He has a set for sale. timothy.ong@leadingedgeaircraft.c= om=20 Before you buy a new controller, I would remove the cover from the pressure= head, turn the rate on the controller to max, and change the altitude. If= the motor is turning the gears (it will be going very slow) then the contr= oller is probably working and the problem is the pressure head. Note that = there may be a time delay before it starts moving. =20 All the controller does is turn a motor on the pressure head that moves a b= ellows pressure valve in and out, and the controller senses the position of= the bellows through a 3 wire potentiometer that is geared to the motor. T= he controller has no idea whether the pressure head is actually doing anyth= ing. It only knows that the motor controlling the bellows is moving when i= t commands it to move. Pete
