yours is the worst case senario and likely has the full three channel dihedral. Sit the wing assembly on a table with one panel flat on the table and measure how high the other wingtip comes above the table near the tip. The stock dihedral the wingtip will be around six inchs above the table and that is far to much when ailerons are used. reducing this to around three inchs then the ailerons will work nicelyl

Yes the aileron conversion can and will be a failure unless dihedral is reduced when you find the controll response is far slower than that avalible when using just rudder!

The typical fix in this situation is a last minute resort to modern electronics and mix in around 25 to 30% rudder to aileron. Thats not simplifing anything and you are far better off if you want airerons to do it right or not do it at all and fly your airplane in its already simple setup as a three conctrol. I have flown many three control Kadets and the common attitudes that you cannot do aerobatics is BS and most fly wonderfully.
