well flingwing,
I'll have to read your post a couple of times for it to sink in, but I get the jist of it.
I know from MS Flight Sim that helicopters are extremely "touchy"...don't know if that's the case in real life...or to what extent it is...but I get the general feeling that it is.
I've been on a helo once...it was a ride when I went skiing in the Alps...it was very amazing...just felt very wrong...not having wings stickign from the sides...and wondering how forward movement was kept...
the guy literally seemed to not move the cyclic...
I can't wait to try this out...might happen after tomorrow if the weather permits me flying TO the airport where the helis fly...as I don't have a drivers licence

I just re-read your post and have a couple comments/qeustions
In the R.22, what happens is the tail rotor (still producing thrust) starts to roll the airframe to the right pretty quickly, while the rotor disk does not roll!
Now how exactly does the tail-rotor
roll the helicopter? I thought the tail rotor only affected yaw...isn't the rotor right about the center of mass of the helicopter so it would not really produce any rolling moments? It would have to be higher or lower than the center of mass to cause a roll.
And when you push the cyclic forward, the disk is unloaded cause...you gain airspeed which helps the engine rotate the rotor?
And about the RPM/stall phenomenon...
does that have to do with the picth from the collective which causes variations in RPM (due to drag and load on the engine)...
so say youa re at 104% Ng (RRPM and engine RPM)...so you are good...you are hovering with a certain pitch on the blades (certain collective).
Now say all of a sudden you want to climb...pretty rapidly...so you increase collective...and thus all your blade rotors' pitch increases...they take a bigger bite from the air...inrease drag, increase lift.
Now increased drag means higher load on th engine which was at 104%...now say it dropped to 90% due to the load...the engine is loaded...
Now does this mean you can't possibly increase the Ng back to 104% anymore? or anymore than 90%? due to the drag from the pitch of the blades? So the engine can't do it anymore?
So obviously if this is the case...there is a limit, like you said maybe 80% where the RPM is very low...and the engine cant' take it anymore...
the thing is, I would think small pitch, 104% would produce same lift as 90% and larger pitch...
so I'm still a little confused I guess
