I flew her for few mins and everything was working OK, until came down from hovering 3 feet above ground. Back to the bench and I found out motor B was moved and the pinion was not engaging with the gear
I guess I have to find longer screws and use the washers and until then no more flying. What
Extreme flyers are using the same screws with not only the washers but along the heat insulation plate under motor B. Daaahh Any clue where can I find longer motor mount screws?
