[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] Importance of foam core cutting sequence (long)
This translates into wider kerf at the "slow" end. With that said, I'm not real sure but that "gravity-powered" cutters have the same problem. They do have the same problem. It is especially well illustrated when cutting wings for a delta in which the root may be twice the tip chord or more. Doesn't matter what's doing the driving. In this extreme taper situation, it is obvious that most of the pull work is being done at the root templates, where the wire is doing maximum speed within the system. At the tip, the pull cord is still doing its job, but it barely has to work against any resistance, because the wire has such a long time to eat foam that there is virtually no resistance. In fact strange waviness in the foam at the tip can always be expected to some extent because the hot wire spends so much more time in so much less foam that the surface is affected by the constant radiant heat. Its all kind of fascinating once you get to thinking about it. Lift, Scobie in Seattle RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] Re: Alternative Servos
If everyone looked in their "old servos" box and listed what they have, it might make the point. I looked and have 80's 81's, locked up 255's, Dads, several different CS servos, an assortment of Airtronics servos (4 141's that won't center right, some 151's I just put new gears in and they are fine now, a couple 131's and some standard servos) and two Volz wing max (broken shafts) and I had some Critter Bit servos until Karlton said to send them to him. I have sent several Hitec servos in and they were replaced at no charge. Now... the last two years (and with some major crashes included) I have not had to replace one MPX servo. I used to go through 141's like crazy. I have Micro 3 BB's and FL's and they just keep on ticking. In the long run I could have been using the best mc/V2 servos and actually saved money.

I agree with your choices - with 1 possible exception. I used the HS85's in the ailerons of a Sapphire wing, and on a really hot zoom they would give up. The ailerons would flutter and I'd have to swap out a gear set. No huge deal, I learned to slow down a little. It should be noted that the ailerons on a Sapphire are huge, long, and a little "springy" - factors that can all add to the problem. What kind of plane are you putting these in? happy trails - Rob I ordered HS225BB's for aileron, elevator and rudder. HS225MG for flaps. Could save a bit of weight with HS85's for ailerons.

Re: [RCSE] Electrical Connectors for Wings
Hi, I use connectors from Digikey. These 4 pin connectors similar to the Deans but much longer. They are made by Waldom/Molex, are gold plated and .450" long on the male end. The other end is .172" for soldering. The receptacle is also gold plated. These connectors are very nice. See Digikey at: www.digikey.com A HREF="http://www.digikey.com/DigiHome.html"Digi-Key Corporation /AThe part numbers are WM5004-ND for the male connector and WM2102-ND for the female receptacle. You can also see a good picture of the connectors at the Waldom/Molex site see: A HREF="http://www.molex.com/scripts/productsearch.cgi?RT=BROWSEFAM=wbUS=IDL= 2803SEQ=1PRODUCT=2478,08xx01xx%3B+2139,09507xx1,+09503xx1+-+41661,+2648xxx1, +2651"Wire-to-Board Application/A http://www.molex.com/scripts/productsearch.cgi?RT=BROWSEFAM=wbUS=IDL=2803S EQ=1PRODUCT=2478,08xx01xx%3B+2139,09507xx1,+09503xx1+-+41661,+2648xxx1,+2651x xxx Hope this helps, Tom RCSE-List facilities provided by Model Airplane News.

[RCSE] servo lead question
I have a used CR Climax that I purchased from someone through the internet. It came with two Cirrus CS-20 BB sub-micro servos with Airtonics connectors. I would like to clip the Airtronics connector and splice on a Hitech connector. The servo leads have one red wire (an end wire) and two black wires (the center wire and the other end wire) The wire color chart on the back of the package of one of my servo extension wires indicates that the for Airtronics connectors, the red wire is the positive lead, the center wire is the negative lead and the other end wire is the signal lead. The same chart indicates that for Hitech connectors, red is positive, black is negative, and yellow is the signal. Is it safe to clip the leads and splice on my Hitech extension using the wire color chart as a guide? Thanks for any advice anyone might have regarding this matter. Cliff (I have really high expectations regarding the anticipated performance of my CR Climax. It has a small sticker on the wing indicating that it was flown in the 1999 IHLGF! To me, thats like buying a used car and then finding out that it was raced in the Daytona 500!) RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] servo lead question
Hi Cliff, your servos should work fine if you change plugs. The only thing is make sure you get the red (B+) in the center of the plug and the middle black wire (B-) to the edge of the plug. the other black wire is as you said, the signal or information lead and goes to the other edge of the new plug.
