I never even intimated that the planes were more stable - really -
My whole thought was that as one reaches for zero wingloading - the CG becomes less critical - I called it less important and of no importance at all in some instances.
I can't prove anything with a calculation on this -and no one has ventured a relevant calculation against the thought.
Why even bother .
I did say I thought the plane would be flyable at "zero" wingloading (weighing nothing).
It is a whimsical thought sure - but I see no reason it would not fly ---with constant corrections of course .
I see thrust becoming the all important factor in the equasion and lift reduced to zero importance. (nothing to lift.)
BUT - the surfaces would still be used --to control flight directiuon.
Now call it an airplane - call it an elephant - I don't care -
it is heavier than air (one 1/100 of a gram is till a +) and is powered.
For damn sure it is NOT a conventional airplane - I never intimated that either .
good fun tho ---
