Product overview
The Scorpion HK-4530 Shaft Kit XL (6mm 55mm) is a motor repair component supplied as a factory replacement shaft kit for the HK-4530 and HKII-4530 helicopter motor series. It addresses replacement of a bent or broken shaft. The hardened steel shaft has an extended configuration: its main diameter is 10mm and its overall length is 117mm. A reduced, ground 6mm end provides the interface for 6mm pinion gears, making both the main shaft dimensions and pinion bore relevant to integration.
Fit extends to other brushless motors requiring a 10mm shaft of this length; shortening with a Dremel and cut-off wheel is possible when another motor requires it. Removal from Scorpion motors involves a specific mechanical constraint: the aluminum front housing grips the shaft with a slight press fit, so releasing the setscrews is insufficient. A bearing press or drill press must push the shaft out while a wooden block supports the housing against warping. The stated 82g weight includes packaging.
