This was my first plane and I still have it......I even still fly it.

Even as my first plane, I built it with LESS dihedral than what the sport wing calls for. It has been an EXCELLENT plane to both learn on and continue to fly. I have the OS 65LA on it and it has ran flawlessly from day one. I have lost track, but there has got to be 5 to 600 flights on it by now.

Hindsite has shown me that it could have been built lighter, but it really isn't neccessary. With any 60 size 2 stroke, it has more than enough power. Your 80 4 stroke should be a good choice
