A PPLs perspective
A year or so ago the Danish airforce were off loading a bunch of H500s with heaps of spares. There were lots of rumors down here in Oz 'bout how you wouldn't touch 'em with a barge pole 'cause they wouldn't be certifiable in Australia. Everyone spoke like it was black & white, an open & shut case.
But there is at least one ex Kiowa with proper VH reg flying around down here. The owner runs it in the experimental class. As near as I can see he has the best of both worlds. He can modify the console to fit a mobile phone or whatever without all that TSO drama & the VH reg means he can fly it anywhere.
