Engineer and rotorcraft enthusiast Cameron Carter finally realized his dream of building and flying his own helicopter. This dedicated New Zealander has spent 12 years engineering this complicated personal flying machine.
He sought a project that involved solving all the problems that the pioneers of aviation had to solve. One of his biggest motivations was proving he could do it to all who thought it couldn’t be done. In his videos you can see him working to solve problems of radiator pressure, thermal siphoning, and eliminating overheating after shutdown.

He solved the load to lift problem by selecting the right engine for the job, a V4 common to 1970’s two seat helicopters. The engine is a two stroke approximately 1600cc, weighs about 100lb and has high power to weight ratio (140 horsepower at the flywheel). In a discussion on his YouTube channel he explains how he discovered that running 5000 RPM makes the best of the engine’s torque curve. He only used 46 horsepower to hover at ground effect (one rotor blade’s diameter from the ground). Unfortunately, flying any higher has met with a serious obstacle. The problem isn’t engineering, it’s the time and money required to meet the standards of aviation regulation.
Sadly, Cameron explains on his YouTube channel that the civil aviation authority strongly advised him to discontinue the project. He said “ It has been an very interesting challenge and has taught me a lot of different skills and process.” Ultimately, Cameron has demonstrated the perseverance and know how required to build a flying machine from scratch, a worthy accomplishment!
