The 'RAIDEN' motor is designed and produced by My3dbase, a German company that design and build some awesome 3D printed blasters. These motors were specifically designed to work with their blasters which are based on small flywheel designs. Similar in performance to the Merlin motors from FTW, the high spindle speed of these little powerhouses is optimised for small flywheels such as Worker Hurricane wheels. On a 3S the RAIDEN motors have a spindle speed of around 74000 rpm delivering 800gcm of torque . With neodymium magnets, dual ball bearings and large venting holes, these new motors provide everything we have come to expect from high performance nerf motors. Price is for 1 motor.
