Everything checks out OK. I do see a wobble in the main gear as if the center hole is off center. I see all these videos that show trimmed so well that lift off and hovering is almost perfect. This bird I have is all over the place. I want this bird to lift off and hover hands free except for the throttle. Maybe I am asking to much? Or maybe I am asking to much from me. I can control it on the floor in the one foot square except the forward thing. I can get it to stop the backwards drift. Oh well. Maybe I don't have it trimmed correctly. I wished the guys that have theirs trimmed out so well made a video on how they did it.
