SII-2205 Shaft Kit
The Scorpion SII-22 series of motors are built with 3mm hardened steel shafts that will last through countless hours of flying fun, but occasionally, on a "Less than Perfect" landing, you may bend or break one. For these occasions, we offer factory replacement shafts for all SII-22 Scorpion Motors. Our Motor Shaft Kits include an original equipment factory shaft with the setscrew keyways already cut, a new shaft retaining collar, and a replacement setscrew for the retaining collar.
The shaft for the SII-2205 motors measures 3mm in diameter, and is 42.0mm in length. The shaft kit will also fit other brushless motors that require a 3mm shaft of this length. The shafts can be cut shorter with a Dremel tool and a cut-off wheel if necessary to fit other motors.
Note: The shafts in the Scorpion motors are a slight press fit into the aluminum front housing. The shafts will not just slide out when the setscrews are removed. They need to be pressed out in a bearing press, or in a drill press, with the front housing of the motor supported in a block of wood to prevent warping the front housing.
