Hi Edison,
The unit is plumbed exactly like the instructions. I believe i am supposed to set the valve sequence in the advanced mode but there is no step or order in what i am supposed to do first or last or whatever [:@] I just want the doors open with gear down, gear up doors close etc. The brakes work fine and the air pressure and other features are good too. When i switch the retrac lever the door 2 valve that i am not using cycles first, the door 1 cycles and then the gear move up very slowly, all out of time?? ugh... i fiddled with this for hours today. I hope you can tell me exactly what to do with it. I don`t feel too bad my friend Jim Mcewen who is an aerospace engineer gave up on it too...[]
