HKIII-4025 shaft kit 5mm
The Scorpion HK-4025, HKIII-4025 series 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-4025, HKIII-4025 series Scorpion Helicopter Motors.
This shaft kit is for the HK-4025, HKIII-4025series motors that used in newer T-600 Heli. It measures 8mm in diameter, and is 84.9mm in length. The pinion end of this shaft is ground down to 5mm to allow the user to install 5mm pinion gears. The shaft kit will also fit other brushless motors that require a 5mm 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.
