[RC-Monster Mike]

With the 52t spur, it will accept 15-24t mod.8 pinions(small pinion limited by the motor diamater rather than the mount itself). With a 36mm diameter motor, it will accept 12t - 24t mod .8 pinions. The motor can be installed/removed and/or adjusted with a single screw that is easily accessible. Pinions can also be swapped without the need to remove anything aside from the pinion itself(like all our mounts).
