Morphing (mechanical) Airframe rotor disc control

Let me know what all of you think. I need your feedback.

Human Interface Rotor system helicopter (HIR) Patent Application number US 12,462,595 utlizing an in-flight reconfiguring or "morphing" airframe for rotor disc control. Charles Seibel could be considered the first to pioneer morphing airframes with "Human Interface" rotor control. Back in his hay day, the former Bell Helicopter engineer gone Cessna, designed a helicopter in which the cockpit could slide forward, aft and in lateral fashion thereby changing the center of gravity for directional control of a helicopter.

Finished most of the aluminum mockup. Moved the gimbal yoke more forward to tweak the CG.

98% complete with the lower airframe of the carbon fiber RC prototype. Replaced the aluminum gimbal yoke plates with CF plates.

First or second "rough frame" center of gravity hang test. Alot of changes since this stage. Bent the stainless steel rotor mast during the 1st power up. Used CP garde 5 titanium for mast now. Still tweaking

First attempt at a tethered flight did not go well for the carbon fiber prototype. Forward/aft thrust vector is spot on; some of the weight is too high on the frame......making modifications, Re-machining rotor mast; torsional flex developed causing vibrations.........videos posted on my web site.

Most of the parts are cut out of carbon fiber for the changes to the airframe. Trying to catch up.

I've been working with a frenzy trying to finish my wife's chair and end table along with my project. Got everything loosely put together yesterday and something on the bottom of the motor burnt out, but the motor still works. Some type of circular chip board on the base. Anyway, with the rotor hub loosely tweaked and no servo attachment, with 1/4 bat charge, the helo was lit on it's frame and stable. That surprised me because without the servo attached, the airframes can move forward and aft freely. Hope to have it going. Still need to tweak the hub assembly to tightend down the swah plate input control rods which serve no purpose no with out the swash,
