I thought that the motor was supposed to be RTFfrom the factory, other than the break in period. I could almost lift the head from the motor they were so loosely installed. It took several turns of the good ole allen wrench to get them tightned properly. That
should have been done from the factory! Lesson learned.

I've never not gone over a motor for loose bolts before installing it in a helicopter or aircraft.
