The Scorpion S-5535 series of motors are built with 8mm 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 55mm Scorpion Motors. Our Motor Shaft Kits include an original equipment factory shaft with a washer and a metric screw.
The shaft for the 5535 series airplane motors measures 8mm in diameter, and is 116 mm in long. The shaft kit will also fit other brushless motors that require a 8mm 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 metric screw 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.
