REVED M1-644 MC-1 Spur Gear Holder Set

Aluminum spur gear holder set for [MC-1].
A center lock method is used in which the spur gear is sandwiched between lightweight aluminum holders and fixed with a single nylon nut.
Spur gear replacement is faster  than the conventional 4-point screw fixing method.
There is no need to worry about centering the spur gear because it is positioned by the four pins equipped on the spur gear holder.
