Hello Rc enthusiasts! Im new to the rc game and need some help. I purchased an arrma 4x4 mega. Within the first ten runs my motor went out, no big deal got a replacement but now i have a problem, I didnt pay too much attention when i took the gearbox apart (i needed to change my pinion gear) now i cant put it back together if someone could please link me to a video or contact me and walk me through the process i would appreciate that very much. The exploded view isnt doing me any favors.
