I just got my high speed modular gearset today, put it into my G&P mechbox, put in a modify tappet plate, and closed the mechbox, then the motor wouldn't turn it. After poking around a bit, I realized it was the tappet plate that was jammed against the gear or something else that wouldn't make it turn. The same tappet plate moved fine with XYT gears. I then swapped in a G&P tappet, and the same problem occured, although the tappet could move back and forth very slowly this time, the gears still wouldn't turn. Finally, I put in a DBoys tappet, and after shooting off a few rounds, it now works fine. However it still sounds worse than my shimming on the XYT gears, although that's probably because my shimming set the gears too far apart.
