Thanks fellas - really appreciate the advice.
I was the nerdy kiwi kid who called the local Hughes dealer in the late 70's at age 8 - trying to understand how a swashplate worked.
He mailed me the multi-page spiral bound D-model marketing booklet that Hughes sent out back in the day - complete with cutaways and accompanied by the glossy brochure on colour schemes.
Within a few days I'd customised the meanest, high geared, full avionics specc'ed, Magnum PI'd coloured beast.
And once I saw the real thing swooping in to land at a local airshow, sounding like a big angry bumblebee and smelling of Jet A1 - I was hooked.
I'll let you know how I get on...
