HKII-2208 Shaft Kit
The Scorpion HK-22mm series of motors are built with 3mm 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.
The shaft for the HK-2208 series motors measures 4mm in diameter, and is 45.7mm in long. The pinion end of this shaft is ground down to 3.17 mm. 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. Also, these shafts are 3mm from end to end. The stock shafts are 3.175mm (1/8") on the output end, and 3mm where they go through the bearings. These shafts are offered for people that already have a large number of 3mm pinion gears, and want to swap the motor over to take 3mm pinions.
