Windspire Aeros


The Aeros is a Single Seat homebuilt helicopter. The plans manual offers pages of highly detailed construction prints, photos and assembly instructions to guide the builder.

This single-seat helicopter can be built in a well-equipped home shop. It features a bolt-together main frame and a standard helicopter control system: full collective with a twist-grip throttle, full cyclic and foot-operated tailrotor pedals. For low-cost and reliability, the drive train utiliizes a converted VW car engine and a primary belt drive that leads to a geared transmission with VW gears. The belt-driven tailrotor is high-mounted to minimize the rolling moment caused by tailrotor thrust. A number of weight-saving features have gone into the design Aeros, including a simple, but attractive monocoque tailboom. The Aeros is licensed as an Experimental Aircraft.
The Guidebook covers, with clear, illustrated explanations, how helicopters work, the various considerations that go into their design, main and tailrotor aerodynamics, control-system operation, and a glossary of terms. Then, fully illustrated with photos and detailed specifications, is a presentation of what is currently available to the helicopter hobbyist in the form of kits and plans. A comprehensive list includes sources of engines, metals, AN hardware, cables, controls, rotorblades, instruments, and the regulations you need to know.

The Aeros is capable of vertical take-offs and landings; hovering; forward, backward and sideward flight. In the event of engine failure, the Aeros can autorotate to a safe landing.
