i use to fly a super sportster with the .46fx. if you want a hot plane, get a tuned pipe on it like i had. i swear it did 90 MPH flat out WOT and exceeded over 110 in a dive! I am suprised with all the full throttle terminal velocity power dives i did it never fluttered. It was my 2nd plane and also a very awsome one. i dont know why the guys above said it was a 3/4, because its not. it lands a little hot, but not too bad. good luck! BTW: senza destroyed the extra last week. i think he failed to mention that. without an engine it turns into a lead sled!
see me and my planes and also senza and his planes at www.scoob-e.com
