Helmet Fire
I have not experienced the pitch up that you mention. Mind you, most of my time up at the altitudes that you mention is enroute IFR. The autopilot has caused a couple of hiccups but nothing to write home about. Fire bombing for a number of seasons but at relatively lower altitudes than you mention.
Certainly the inflow roll problems associated with a low level trun to the right. I have the bruises on my left knee to prove it. You can get the same inflow roll problem (running out of left cyclic) with a steep approach with a wind from the left.
That being said - I love the BK.
