I also consider a computer controlled aircraft to be - an aircraft .
This concept is also computer controlled ----
The CG -FYI, typically produces decent results over about the first 50% of the chord.
Tricky -yes -
Dick: the main issue here is about whether or not the CG location affects stability.
The answer for me is still - yes, it does.
A computer controlled full-scale fighter aircraft, as you mentioned above, is not stable enough to be controlled by the pilot alone.
It took full down elevator control and the flight path was anything but sedate BUT- it was flown to the ground-the model had big control surfaces and lots of throw.
we checked the CG -just to see what happens when a few lbs flies off the nose.
The CG was just AFT the trailing edge.
Your friend saved the model thanks to his skills and/or luck, as the model was not easy to fly in such circumstances due to the increased instability.
You might try being less judgemental and try something new - it really can be eye opening.
I really do like new things and new ideas, but one should not disregard basic physics principles.
