Team Epic motor dyno
Team Epic have released this 7.4v powered motor dyno that allows you to test brushless motors with out the need of hooking up a speed control. Gives you KV, RPM and amp draw at user set voltage input and there is a mode for testing the function of the sensor to make sure it is functioning correctly. Runs off a standard 7.4V LiPo battery pack, so no big power supply is needed and it is small light and easy to transport to and from the track.
