Experimental Helicopter Design

The "experimental helicopter" has continued to evolve through individuals creative interpretations of how the perfect helicopter should be. Engines, rotor blades and the fuselage vary to provide many possibilities and capabilities.


Some start as backyard projects or conversions of existing helicopters. We are fortunate to have those that dream the dream and live the reality of bringining us these new and innovative designs.

Aeris Naviter AN-2 Enara

Coaxial configuration two seat helicopter design project amd AeroQuad project flying platform.

Coaxial designs continue to appear across the market displaying various different design improvements.

BUG Homebuilt Helicopter

A series of homebuilt helicopters designed as testbeds for proof-of-concept helicopter construction.

Applying different techniques por powering and drive mechanics along with an innovative "Rotor Ring" main rotor blade idea.

The Dusty Helicopter

Another great experimental chopper from the USA, the Dusty helicopter.

Combining a bolt-together airframe and Mazda Rotary engine for plenty of power.

The GEN H-4 Personal Coaxial Helicopter

A unique minimal, multi engine personal helicopter. While innovative by design, it has never quite found it's market amongst the public.

An interesting concept that needs to prove it's practicality.

The KISS 209M Helicopter

The two seat turbine powered KISS 209M helicopter. Smart by desin, smart by performance.

Turbine power with optional retractable landing gear improves speed and performance giving sleek looks similar to the Dauphin helicopters.

The MC-1 Helicopter

The single seat MC-1 helicopter is a great little helicopter though little is known about it.

I've seen it powered by both two stroke (Rotax) and four strokes (Subaru EA81).

The NEO "NOTAR" Helicopter

The new generation "NOTAR" (NO-TAil-Rotor) rotary powered kit helicopter. Experimenting with the mazda rotary engine has allowed the potential of this no-tail-rotor design.

Though the mazda is heavy there are now aftermarket alloy side-housings that dramatically reduce weight. Maybe a future option for the NEO!

The RI 30 Eaglet "Dual Rotor" Helicopter

The patent pending dual-rotor-system provides maneuverability and performance, together with the best efficiency on the market.

Rotax 914 turbo power mounted in a similar position to commercial helicopters is a novel idea. Great looking with superb performance.

The SKYe SH09 Helicopter

The next Generation of multi-purpose light single-engine helicopter. While more on the commercial side of helicopters, it origins were no different to most of the kit and homebuilt designs.

A smart looking chopper with the potential of performance to equal today's best commercial choppers.

Unicopter Helicopter Project

The Intermeshing, Interleaving and PropRotor configurations helicopter design project. A massive source of information with formulae, specs and many design considerations and references.

While you could spend weeks browsing the large amount of useful information here, the basic concept is the same, to practically build what you can dream!
