RCG Racing Wind Speed/ Storm Rider bezkartáčový motor pastorek a stavěcí šroub pro bezkartáčový motor

The pinion gear teeth mesh perfectly with my brushless motor, and the ser screw held tight through a full pack without loosening up. Exactly what I needed to get the Storm Rider running smooth again.

I swapped the stock pinion on my Storm Rider and these fit perfectly, the set screw held tight after a few runs. Saved me from buying a whole new motor just for the gear.

The little ser screws are machined clean, no stripped heads out of the bag, which is rare with these tiny parts. Fit my Storm Rider's motor shaft perfectly and the pinion locked down solid with zero wobble after a few runs.
