@matas17 Yes, I just meant for ideas. This is something I have myself looked into, and a piece of advice would be to look at LMG gearboxes. It is going to be difficult for your motor to be in the standard place for v2 and v3 engines since your pistol grip will be forward of where your engine will be, and a LMG gearbox doesnt have the motor in the grip.
@SeniorSpaz87 are they reliable gearboxesm since i never worked on one. And the only reason i was thinking of V2/V3 because i would try and find a way to get mosfet installed.
