FEATURES
The Scorpion 30mm series of motors are built with 5mm 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 the 30mm 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-3020 series motors measures 5mm in diameter, and is 74.5mm in long. The shaft kit will also fit other brushless motors that require a 5mm 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.
