Scorpion HK-5025 Shaft Kit XL (6mm 44mm)

The Scorpion HK-5025 motors are built with 10mm 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-5025
series Scorpion Helicopter Motors.

The shaft for the HK-5020
series motors measures 10mm in diameter, and is 100.6mm 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 10mm 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.
