I was just curious if there are any rc helicopters out there that are fixed-pitch that self-level like coax'es do. I imagine it would need some sort of gravity sensor gizmo attached to the body to calibrate aileron and elevator servo's. Anyone know if this actually exists or is it just a theoretical fantasy?

FMA has a [link=http://www.fmadirect.com/detail.htm?item=1489&section=1]Co-Pilot Flight Stabilization System [/link]. Someone else makes the same kind of system but I cant remember the name of it.

Do you know if that thing would work in a small heli (an 'Exceed Falcon 40' to be exact)?
