Same for RPM and battery voltage drop
Motor velocity konstant Kv (expressed in rpm/volt, it has a massive effect, cubed, on current and power drawn)

Note that Kv says nothing about max.continuous power, the motor in your toothbrush and the the motors in a 1:1 train can have same Kv.

With the above info you can try

Prettig weekend

Hi mate, the GA2000.4 is a 400KV unit. I didnt put a wattmeter on it but i was betting on it being higher that 2400watt. The ESC was sent back, I tried programming it for my purpose using the optional programmer box and it did the opposite when back in the model. Then it wouldnt even read the ESC when i tried to reprogram it. The whole power train is being replaced with a Tmotor AM670 combo. I will be staying well away from Hobbywing.
