Scorpion HK-30 Bearing Kit

The Scorpion HK-3026 motors are built with 5mm 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 repalcement shafts for all the HK-3026 series Scorpion Helicopter Motors. Our Motor Shaft Kits include an original equipment factory shaft with the setscrew keyways already cut, a new spacer washer, and a set of 2 retaining clips. This way, when one goes flying and bounces off the wall while you are trying to install it, never to be found again, you still have another one to try again!

The shaft for the HK-3026 series motors measures 5mm in diameter, and is 74mm in long. The shaft kit will also fit other brushless motors that require a 5mm shaft of this length. This shaft kit will work with the newer version HK-3026 motors that have the C-clip retainer, and it will also work with the older style motors that had the retaining collar with set screws. 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 houshing of the motor supported in a block of wood to prevent warping the front housing.
