G'Day Sky Gazer,
Adrian Stofells can shed a lot more light on the subject.
Big, roomy, good visability and heavy.
Kevin Traeger had something to do with refitting one to I believe. He told me they were slippery as!
I have seen video footage and it looks the 'ducks nut'.
However, I was interested 5 years ago and not many out there in that time. Had probs getting them to fly right initially. There were a couple fyling in OZ. One is no longer ( we lost a good bloke in Chris) and one is in Adrians 'Skunk works" aviation laboratory

. There may be others in Oz but not many.
There is a Dealer for them in the US no Doc something or other, check the US forum. They call then UFO Defenders I think over there. And Last time I quizzed Doc he said they fly great now.
Adrian is refitting one in West OZ.
I hope the claimed figures are all they should be, I know the designer Mac has been trying to get it all sorted for many years now.
Cheers,
Mitch
