I would be interested in the breaking circuit that you said that someone has
posted in the past. 

 

The braking circuit is quite simple - all that is need is to close the motor
circuit to ground when you let off the switch.  Use a DP switch, or relay.

 

Even with the braking of the motor, I find it hard to trim at cruise for
level flight. A touch one way and it may slowly climb; a touch the other way
and it may slowly descend.  I'm looking for a circuit that connects to the
pitot pressure, and varies the motor speed with airspeed.
