Scorpion HKII-4235-630kv Shaft Kit XL (6mm 50mm)
Sorry, this product is temporarily out of stock.
The Scorpion HK-4235-630kv shaft kit XL (6mm 50mm) is built with 6mm 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 HKII-4235-630kv Shaft Kit XL (6mm 50mm) for Scorpion HKII-4235-630KV (Limited Edition) motor use.
This extended shaft for the HK-4235 series motors measures 8mm in diameter, and is 112.9mm 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 set screws 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.
