Dear Boys and Girls, here is an article in French about the Monte-Copter Model 15 Tri-phibian amphibious helicopter prototype which had a cold-cycle rotor......

The article comes from the 6th January 1961 issue of Les Ailes......

Looks like something Disney's Imagineers dreamed up to go with the monorail...
 
A bad scan but interesting info:

Maurice Ramme, a founder of the American Helicopter Society and the 87th licensed commercial pilot in the United States, died in December 1995. His helicopter experience began in 1948 when he served as test pilot for Hoppi Copter in Seattle.
There he tested and promoted a counter rotating, one man, back pack helicopter which looked like something out of "Buck Rogers." Mr. Ramme also tested Hoppi's one man, tricyc1e landing gear) counter rotating helicopter which was the forerunner of many of today's ultra light machines. While teaching turbine theory at Edison TechniCal Institute he learned that gas turbine air might be used to power a helicopter. In 1953, Mr. Ramme formed MonteCopter, Inc. to develop one of the first air driven rotor helicopters in the
United States. His prototypes include the Model 10, the first helicopter to fly using boundary layer slots as the only means of propelling the rotors, the Model 12, the first twin turbine pressure jet helicopter in the U.S., and the Model 15 Triphibian, capable of operating on land, sea or in the air.

When I joined Trident Aircraft at Victoria, BC in 1976 the hulk of the Monte-Copter Model 15 was stored in a corner of our hanger at Victoria International Airport. We shared the hanger with an elderly gentleman who rebuilt wrecked light aircraft, and he told me that he in turn had rented storage space to a Canadian company that owned the design rights. He gave me a phone number of the company, but the number had been disconnected (I wanted to send them a resume ;D). The hulk left the building one weekend about a year later.

From memory, it was just a fibreglass shell, with no engine or rotors. I think it was a very faded pink and white, may have been red and white at one time. I regret that I never took any photos of it at the time.

Perhaps a photo editing demigod might want to correct the faded colors? ;)

The "Model 14" seen here was actually the earlier Model 10A prototype before it was rebuilt into the Model 12.
