Geistware.....
I know what you mean.....on my little itty bitty 81" Air Wild Edge (compared to those guys yesterday) I have 60 degrees of throw on the elevators. I only use them during slow, high alpha type flying. I have a lot of expo (85 %) as well.....very little input is needed and can get to be a real handful quick. It is rock solid in elevators and harriers with no spolier type of programming.
I'd suggest getting a Edge to learn the 3D type of flying. Nothing does it better. I'd be concered with trying it with the Giles......but that is just me.
