Scorpion motors are built with 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 Scorpion Motors. The 22mm, 30mm and 40mm motor shaft kits include an original equipment factory shaft with the setscrew keyways already cut, a new shaft retaining collar, and a replacement setscrew for the retaining collar. The HK 22mm series shafts are retained by a setscrew at the can end and a circlip at the output shaft end.

Note: The shafts in all Scorpion motors are a slight press fit into the aluminium 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.

Spare shafts for the 22mm series motors measures 3mm in diameter, and varies in length for each motor.

The shaft kit will also fit other brushless motors that require a 3mm 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.

Spare shafts for the 30mm series motors measures 5mm in diameter, and varies in length for each motor.

The shaft kit will also fit other brushless motors that require a 3mm 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.

Spare shafts for the HK 22mm series motors measures 3mm diameter through the motor (except HK 2221 which is 4mm to cope with the high torque) and 3.17mm at the output end. The shafts in these kits are all 3mm externally to fit the popular pinion gears that are available.

HK motor shaft kits include an original equipment factory shaft with the setscrew keyway already cut, a new spacer washer, and a set of 3 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 a couple more to try again!

The shaft kit will also fit other brushless motors that require a 3mm 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.

Spare shafts for the 40mm series motors measures 6mm in diameter, and varies in length for each motor.

The shaft kit will also fit other brushless motors that require a 6mm 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.

All of the Scorpion 22mm motors include a cross style backplate mount, but occasionally, you need a spare or a replacement. The Scorpion Cross Mount is designed to fit the back of the Scorpion motors and provide a method for mounting the motor to a model's firewall. The Scorpion Stick Mount is designed to fit to the back of a 22mm motor and provide a mounting point to a 10mm or 3/8" square motor mount stick. All Scorpion mounts are made from strong aluminium alloy and finished in a durable and attractive black Electro-Coat finish. To finish off the look, the Scorpion Logo is laser engraved on the side of the mount to match your Scorpion Motor. The mount comes packaged with four 3mm machine screws to attach it to the back of your motor.

The 22mm mount weighs only 1.5 grams by itself, and with the 4 screws, it weighs 2.4 grams. The hole spacing on the back of the mount measures 16mm center to center in one direction, and 19mm center to center on the other. With this standard hole spacing, the Scorpion 22mm Cross mount will not only fit the Scorpion Motors, it wll also fit the GWS 22mm outrunners, the Hacker A20 series outrunners, the Waypoint 22mm Outrunners, the AXI 22mm outrunners, or any other motor with a 16 or 19mm hole spacing.

The mount weighs only 3.5 grams by itself, and with the 4 screws, it weighs 4.4 grams. The hole spacing on the back of the mount measures 16mm center to center on the vertical pair of holes, and 19mm center to center on the horizontal pair of holes. With this standard hole spacing, the Scorpion Stick mount will not only fit the Scorpion Motors, it wll also fit the GWS 22mm outrunners, the Hacker A20 series outrunners, the Waypoint 22mm Outrunners, the AXI 22mm outrunners or any other motor with a 16 or 19mm hole spacing.

This Prop-Saver Adapter is the same one that is included with 2205, 2208 and 2212 series Scorpion Brushless motors. Machined from high-quality aluminium bar stock, it is designed to fit on a 3mm motor shaft, and comes packaged with 2 rubber O-rings.

One side of the adapter has a tapered boss with a maximum diameter of 6mm and the other side has a tapered boss with a maximum diameter of 5.5mm. The Scorpion prop-saver adapter weighs 2.0 grams by itself, and 2.4 grams with one of the O-rings installed.

It can be used on any brushless motor with a 3mm shaft, and is recommended for use on motors of 200 watts or less. The O-rings are substantially stronger than those found on other prop saver products, but they are easily damaged by sharp prop edges. We recommend that you remove the sharp edge of the prop where the O-ring fits.

This threaded prop adapter is the same one that is included with 2205, 2208, 2212 and 2215 series Scorpion brushless motors. Machined from high-quality aluminium bar stock, it is designed to fit on a 3mm motor shaft, and has a 5mm threaded prop shaft. The Scorpion 3mm threaded prop adapter weighs 5.1 grams, and can be used on any brushless motor with a 3mm shaft.

This threaded prop adapter is the same one that is included with 3008, 3014, 3020, 3026 and 3032 series Scorpion brushless motors. Machined from high-quality aluminium bar stock, it is designed to fit on a 5mm motor shaft, and has a 6mm threaded prop shaft. The Scorpion 5mm threaded prop adapter weighs 8.8 grams, and can be used on any brushless motor with a 5mm shaft.

This Threaded Prop Adapter is the same one that is included with 4020, and 4025 series Scorpion Brushless motors. Machined from High-Quality Aluminum bar stock, it is designed to fit on a 6mm motor shaft, and has a 8mm threaded prop shaft. The prop shaft length is 33mm (1.30 inches) so there is plenty of room for a prop and spinner backplate. The Scorpion 6mm Threaded Prop Adapter weighs 22 grams, and can be used on any brushless motor with a 6mm shaft.
