Ok here is the deal. I have a GP PT-40 that I built from a kit and the wing is a scratch built from the plans. Everytime I try to take off the plane pulls right when the wheels start to come off the ground. It usually ends with the plane nose over in the dirt on its back. When I do get it off the ground, it SEEMS to fly ok. I don't feel that I am adjusting to keep it going in line. I have checked the control surfaces and they seem to be OK. I buddy of mine said that there may be too much right thrust causing it to pull over when it leaves the ground. I am using a OS .46fx with a APC 10 X 6. I put a .40 on the plane last night thinking that I would see if a smaller engine will create the same result.

Any thoughts? I have looked at the wing and to my untrained eye, it looks to be pretty strieght.

Thanks!
