What are you all doing now with the High Torque servos on 40% aerobatic airplanes

You can get ailerons as stiff as you want by using cf veil and cf strips running down the ailerons. Use a 0.5 x 10mm cf strip. Use one on top of wing and one at bottom. I just got done doing this veil/strip combo and it’s as stiff as a 2x4. I showed this technique in one of my tip discussions in our newsletters.

A single HP A700 would be fine on ruder IF you can afford to lose the weight of a servo in the tail, which will be tough to do with a 200 on the front. If you need to tail weight you might as well make it functional. I would not go with a single on the ail though. It's not an issue of moving force but that a foam ail with that much surface area just does not have the torsional rigidity to handle being articulated from a single point.

Cam....although only a 35% Extra I'm using 3 of the Futaba A700 servos on my Krill. One each on the ailerons and rudder (pull/pull). These composite ailerons are pretty stiff plus I've added a center span CF rib. Haven't maidened it yet....although tomorrow (May 5th) is looking good here. This much servo power is overkill on a 35%, but WTH...🤣

I will say this....keep your fingers out of any pinch-point areas when you fiddling with these.....or you may be fiddling with one less digit!!!

I have not used them. But I would use them on my rudder, not much different than ganging servos. I would be leery of the ailerons because you lose that second point of contact (unless you have that tube setup like the Comp Arf)

Question for you all?


What are you all doing now, on your 40% aircraft

if you have stepped up and using the newer very high torque servos

each servo that has over 800 or 1000 ou/in of torque

DO you still use two of those on the rudder?

DO you still use two on the ailerons?

Just think using one less set up on an 40% airplane cuts down the price of the servos by over 200 dollars.

But that is just as an aside.
