I have a Airfield 800mm Corsair warbird. I know it is not the best quality plane but here is my question. When I go to take off she lifts up about 2 feet then makes a hard left back to the earth. What I have noticed is the tip of the right wing is 3/8 of an inch higher than the left. Being that it is foam can that be adjusted? I am using a spectrum DX6i with a Orange receiver that has flight stabilizer. Any advise will be helpful.
