im building my second plane, my first low wing, and have a question about mounting the servos. ive read many times the benefits of having the aileron servos mounted in the wing, which i can fully understand. im building the super sportster 60, powered by a .61 os and the wing is plenty fat enough to make it happen. as you all may know, this kit has a single aileron servo which controls both ailerons. i have a nice pcm radio, and even though im presently unable to take advantage of the cool mixing features, i would still like to set up the plane for when i can. i dont know why, but i just feel that its a tighter, more responsive, and in my novice opinion, easier to install and maintain.
has anyone modified a kit and did something like this? is this plane worth doing it to? should the aileron be shortened any amount of length?
thanks for your time and interest.

Although I haven't had a Super Sportster 60 I have extensive R/C experience. The extra servo will give a better aileron response, although since it's your second plane I assume that your flying skills may still be toward the learning curve. In this case, the response speed may not be essential for you. Response speed comes into play when you want to whip the plane around for advanced aerobatics. I would not recommend this for learning on your first low wing. As far as shortening the ailerons, I would build the Sportster according to the instructions. Hope this helps. Good luck and happy flying!

I built the SS 60 last winter and did exactly what you want to do. I would not modify the ailerons size at all, but it is easy to install dual aileron servo's in the wing.

There are several methods for mounting the ailerons out in each wing panel. The method I used on my SS was to just build a couple mounting rails out in each wing panel just behind the main spar. Then mounted the servo so just the servo horn will extend beyond the depth of the ribs. When covering, you just cover around the servo arm. This is a simple and effective method. BTW - I used a couple of small balsa pieces around the servo to serve as something for the covering to stick to.

I modified my Venture 60 the way you want to (two wing servos). Check out www.btemodels.com I think the mods for the Venture are published there and would work for your Sportster.

I'm not sure you'll actually need or use the dual aileron ervos in the Sportster. (It fly's very well with a single servo and slows enough on landing so flaperons aren't needed.)

But I'd say do it, just for the experience. Then you CAN program in flaperons once you get use to the planes characteristics. It'll get you acquainted with using flaps on landings, even if they're not needed.

Not only will the experience in building be worth it, it will also get rid of that dreaded torque rod set up. (in my case it has nothing to do with the quicker response time, etc.) I just don't care to mess with them. If you need to do a repair in that area.... the repair job will also go easier without a torque rod. I damaged a wing once, and repairing the aileron and torque rod area was difficult. ..... lownslo....

Having individual servos for each aileron also makes it easier to set up your throws and centering of the servos. You can perfectly center each aileron independently and get less aileron differential.

Harry Higley offers an instruction book entitled, BIPES. It is a great book for the BIPE builder and well worth the coin. Anyway One of the tricks and tips offered as a how to was dual aileron servos (Y Connect). Higley described (with pics) several neat install methods - very neat. Radio Control Modeler magzine offers an on-line, (book) retail @:
