In order to keep your motor in top running condition, you occasionally have to take it apart for cleaning, or to install new bearings. The Scorpion HK-series Helicopter Motors are held together with a spring steel C-Clip, and have a wave washer under the clip to maintain proper bearing tension. Every once in a while, when you are taking apart your motor, the C-Clip goes flying off, never to be seen again, or you drop it on the floor and simply cannot find it. For these times we offer the Scorpion C-Clip Kits. This kit is designed to be used with all the Scorpion HK-45 motors and contains 4 new 10mm C-Clips, 4 new 10mm wave washers and 4 of the set screws that are used to lock the motor shaft into place. It is a good idea to keep one of these kits in your shop for each size motor, just in case you ever need one!
