Default RE: Bipe aileron setup?!


ORIGINAL: insalacosm

Great thread, but I have a question: If the ailerons are connected at the trailing edge (or just aft), will the throw be the same for the upper and lower? I'm thinking that what matters is that each aileron is connected at the same location relative to each aileron, so whether it is above, below, or in the middle (at the TE), it should work fine as long as both ailerons are done the same way.
thanks
Steve
Hi Steve,

Yes it really does matter if you want the best performance from your plane. I built a 1/4 scale Waco YMF-5 and originally rigged the ailerons as shown in the first photo. The top aileron moved a greater distance than the bottom aileron. When the top aileron came down it was hitting the wing before the bottom aileron came close to hitting therefore the rolls were very slow because I didn't have enough total aileron travel.

To correct this I made a tab that attached to the bottom wing to cause the two ailerons to move the same amount. See second photo. The plane roll rate was much better after this.
