I too loved flying Dean's Iroquois and also the one that Jordan (someone) had on Hovercontrol. The FU24 Fletcher was great too.
Flying a heli seems very much like balancing one ball on top of another. A blend of chaos theory and Newtons laws.
I did get a few opportunities to control a Bell Jet Ranger. operated by a mate. It was relatively easy in normal forward flight but hovering became an aviation rodeo display.
After it being suggested that I just think about moving the cyclic rather than actually moving it things improved greatly. Then of course we had to deal with the yaw and collective axis'.
Flying radio controlled helis was another challenge but made easier after having a bit of real world knowledge and a good RC simulator program.
