I think someone with 3yrs. experiance can easily handle an aileron plane with a flat wing.
Combat is just a different experience than flying when your the only plane in the sky. In combat you have to learn to take your eyes off your plane to search for targets, be able to reaquire your plane and go get the streamer. Starting out, the FNS was the best combat trainer because if you lost it, got disoriented, whatever, you take you hands off the sticks, and the FNS would just fly out straight and level and give yourself a chance to regroup and get back in the action.
It is just as easy to build and alot more responsive.
You've never chased a rudder plane in combat have you? Rudder planes fly different that aileron planes, so they can be very hard to catch with an aileron plane!
