RE: EVSD-5U-Pro Multi-Function Valve
Danno, I had a similar experience after landing. I thought my poor landing caused the gear to fold but now I'm beginning to believe the valve commanded gear up for some reason. When we picked the plane up, the gear came down and locked. Air pressure was not an issue. In fact if I had low pressure the gear would not have retracted since it failsafes down with low pressure. That was the beginning of my problem. Now the gear will not function at all except in the manual mode. I have plugged in a new harness, changed receivers, reprogramed the valve, re-bound the receiver and then plugged a servo into the gear port on the receiver to confirm that the receiver was sending a gear commands (signal confirmed). What I finally did was put the gear down and locked in the manual mode, dumped the pressure to below 50 psig (failsafe gear function level) and then went and flew. The gear stayed down. I'll be calling Todd to get the valve factory bench checked.
