Could it be similar to the Mayo One helicopter?
http://www.mayo.edu/mmt/mayoone_indepth.htm The one I saw refueling at
FRM last Sunday was a twin tail jet helicopter. Once it took off, it
got about 1/4 mile away and then couldn't be heard...

Several times over the last few months, I have heard what sounded
like a small bizz jet overhead, and gone outside only to find that it
is some
kind
of a helicopter. I can hear almost no rotor sounds, just the light
roar
of
a jet engine. The only distinguishing feature (to my eye) is that it
has two parallel vertical tail structures, kind of like on an A-10
Warthog,
but
very much smaller.

It looks like a normal commercial 'copter, other than that. Does
anyone know what kind it might be?



That's the one. Here is another picture from the Mayo One website

It looks sort of like the Hughes 600N

but the tail surfaces are graceful and finlike, not stubby.

Thanks,

ps. I want a Cartercopter.
