ISSUE
Can probably add that the main gear and shaft are a press fit and the gear will shift until there is about 1/16-inch gap between top of gear and the frame.

SYMPTOMS
Heli won't lift and vibration occurs at high RPM (blades appear out of track).

FIX

Remove landing skids and hold opposite end of main shaft while pressing the main gear until there is approximately 1/16" of the main shaft end protruding out of the main gear.
