My friend built a Tiger 2. I have never had a problem with any Tiger 2's or Sky Tiger from Goldberg. This plane fly's awful. Its a 40 size plane with a TT 46 and on take off it wants to turn hard left. It is barley flyable. I've had to land this plane with all the right aileron and some right rudder. THe plane is built straight and true.
He's gone over the plans and rechecked the CG, lateral balance and engine thrust. My question is, What is causing this? I've had an expert pilot look at it and fly it. He had the same problem. He thought it was worse when you applied up elevator. Does anyone have a thought on this? Thanks for your time.
