Hi Guys,
That's an awesome vid and even my missus said she wouldn't mind flying if she could see scenery like that! (As long as she could use the mountainboard undercarriage take off technique (MUTT!))
I do have one slight concern,which is the over the water bit. I'd want some proper safety inflation kit installed to my rig if I was doing that flight!
Propellor wise, the Merlin and later variants of the Lynx helicopters utilise BURP technology to provide amore efficient lift/thrust and later varients of the Hercules C130 have some funny twists in their propellors, presumably for the same reason.
On a geologic theme, can you see the different levels of strata in the cliffs? V. V. Nice. There's so much you can get from this hobby apart from the flying itself!
Cheers all
Tj
