Scorpion HK-2221 Motor Shaft Kit (FORZA450)

Product Description

The Scorpion HK-2221 Motor Shaft Kit (FORZA450) 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-2221 and HK-2520 series Scorpion Helicopter Motors to fit JR Forza use only.

The shaft for the JR Forza 450 measures 5mm in diameter, and is 59mm in long. The shaft kit will also fit other brushless motors that require a 4mm shaft of this length. This shaft kit will work with the all HK-2221 and HK-2520 motors that don't need the C-clip retainer.

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.
