Mike Blandford Posted October 19, 2021 Share Posted October 19, 2021 While the equations are valid when all you have is a resistance, an electric motor (brushed or brushless) is NOT just a resistor, it actually has inductance (coil of wire) as well as the back emf due to rotation. Quite simply, if all the power from your battery is being converted to heat then your motor will rotate perfectly OK and drive the propeller without needing the battery, so just take the battery out and go flying!

john stones 1 - Moderator Posted October 19, 2021 Share Posted October 19, 2021 I think we can safely say the O.P has had the question answered, and an informative debate about Wattmeters for good measure. We are going to close the thread now gents, it seems to have run it course. 1 3 Link to comment Share on other sites More sharing options...
