If you have an opportunity, take a couple of pictures of a Kadet Senior ARF's aileron setup. I would draw up some basic aileron plans and tape them over your original plans. It will take a little time to make the mods, but this plane flies great with ailerons (and differential throw). I have several planes ranging from 1oz electrics to a 80" twin, but none of them are more fun to fly than my Kadet Seniorita! Note, I have flown a couple of Seniors as well and they are just as much fun as my Seniorita! Good Luck!
