Question about Amp draw

[BrianG]

Your friend is incorrect. The ESC puts out a PWM (varying pulse widths) voltage which is proportional to throttle setting. The more throttle, the wider the pulses. Narrow pulses sends lower average voltage to the motor, wider pulses sends higher average pulses to the motor. The motor will pull whatever current it needs to reach the rpm for that voltage, which is determined by the motor kv. So, if you gently throttle, current is low. Mash the throttle and the current is very high. Any eagletree graph will confirm this.
