I've heard that quite a bit, that planes have to be setup for either pattern or 3D. Maybee you can use D/R for both types of flying?

Anyways, as soon as I can get about 200 bucks, then I'll put in an e-power system in the Extra. The one I've chosen should perform great, and do some 3D stuff. The only concern I have is that the ailerons are only about 1" long, and stretch the wingspan. Elevator and Rudder appear to be able to give off sufficient controll.
