I have mentioned this before, but I very much DISLIKE the robart valve with needles. I have had several and they all have failed even after I had messed with them to get the needles set. Eventually, some minute vibration or jiggle makes the needles somehow either leak the air all out or close off the air so the gear wont deploy. This happened on my ESM me-110.
The 110 isn't the only plane Ive had that problem occur on using the robart red valve with needles.
I will no longer use them. Instead, I use the robart blue colored valve and then install air restrictors in the air lines. Those restrictors are NOT a failure point. The gear retract and deploy at a scale speed every time and there is no possibility of a needle bleeding the air out or choking it off.
Im sure there are people that have nothing but success with the red valves, but as VG is fond of saying......"failure point" is front and center on that design.
