Got Inspire 1 X3 to work with Osmo but...

update on my handle with x3....If i put slight downward press on the x3 into the handle and turn the handle a little harder than a young girl, BEHOLD!....it does turn fully and lock....im so excited
 
+1, my inspire x3 fits fine and after upgrading firmware (bird first) I was good to go and super solid mount on the handle
 
Two firmware upgrades. 1.6 while on the bird then move the camera, replace the chip with the latest Cosmo firmware then it takes a few minutes and your camera will spring to life (you might lose wifi connection so be sure to check that) Good luck
