It was Nick who said the increase in AOA on the stabiliser would make the nose go down.
Crab,

Yes, It was indeed...but I think he was just being sloppy and really meant 'an increased conponent from below'!

While I'm here, I may as well look into what Dave said...


Dave you said...

Reducing the collective will reduce the coning angle and, IMHO, I suspect that this will result in a small instantaneous reduction in the flap-back. The reason for this reduction has to do with the fact that the reduction in the angle of attack of a blade at 180-degrees azimuth will be different from that of a blade at 0-degrees azimuth ~ if the cyclic stick is not given a slight lateral shift.
1. Wouldn't the reduction at the changes at the 180/000 azimuths cause a left right roll and not a fore/aft pitch/
