fly-by-wire
Does anybody know of a fully fly-by-wire helicopter out there? (Or know anything about the development of one?) I've heard that BAE is developing one from a friend, and I just want to know if its been done before...

Aser is correct, but there is FBW and then there is real FBW. The NH-90 has a FBW system, although it has two digital lanes and two analog lanes, so it can only do what an analog computer can do (basic damping and such).
The Comanche system was fully digital, and had advanced sensors and control laws that changed the way the controls work. Literally, the aircraft flew with groundspeed control and the stick was used to command more speed. Big change from attitude control as we are all used to it (and as NH-90 still has). Non-pilots could fly Comanche while doing precise hover and target enganement maneuvers, and little outside reference was necessary.

Here's another V-22 fly-by-wire
As HOSS 1 says;
"You didn't mention it had to be manned !"
______________ Edit ______________
A little more serious;
FBW for the S-92

And, if we are counting UAVs, there is also the Northrup Grumman Firescout. I think the airframe is built around Schweizer 333 components.
