Homebuilt Helicopter From Michigan
Ultralight helicopter project with fenestron, Michigan
Experimental Twin Engine Helicopter project for ambitious person with engineering and fabrication abilities.
Most of what you need to finish is included however no gauges are provided and you will have to design and build gearbox enclosures for engines and transmission.
Blade molds are included to make fiberglass rotor blades and engines are Suzuki TL1000. Mazda Rotary parts and separate transmission is included from earlier design. Almost everything is carbon fiber and titanium.
Twin engine design uses two Suzuki TL1000 engine upper ends with BMW crankshafts. The planetary gears from a Chrysler automatic transmission gives a 2:1 instant choice of 9,000 rpm or 4,500 rpm.
If a engine should fail you can instantly shift the speed of the remaining engine from 4,500 cruising rpm to 9,000 rpm to maintain altitude. By stopping the outer shell rotation of the planetary gear does the shifting.
