I have been on the cusp of buying into the Spreading Virgin... er... sorry... Wings/WKM/Zenmuse combo (peculiar fluffy romantic asian names !!) but these disappearing act stories, plus the fact that I actually witnessed the Flip Of Death in Atlanta last week, have really put a damper on it. Trouble is, I want another 'A' machine so that the AD-8 can become a proven, reliable backup. After witnessing the FOD we watched a newbie lift his S800/Z15/GH2 rig off the ground for the first time. Incredible video right off the bat on his first flight.
When its working it works really well. But what a horrible uncomfortable feeling, just waiting for it to unexpectedly go mad in two weeks/six months/three days/one month...
