Zenmuse Z3 does it work on Inspire 1 V1?

Took it out the other day, and it began to drop transmission, this is crazy...4K is the S/&!$
 
Any logical reason that the Z3 is only available through DJI's store with their prime dealers having no information as to when they will be available through them? Possible redesign of some sort before general release? You would think DJI would be forthcoming to their dealers with some sort of information.
 
I believe Ralph @FlyHighUSA has had them in for a while!
