Hello Everyone, I am new to the modern RC world and purchased my son the Torment 4x4 last year for his birthday. The motor burnt out and I bought a replacement, the new one is 12t vs 15t which was in there. The salesman said it did not make a difference, this one would be a little faster. This is the ARRMA 550 12T brushed motor. Anyway, I was looking online for videos to make sure I didn't miss anything swapping them out but it appears mine is different than most as all the videos show the wheels had to be taken off and the motor was held in a housing, this is not the case on mine. I assume this is a cheaper or diff model (4x4 vs not maybe?). Anyway I pulled the old motor trying my best to note placement, etc. Now when we run the vehicle after a short while the motor will just spin. I assumed the pinion gear backed off the drive gear(?) not sure of terminology, so I matched them up and it ran again but every time it starts doing it again. Am I missing something? I am not sure what I am doing wrong here. Any advice would be appreciated!
