RE: watt meter
So far, I put connectors on it, plugged it between the battery and the ESC. Did a run up, it showed the watts and amps. There is a button on it, that will hold the readings as long as it is plugged into the battery. That is about it. It is SIMPLE!!! I am more interested in not melting my ESC then a complete recording of the power used during a flight.
I will work on getting a few pictures of it in use.
