This thread has me torn in two directions:
Agreeing that ailerons are a good thing as learning to fly without them would be problematic at best
Agreeing that ailerons are not needed after building a Sig Kadet Jr that was designed with significant amounts of dihedral and no ailerons. The directions even say to connect the rudder to the right stick to learn how to use ailerons but not how to use a rudder.
Since my first Kadet was destroyed in a move before it was ever flown, I'm building another one from plans with all the diredral removed and barn door ailerons three bays wide added to an extended wing. It won't be an aerobatic plane by any means but it will be one that flys
