The most common problems with your AEG, and how to fix them.

My gun is making a whirling noise but not shooting.
I can feel the motor running but the gun just doesn't fire. What now?

This is a common problem caused by the natural vibrations from the motor of your AEG. Through use, the height of the motor shifts out of its optimal height and may lose contact with the gears. The whirling sound you hear is the Pinion gear of the motor spinning without making contact with the Bevel gear, or first gear in the series of your GB. Consequently, the height of the motor needs to be adjusted periodocally for the motor and gear to maintain contact. Watch this video to see how eays it is to tune yourself.
