December 2, 2016Application(s): These servos are unlike the typical servo, they have Properly Shimed Helical Gears. These servos have Ball Bearing inside. My servo stopped working but the mounts were still good, so i pulled the gears and stuck them into a ha-422 that had broken mounts from a an old crash... just letting you know that this works the helical gears fit into a 422.
Comments: Being that I have servos that could just about break this servo in half... i give it a 4 because of the cool helical gearing.
