I'm a pro at fixing them by now
Shouldnt take me more than 5 min or so to fix the wiring issues and less than another 5 to install your gearboxes while I'm at it! I'll get it fixed so fast you wont know it was gone hehe. Oh and I REALLY enjoy fixing stuff. I think I spend more time fixing and building than operating on purpose! Tinkering is just too much fun.
