Ever since I received my AC it has seemed to drift slightly left when going forward. I don't notice it when the aircraft has any altitude only when it is near the ground 5-6 feet off the ground. It may very well happen in the air but it is much more difficult to tell. I am also not sure if it is really drifting or if it is optical illusions. Just curious if anyone else has it or if I am just being nitpicky.
