I pulled my motor and pinion to install a Hobbywing heatsink and fan. I must not have tightened down my set screw for my pinion gear tight enough, and it came loose and shredded. Is anyone running the extra pinion that Arrma warns against using, except for speed runs? I mainly bash and am running the backflip tires.
