WHOs THIS

Its rudder has a very low effect, not only because of the small surface area, but also because extended by the fuselage over almost the entire height, the center of pressure is moved very far in front of the hinge. Unfortunate effect discovered around 1927 on Couzinet aircraft


In spite of this, the designer could have placed the passenger's feet under the heavy engine, and the pilot's feet on either side of the passenger's buttocks. This could help to reduce the yaw inertia

The tank located far in front of the center of thrust of the rotor would probably have significantly modified the pitch balance depending on the remaining amount .

Twin rudders on a larger horizontal stab would have helped

I believe the guy in the video wrote for Kitplanes. He did an article on the build and flight. He said he thought the axle tubing was too light so he used solid rod. The solid rod didn’t weld well to the tubing cluster. It broke away during testing causing the gyro to roll over.
