That's a good point Eddie!
The Futaba version is optical, but not as fancy in the software dept as the FMA co-pilot.
I don't know about hovering a heli, but they can be set very aggressively and work well with fixed wing.
There was an article (I think in MAN) about somebody mounting one in a wing to hover and torque roll a .40 sized stunt plane.
"What's the worst that can happen...?"
