George,

Ours are about three weeks old from Todd. Mode 1, it works fine, mode 2, like Dave said, it wants to held the doors shut and blow the gear open. Bad combination. I agree with you George, this is something that should be able to be updated through software, or maybe we're all just idiots and it is a simple programming feature. (The latter is certainly possible on this end).

Great valve, but this little quirk can be annoying, especially on a plane like the 339 where the doors really need to shut after the gear is down.
