Thanks Dave - or is it D. Jakziowski? My Polish isn't so good, although i will soon be involved in some durability/fatigue testing in Czech Rep which is just next door...

Looking at your page, i'm hoping you can now easilly answer the "thoughts":

"Direction of rotation differs from all other intermeshing helicopters."

Inboard advance offers aero sideslip/yaw stability and gyro roll/yaw stability, outboard advance offers better aero efficiency...

"Static Stability might be affected by anhedral, resulting from the slope of the advancing blades. ???:"

Rotation direction will adversely affect stability, but a nice gyro stability aumented control system will make it flyable...

Remember the jury is still out on the Intermesher Vs Coaxial debate...
