GUYS, need your help!

I have the EVSD-5U-PRO Multi-Function Valve installed in my MB339...and after some tinkering I have it working properly with one exception, and I dont know how to fix this issue.

The valve, by design, will always failsafe to the gear down position when you boot up the system regardless of where you have your gear switch.
This is to prevent acidental retraction of the gear if you boot with the switch in the wrong place. Nifty right? Not so much...


Here is the issue, if your gear is up and doors are stowed (like it would be when you assemble it at the field) and you service the air, when you boot the RX the gear is coming down NOW! The problem with that is the system does not bother to open the doors first. THIS IS A SERIOUS PROBLEM as it like to rip the doors right off your plane.

Would anyone out there have any idea on how to either get the system to open the doors first or how to disable the gear down on boot failsafe all together?

Any and all ideas welcome!

Thanks!

weird i have the same one and dont have this problem.
you sure it works the right direction?
can you use the brakes when retracted?(not disabled by RX)
the evu-pro does this itself..
also make sure if you use spektrum you rebind after you are done.

(my gear comes down when i switch it on without the TX BUT it opens the doors first.

i think you have the valves and doors reversed on the unit.
firtst you need to set those right THEN program the unit.
