Thanks for the information. The question is an attempt to get a better understanding of the coaxial, and perhaps the intermeshing, helicopter.
The pedal actions are reversed in a coaxial helicopter during autorotation. Apparently, the Kamov helicopters do this mechanically, so that the pilot does not have to think about 'which pedal does what' during this emergency. I assume that this mechanical changeover is the result of the position of the collective lever. This would mean that the yaw during the descent is quite conventional.
The interesting part would appear to be the landing, when the pilot is raising the collective to use the inertia of the rotors. If pedal was being applied while the collective was being raised, then the pilot would temporarily loose yaw control as the collective passed through this changeover zone.
Any thoughts?
