Scorpion HK-5035 Motor Shaft Kit 6mm

In Stock


The Scorpion HK-5035 motors are built with 10mm 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-5035 series Scorpion Helicopter Motors.

The shaft for the HK-5035 series motors measures 10mm in diameter where it goes through the motor, and is 116.5mm long overall. The pinion end of this shaft is ground down to 6mm to allow the user to install 6mm pinion gears. The tapered part of the shaft extends 49mm from the mounting face of the motor so you have extra length to go through the pinion gear and support the tip of the shaft with an extra bearing. The shaft kit will also fit other brushless motors that require a 10mm 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 Scorpion motors are a 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. Never tap the shaft out with a hammer. The shock induced can bend the motor parts and knock the glue joints loose on the motor magnets.
