Draws over 12 watts just to hold the clutch in. It gets crazy hot. I'm down to about 1.5 watts to hold.
As an alternative can just put resistor and capacitor in parallel in series with the clutch. That will get down to about 4 watts, mostly dissipated by the resistor.
Pierre you may want to just buy the new motor controller with the clutch output and rudder position. It's pretty reasonably priced.
I'm thinking of buying a new one to make my setup simpler.

The newest motor.ino codes support pwm on the clutch output, and the duty cycle is configurable in the pypilot settings. So it does apply full power to the clutch for a few hundred milliseconds, but after reduces to pwm with set duty cycle to drop power.
