I had an unusual kit when I was younger, and unfortunatly no longer have it. I will describe it as best I can, maybe someone can identify it.
I know it was used in Vietnam its main use as a rescue operation. The body was very boxy and it had two rotors on top side-by-side that angled outwards to each side and counter rotated withthin the arc of the other, the blades being spaced 90 degrees off from each other.A twin boom extended from the back with a tail plane connecting the two and a verticle stablizer on each side. A large round duct ran from the engine to the rear boom where the exhaust angled towards the ground at the end. The back had a rounded set of clam shell doors and a sliding door on the right side had a hoist above. I seem to recall it having 4 wheels for landing gear that had some sort of skids or ski looking plates the wheels extended through...
I tried searching on the net, but without knowing what it was I couldn't find much. I regret tossing it out as a kid. I loved that model as it was so unusual looking.
Thanks if you can tell me what it was and maybe some photos would be great!
