Extension has only gravity and the spring to extend and lock,
take the help from gravity away and the system won,t work properly.
I know nothing about the Robart copies but I have two sets of Springairs on my Wing P-38's and they are wonderful systems. But they cannot function properly inverted. Flip your airplane over so the gear can work as designed.

I agree. When testing on the bench, sometimes when the plane is upsidedown, they don't lock. If they work right side up, I wouldn't worry about it.
