Had my plane for almost two years. 46 TT has been plenty of power for anything that the plane will do. You will love the way the plane handles wind.. When it's to windy for every one else, you will still be flying, and they will be looking in envy. Go with a APC 12.25x3.75 .. I thought my was a little fragile on the landing gear-- moved CG back And the lady lands like its on rails. Have had tank problems, keep a eye on it. standard servos a must. This is a very under rated plane.
