Pinion Nylon 6.5mm diameter 11 Tooth 2mm shaft (10 pack)

1.95mm aperture.
Fits the 2mm shafts on FC-130, Flat-6 and boxer motors. Tight press fit onto smooth shafts, or fits nicely on the splined shafts for sidewinder and angle-winder use - May need loctite to prevent slippage when used with more powerful motors.

6.5mm diameter, 0.5 modulus

- This is equivalent to 50.6 diametrical pitch - in plain talk, almost identical to the stock pinions on Scalextric, Scaleauto, Fly, Slot.it, NSR, Slotting Plus and other cars.
