Another weight shift helicopter.  The idea has been around since
Lilienthal

They did a good job on this one.

"Otto Lilienthal (23 May 1848 – 10 August 1896) was a German pioneer
of aviation  who became known as the /Glider King He was the first
person to make well-documented, repeated, successful gliding flights
Newspapers and magazines published photographs of Lilienthal gliding,
favorably influencing public and scientific opinion about the
possibility of flying machines becoming practical. On August 9, 1896,
his glider stalled and he was unable to regain control. Falling from
about 15 m (50 ft), he broke his neck and died the next day, 10
August, 1896."

I used the idea on my tilt rotor VTOL.

The weight shift helicopter was originally done back in the 70s by Igor Benson, the same Benson who invented the small home-built gyrocopter.

It was called the bensen zipster, small coaxial tilt head just like his gyrocopters were. It was powered by a water cooled outboard motor from a boat. Used throttle to increase lift for ascending or descending, and a tilt head just like all gyrocopters use. It used a longer top loader and a smaller bottom rotor and Incorporated and limited slip differential to turn them into different directions thereby cancelling torque. It also used disk brake assemblies on the upper and lower motor systems separate to apply torque to rotate the airframe and yell while hovering.

Both the air scooter and the Nolan Brothers Eagles Perch helicopter are just modifications on Benson's original design. Benson's Zipster  also in both of those cases that followed never really went anywhere because if you can't auto rotate the engine quits you crash.
