HKII-4225 Shaft Kit (6mm 37mm)

[HKII_4225_shaft]

Price: $33.50

In stock

The Scorpion HKII-4225 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 HK-4225 series Scorpion Helicopter Motors.

The shaft for the HKII-4225 series motors measures 8mm in diameter, and is 92.2mm in long. The pinion end of this shaft is ground down to 6mm to allow the user to install 6mm pinion gears. 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 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.

Remark: This shaft is compatible with both Scorpion HK-4225 and HKII-4225 motor series
