12oz in most condition. Marta Zavala wrote: Have a Mantis ballast question. It was super windy at the Spring Fling in Sacramento this weekend. After about the second round yesterday I was doomed as it got so windy I could not make it out far enough to slope the tree line. I opted not to fly the second day due to lack of penetration. The way the Mantis ballast is set up, three holes, one 10oz slug over cg, one 10oz slug in front of cg and one 6oz slug behind cg, I dont see how one can use more than the one 10oz slug over the cg. Adding the other slugs seems like it would take some major rebalancing before flying. Sure could have used more than the one 10oz slug yesterday, have any of you used the entire balance capability(roughly 24-26 oz??) and if so could you please tell me how it worked out- did you have to rebalance plane- seems to me you would have to add a bunch of weight in tail with fully ballasted plane.

Re: [RCSE] rule clarifications
I think you are confusing two different incidents. One was where the timer had to take over the flight. It was scored a zero. The other was where someone lost sight of the plane. I think they finally did regain sight and continue to fly but a bit disconcerting to hear the timer counting off the seconds.

[RCSE] Mantis - Psy-Antis???
I wouldn't refer to this as a Psy-Antis, as this is Terry's nicer looking molded version of a Mantis fuse with a slip on nose cone. I think of these planes more as a Mantis 'ala Luckenbaugh'. I've seen a couple of guys flying these now, Terry's fuse design with Mantis wings, at the last ESL contest. Terry's fuse design is very nice compared to the bare bones carbon rod and small nose pod. It's got the wing pylon molded right in too, rather than having to assemble the pylon to the carbon rod. There are more of these to come I'm sure, as a number of flyers have gotten Terry's fuse to use with their Mantis wings and tails. [EMAIL PROTECTED] wrote: What am I currently working on?

[RCSE] thermaling hawks
I do not believe that thermaling birds, including the Redtail Hawk has a preference of direction to cicle in a thermal. One reason that I think this is the fact that I have observed what is referred to as 'kettles', large groups of 50 or more hawks in a thermal, usually during the fall migration. If what you say was true, most if not all, these birds would be cicling in the same direction. They do not. Many birds, in the same thermal, will be circling in both directions. I do know an 'expert' birder named Scott Weidensal??(spelling) who has written many books about hawks and migrating birds, and I will definately try to run this past him. Also I will be making a greater effort in the future, when watching vultures and hawks thermal, to pay very close attention to which direction they are thermaling. Daniel Boyer wrote: No, not all birds obey this rule of thumb all the time, but we are trying to look at the big picture, not exception... I am sure the Turkey Vultures have a reason for not always turning left...maybe because their wings allow them to do right turns in a left turning thermal, but most birds will turn counter-clockwise, in the Northern Hemisphere, with the thermal (a quote from a handout that was a page copied from a textbook, which was handed out during one of the lectures that I sat in on this past semester.) I'm not saying I'm an expert (I'm a molecular biologist), just restating what I was told by people that I consider experts...

[RCSE] Rubber Duck Range and range check?
Gordy, Does it matter why Matt had the problem? He apparently had no problem with the stock antenna at his field. When using another type antenna he did have a problem. Weather it was a tuning problem or not his particular setup did not do as well. I used a Smiley Rubber Duck antenna with no problems on a Futaba 8UAF. During some combat a plane hit me and my radio and broke off the adapter so I went back to the stock antenna. The problem I had with the Rubber Duck installed is there was no good way to do a range check. If you removed the antenna at the BNC connector you had almost no range at all. With the 8UAF there is just a short wire that connects the plastic adapter to the regular antenna pickup inside the Tx. My question is this. Is there a way to do a range check with a Rubber Duck antenna setup on the 8UAF or other radios? I liked using it. I had no precieved range problem with the one I had installed on my Tx but I couldn't ever do a range check! Maybe I'm missing something. Anybody tell me how they accomplish a range check with a Rubber Duck antenna setup??

[RCSE] DLG learning curve
Don't know the plane. Couldn't recognize the pilot in a line up. And the tale of the battery and the fuse is just that. The point is that saying a plane broke in use is not good info. If you find out that over time many of a particular design has had structural failures that means something. An isolated event means nothing. Many good planes are going to be broken by bad throwing technique in the coming year. GOOD planes, BAD technique. That's all. Maybe you should ask the 'father of DLG' how many planes he has broken learning to throw discus style. Later... Robert J wrote: Okay I give? Who is the pilot?

Re: [RCSE] Servo damage?
About a year ago I had a problem with some HS-205MG Hitec servos, or so I thought! On landing they would seem to find a new center. I would retrim and center them and the next hard, flap dragging landing would have them out of whack again. I though something was moving/slipping internally in the servos. The problem was actually my fault. I had replaced the stock servo horns with Futaba brand horns, what I though was the same fit to the splines on the output shaft of the Hitec servos. It was in fact just slightly oversized. It held up fine to normal flight loads and seemed fine when putting pressure on them by hand, but on hard landings where I didn't get the flaps up quick enough it would jump a position and end up out of center. After finding the problem I replaced the horns with stock Hitec horns and have had no problems since. Check that the horns are not moving on the spline under extreme shock loads like when dragging the flaps on landing. RB Tom Seitz wrote: After a fairly hard landing, I noticed that both of my flaps remained deflected several degrees when I returned them back to neutral. I seems something internal to the servos has permanently moved the neutral location. The servos seem to work fine, no slop or noise. Should I just subtrim them and not worry, or has some damage been done? The servos are Multiplex mcv2 digitals. Tom Seitz RCSE-List facilities provided by Model Airplane News.

[RCSE] Patton P-51B flys
Thanks to those that posted info on the Patton Aircraft P51B a few weeks ago. I had completed it last evening and took it out in some decent conditions today at Chickies Rock here in Central PA. Nice sunny day, after a storm yesterday and evening that left behind about 5 to 6 inches of snow. West wind about 15 - 20. The P-51B weighed in at 33 oz for a loading of 12oz/sq.ft. I used two HS-85MG servos side by side burried in the fuse using the supplied torque rods instead of mounting them out in the wing panels. Same weight as one std. servo. Used 3/16" thick balsa instead of the coroplast for tails. I have to agree with Steve on the above two items, gives a nice clean look rather than the rods hangin out in the open. One std. servo for the elevator and a Hitec 555 RX with a 4 cell 600AE battery pack. Needed about 1 3/4oz lead in the nose to balance. Cut in a hatch for the Rx to be able to accesss it if I want to change crystals or remove it without butchering the fuse. I set two tubes into the fuse to route the antenna. One down the length of the fuse side and another back up the underside of the fuse to the wing. This allowed the antenna to be fed back to the tail and back up the underside and leave no exposed antenna hanging loose. Test flights were a bit less than anticipated. All in all, it flew well, but the bigger P-51B didn't quite live up to my expectations for speed. I have a Mini P51 by Patton and it flys very fast. Maybe it has spoiled me. Checked the wing to tail and it is very close to zero incidence, maybe just a 1/2 degree positive. I have the CG just a little behind what is called out on the plans. Using the throws recommended by Steve after inquiring where to set them due to no info in the instruct. 3/4" up and down on the ailerons and 1/2" up and down on elevator. I expected more speed out of this plane considering the very thin airfoil and the wing loading. Was I expecting too much? Anyone out there that is flying one of these planes care to comment about it's performance? Any suggestions about wind conditions and ballasting? How much weight for specified wind speed/lift conditions? Any comments on control throws? CG? Thanks for any info, Later, RB RCSE-List facilities provided by Model Airplane News.

Well, it may not be science, but there is some engineering involved! To summarize, the amount of dihedral (or polyhedral) that a rudder and elevator (no ailerons) sailplane has is a major factor in its roll responsiveness and maximum roll rate, and strongly influences spiral stability. More dihedral increases roll responsiveness, roll rate and spiral stability. Airplanes with more dihedral also require larger vertical stabilizers. The exact arrangement of the dihedral, whether it is two-panel dihedral or a six-panel polyhedral for instance, is less important than the effective amount of dihedral that the arrangement provides. The effective dihedral of any arrangement can be estimated and is commonly referred to as "equivalent dihedral angle" (EDA). For what it is worth, I recommend at least 12 degrees of EDA for most rudder and elevator sailplanes. The arrangement of the panels is a compromise between efficiency while thermalling, efficiency in a rolling maneuver, and stall characteristics while thermalling. In short, arrangements that resemble a parabolic dihedral distribution provide a smooth and efficient lift distribution across the span while thermalling, and avoid large variations in lift coefficient across the span in a steady-state roll maneuver. This is good. Arrangements that have at lot of dihedral concentrated in the outer panels will tend to tip stall prematurely while thermalling. Equivalent dihedral angle is explained at: http://www.rc-soar.com/tech/spiral_eda.htm Envision Design sells software called "Plane Geometry" that enables easy experimentation with dihedral arrangements.

What was the application that required reversing the servo rotation? does it have something to do with the mentioned 'Escape'. This is the 6 servo wing?

Re: [RCSE] Contests and LSF Levels (2nd try)
This statement was made by Tom Broeski and it was made as a SARCASTIC remark and he of course did not mean it. It was a remark made to try to make his point about having more than two classes (sport and expert) in the ESL contests. He is for more levels so he made the comment about why the need for 5 levels in LSF. Why don't we just have level V of LSF? [EMAIL PROTECTED] wrote: At the beginning of this thread someone wrote: Why does the LSF not just have the level V. It is such a waste to promote the sport at those lower levels. I am sure there would still be several members and couple of level V's anyway. Who needs the level ones, two's and threes. I'd like to address that. The early levels of the LSF program are pretty easy for an experienced pilot but they do require participation. This is a place where the experienced pilot can get together with less experienced flyers and together work on the lower levels. I was still pretty new to rc and soaring when I started LSF and the lower levels generated enthusiasm for the sport and helped me to become a better flyer. The most active period my club ever had was when a group of about ten of us were all working on LSF. After a few years I made Level IV and began working on Level V. The first entry on my Level V voucher was dated 1977, the last, 1997. During the next "few" years I worked on Level V tasks. I considered them all "doable" except the contest requirements. For twenty years I flew in as few as 10 and as many as 20 contests a year. In almost all of those contests I competed against 2 or 3 Level V's, and a bunch of people who could/should have been Level V's. I had nearly given up hope of ever making it. A little determination, slightly above average flying skills, help from other LSFers and some good luck got me that last win. I was a little luckier than some of my other friends who, because of their age and participation levels, probably will neven make Level V but they are proud of their Level IV's and the parts of V that they have done. Other friends are close and still trying--and might yet make it. None of these people would like to see the rules change. Huzzah to them!

[RCSE] Wanted- Competition flyers
Dennis Phelan wrote: Dudes, Are there really only 50 competitive fliers in the ESL? Does the website only list the top 50 fliers, top 17 sportsmen and top 33 experts? If there are, I[not being an ESL member] would ask why someone would need more classes? = Dennis Phelan I think this is the point. There are about 45 to 50 core ESL flyers that compete on a regular basis. There are others that compete, but are not members of the ESL, and are not listed on the ESL site. If you don't pay dues for the year then even if you compete in a ESL contest you are not listed in the year end standings. You can still take home a plaque at a contest, just not get in on the year end trophies. Year end standings are made up of your six best scores for the year. Scores are calculated as a percent of the winners score for that contest. There are not enough flyers to support many classes. In order to add more classes you need to get more competitive flyers into the league. There have been discussions on how to accomplish this. I know there are many sailplane flyers out there that enjoy flying but don't compete. Many may not feel they are good enough or don't feel confident enough to go out and compete. Some don't fly TD stuff. Some just don't want to spend the time and money it takes to travel to contests and compete. Any good ideas from other clubs/leagues on how to attract more flyers into competition? How do you get the guys out that love to fly but have not been bitten by the 'competition bug'.

Re: [RCSE] servo calculator
Possibly the calculator is haveing a problem with the extreme deflections of the flap function,(90 degrees). I also think that you are using some unresonable numbers as far as speed. 75mph is not an unresonable number as far as speed of some planes, but I know when I pull flaps on my TD ship I am not normally going anywhere near 75mph. I do sometimes dive down from altitude but do not come screaming in and drop the flaps at that speed. If I have time and have planned things right I may pull on flaps first and spiral down slowly. In this case the flaps come in with very little speed and then pull out and off the flaps. Also when making the landing approach it is not at the extreme speeds you are referring to. I am using Hitec HS-225MG servos, one on each flap and as you have said they are up to the task for a 65 - 70 oz. Unlimited plane. Try inputting some smaller value for speed and see where the torque values come in about 45 oz. RB Bill Johns wrote: Greetings! One of the really neat things about the Multiplex web page is the calculator that will help predict the right sized calculator for an application. check out: http://www.multiplexrc.com/calcservo.htm OK, given that it is an approximation at best, I still get some really strange numbers. I'm probably using it wrong. Given your basic 125" sailplane. weighs say 70 oz, flaps are 2x25 inches, they deflect 90 degrees, the wing has a 10" chord and the plane is moving at say 75 mph. Yes, this is fast, but not unreasonable for a dive. For me the servo calculator gives a required servo of 112 in oz. This is a huge servo. Most of us would find a Hitec 225 MG with 55 in oz adequate. On the other hand, given an aileron on the same plane, again say 2"x25" that moves only 30 degrees then the required servo must carry only 37 in oz and an HS 85 at 42 in oz.is more than adequate. Am I doing this right? Whenever I try to come up with a value for flaps, it always seems about twice as high as folks use successfully. What am I missing?

Re: [RCSE] servo calculator
Just did some quick calculations on the servo calc program and if you drop the speed value down to 50 - 55 mph you will come in around the 55oz torque value of the HS-225's. I still feel this is too high a speed to be pulling full flaps for normal TD flying. RB Bill Johns wrote: Greetings!

Re: [RCSE] Low-end computer radio
High end computer radios MAY be more than the new guy needs but if you buy 2 or more lower priced ones you'll have the same money into your epuipment. I went thru the multiple radios thing. Keeping them all charged and maintained. Hauling many Tx's along to the field, ect. Finally got a Futaba 8U a few years back(no I don't want to argue which radio is the best) and now I fly all my planes on that one radio. Slope, HL and TD. In my mind one radio is the way to go.

Re: [RCSE] Antenna/servo flutter
Is it possible that the reason the servos are no longer jittering is due to the difference in the pattern of the signal being sent out of these two different antenna types. I'm not the expert on this subject but the way it was explained to me is that the regular collasping antenna generates a cone shaped pattern while the rubber duck style antenna generates its strongest signal directly in line with, generally out the end of the antenna. So, while holding the plane in hand at the winch or high start the cone shaped signal would possibly affect the servos while the rubber duck antenna would not. Not that this means one is generating a stronger or weaker signal overall. The rubberduck antenna may be better for those of us that have that habit of facing our planes while we fly. This gets the antenna pointing mostly at the plane. The very spot that a regular antenna is suppose to generate its weakeest signal. At the moment I use a regular style antenna andhave experienced no problems with it. Anybody have any range problems with either style antenna? Anybody that really knows about this stuff have an opinion I would like to hear from you. Thanks, RB Art Mcnamee wrote: Hi Bill, I assume the Power Duck is a short rubber ducky type of antenna. If so, the servo flutter is probably loss of signal strength and torroid beads would have stopped the fluttering without loss of signal strength.The signal strength won't cause much of a problem as the receivers we get today are pretty good but out on the fringe area the signal strength could make a difference. I no longer have a Spectrum Analyzer to measure the signal strength but I'll bet $10.00 to $1.00 there is a difference and the full size antenna is the winner. Thermals, Art Bill Rose Haymaker wrote: I would like to thank those who suggested Smiley Antenna for replacing the original telescoping antenna with a R/C Power Duck.

Re: [RCSE] Using a tow plane to launch sailplanes
When towing a glider the pilot of the glider MUST NOT rise off the ground too quickly. The glider must follow the tow planes flight path. The limited towing I have seen was done at a brisk pace in some wind, maybe why the steep climb, and mostly straight out. Rising very quickly. I don't think this is the required flight path though. Just maybe the safest way with the conditions that day. [EMAIL PROTECTED] wrote: Hi all, The other day a friend of mine asked me to tow up his sailplane with my IMAC plane and I agreed. The results were interesting but not what we had intended. Both planes survived in tact but the glider never got more than 20 feet in the air before the two planes separated. The IMAC plane hadn't left the runway yet. So the question I have for this list is how do people tow sailplanes up to altitude? Does the tow plane accelerate fast or slowly, etc. I'm looking for a prescribed procedure on how to safely do this. Thanks, John RCSE-List facilities provided by Model Airplane News.

[RCSE] Mine isn't better than Yours
All, I have been following the posts about servos and Rx. I just had to throw in my two cents. I have invested a good bit of money in radios, planes and servos over the years. I don't fly the latest molded plane or have the most expensive servos or even have the latest design Rx. I have a foam, fiberglass and carbon fiber plane (getting to be in the minority - many molded), a Futaba FM radio and Rx and some of those cheap Hitec servos. I probably still have about $1000 just to get one plane in the air. This gets a bit less expensive for multiple planes due to the same radio for all the others. My point is I feel I have put enough money into the hobby to be competitive. Over the weekend, flying an ESL contest in Lancaster PA, I beat many good flyers with better equipment. I placed 8th in Expert class(my first year in Expert - they kicked me out of Sportflyer class last year)both Saturday and Sunday against good flyers, Gordy (he graced us with his presence) being one of them with his molded plane and high priced servos. I blew a 4th place finish on Saturday with a short flight in the 8th and final round. I think we all know it's how well you can fly what you have and not if you have the latest most expensive 'stuff'. Having a molded plane and the top of the line, most expensive equipment WOULD NOT have gotten me in the top five on either day, only better flying. Mine isn't better than yours, but one of these days I may just slip in there for a win Fly what you got and have fun doing it. Later, RB RCSE-List facilities provided by Model Airplane News.
