RE: I have problems with my Air Power EVSD-5U-PRO-ST
I have yet a "New" problem with our valve in the Bandit.
What is happening is on the first retraction of the gear after the system is booted up, it retracts the gear and then continues to dump air until the fail safe value is reached and then it drops the gear and stops dumping air.
We found this on the very first flight of the Bandit as the gear went in the well and dropped again a few seconds later.
What we have found is that if you re-service the air without rebooting the system the valve works perfectly. So we now follow this procedure until we can get a replacement valve:
Service air - boot system - on a stand, retract gear and allow system to bleed down and drop the gear via fail safe setting - re-service air test cycle gear again for proper operation - re-service again - go fly.
At no time do we ever shut off the system or we have to complete the above steps again.
We will be requesting a new replacement valve.
