My current project, a Boeing 737-800 takes off and flies, but when it gets some speed up it lists to the right. On the ground, it turns to the right a bit, and in the air it rolls to the right. I have checked everything I possibly could. I checked for duplicate parts, made sure the airfoils are how they should be and made sure the engine power was the same for both engines. Any help is appreciated.
