Tethering at low power settings, getting use to response to throttle and cyclic rotor movement at low power, low power means not enough to make the aircraft light, sure ok.Thanks so much for sharing your research. Questions are being answered that I haven't been able to find answers to, its brilliant!
So it seems I can expect high instability going from ground to hover but once in hover things might get easier. Thinking about it I have experienced this to some degree in a rc model, the transition from ground to hover is always a bit sketchy, then it stabilizes further away from the ground.
I reckon a dynamic roll over with the helitrike would be a major problem with so much weight so high.
Interesting thought on the offset hinge I don't know much about this but looking at the air scooter and Nolan designs I can't work out if they had offset hinges.
on your weight shift machine, is the pilot seat suspended from a single chord like a hanglider?
I need to decide how best to tether the craft to try and make testing as safe as possible. If I ever experienced a dynamic roll over and walked away I think it would be the last time I went near the machine. Its tether versus long poles bolted to the skids or I make some sort of telescopic platform?
Power settings enough to lift the aircraft the tether has pluses and minuses.
Plus, too much lift response whether due to throttle or sudden wind - keeps you from finding yourself way up in the sky.
Minus, if you drift, and you will drift, one tether pulling tight will result in a off center vector you can not respond to, dynamic roll over.
Tethers that are longer say 4 to 5 ft long are ok, just as long as you don't get more than 1 foot off the ground and preferably attached to the aircraft at 4 equal box forming to the aircraft, each tether extends to make an x that would make line through the center of gravity, so no matter which way you drift 2 or more tethers should equally pull on the aircraft and hopefully stop the aircraft without tipping it.
Also training poles that go thru your landing skids that form an x in the center of the landing gear and extend to the total of the diameter of your rotor system will also kind of push your aircraft back to level it you tilt too much in any direction as long as you are less than a 2 ft hover and the aluminum tubes have sufficient wall thickness.
