this is the best gearbox set up video i've seen. the other ones are just crappy pictures with text instructions and crappy music. this dude actually talks and the pictures clear. 5 stars

Is this gearbox good to a weaker M120 spring?

[ElectroPulse93]

lol... the trigger always causes MUCH more trouble than the anti-reversal latch, for me at least :)
