HKII-2208-3.17mm Shaft Kit
Scorpion HK-2208 3.17mm Motor Shaft Kit
The Scorpion HK-2208 motors are built with 4mm 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-22mm Scorpion Motors. Our Motor Shaft Kits include an original equipment factory shaft with the setscrew keyways already cut, a new spacer washer, and a set of 2 retaining clips. This way, when one goes flying and bounces off the wall while you are trying to install it, never to be found again, you still have another one to try again!

The shaft for the HK-2208 series motors measures 4mm in diameter, and is 45.7mm in long. The output end of the shaft is ground down to a 3.17mm diameter to fit the popular pinion gears that are available. The shaft kit will also fit other brushless motors that require a 4mm 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. 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.
