The Scorpion HK-3014 motors shaft kit 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 HK-3014 series Scorpion Helicopter Motors.
The shaft for the HK-3014 series motors measures 5mm in diameter, and is 57mm in long. The shaft kit will also fit other brushless motors that require a 5mm shaft of this length. This shaft kit will work with the newer version HK-3014 motors that have the C-clip retainer, and it will also work with the older style motors that had the retaining collar with set screws. 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.
