I am looking to get a 50cc gas 3D plane and would like some advice on what would be a good one to start with. The question that i have is what planes are the best for not needing coupling and mixs added in. I say this because i am loving the look of the Great Planes Patty wagstaff and a friend at the field is going with the Great Planes Sukhoi 31 because he says that it does not require coupling like the extras and edges. I would like that but do not like the look of the round body airplanes. Can anybody tell me is there really a differance in the yaks, extra's, and edges that are out there???
