Minnflyer - Bending the torque rods... that is something that I have always been very hesitant to do because I am afraid that the hole in the aileron (or elevator or whatever) is just getting bigger and that the rod itself isn't really twisting. So at the end, you have a loose connection to the rudder (ie. there is some play in there). Is it smart to bend torque rods while installed? Won't the soft balsa aileron around the torque rod just compress?
That's what happened the first time. But I immediatly stopped bending and just took the aileron of again and then used a wrench to hold back the torque rods. But the weird thing is, I got them even once, but now it seems like the torque rods, in time, automatically bend back to their original size.

The reason MinnFlyer had you connecting to the 6 arm servo that way is to give you "differential ailerons". The purpose is to give more "up" travel than "down" travel. This reduces the drag induced by the lowered aileron compared to the raised aileron. In turn, this reduces a condition known as "adverse yaw" which is why you need to add rudder to make a coordinated (smooth) turn. This condition is especially relevant in full scale a/c where they even design the aileron itself to assist in the differential.

LoL, a guy from my hobby club came to have a look at my plane when I finished it and I showed him the aileron problem. He said that ailerons should move down more then up. Guess he was wrong !!!

It seems to me, you may have the same problem I had. The cut-out slot in the wings (which the ailerons rods travel back and forth in) are improperly cut. On my alpha, I had to use the dremel tool and complete the slots in both directions on both wings. Be careful, not to take out to much, or go through the wing.
But, smaller amounts of movement is better when learning to fly, makes the planes controls softer. Not so radical.

I already dremeled out a bit. Caus I to had that problem. One of the ailerons couldn't move as freely as the other one.
One last question: Do you need much throw on the ailerons on a trainer ?
thx for all the replies,
