RE: Biplane aileron setup
You will find that out in the trim flights, no one can say how a plane is going to act. Each planes set up is a bit different from plane to plane. I also use an old JR match box for some set ups. You can adjust the servos through it. I also don't ever use extensions, I solder in any wire I require for added length. I have had and seen too many extensions get sluggish with corrosion unless they are pulled and cleaned once in a while. If you do use extensions then pay the extra money and buy the gold plated ones.
