OG Traxxas Rustler, replaced motor with a Traxxas 550 but the shaft is too long?
I had a reedy Radon 12t that I thought burned out, so I bought Traxxas 550 motor but the shaft is too long and the pinion gear doesn't slide down more. What am I doing wrong? I also figured it in the brushes on the reedy wore down but that's a different issue now.
