Gemfan Ally Backplate Nylon Spinner 63mm White
These plastic spinners feature a molded plastic spinner cone with a machined aluminum backplate.
The Spinner cones are attached to the backplates with a pair of M3 x 6mm hex socket head screws. The aluminum backplates have lightening holes to decrease weight and rotational mass, and have a raised knurled area on both sides, around the center hole, to provide a firm grip on both the back side of the propeller and on face of the motor’s prop adapter.
The spinner backplate has an 8mm hole in the middle and comes with a set of plastic reducing adapters so they can fit onto 6mm, 5mm, 4mm or 3mm motor shafts.
