Revolution Helicopter’s Mini 500 Kit Helicopter

FINALLY, A NEW HELICOPTER YOU CAN AFFORD!!!

The first new Mini-500 shown in the photograph nearing completion, was pulled off the production line and displayed at the 1991 EAA Fly-In in Oshkosh, Wisconsin.

“We just made out 52nd sale and many of these customers should expect to receive their aircraft sometime by the end of this year,” said Dennis Fetter, chief designer and president at Revolution Helicopter Corp.

“The interest in the aircraft has been overwhelming!”, Fetters said. “Although RHC anticipates an extremely large domestic market, surprisingly, two thirds of its advance sales have been overseas”, said Fetters.

RHC makes the Mini-500 affordable and practical for almost anyone to own their own helicopter. Before, it was impractical because of the tremendous expense involved in operating and maintaining a helicopter.

“The total design spectrum of the Mini-500 is a one-man utility and sport aircraft providing true helicopter capabilities and performance”, Fetters said.

The Mini-500 is inherently more stable than helicopters of its type primarily because of the new patent pending control system. The use of this machine is only limited by one’s imagination! Already inquiries and purchases have been made for recreation, commuting, agricultural, medical, traffic and border patrol, among others.
