Are the engines scaled-down RB211s or what? What fuel do they burn?

You can buy very small jet engines these days.
Same technology as cruise missiles.

I have yet to see a stealth fighter model (not that i have looked
much), they can only fly by wire as they are unstable.

easily fixed by moving the CG forward enough.

I have never thought about that. Was it moved back, or forwards?
And I spent 21 years working on this. :-(

Forwards.

I feel thick now, knowing that. Hence the canards at the front being the

canards at the front require a very forward CG, or if you think of them
as aircraft with very large tails. a very rearward one ;-)
