Thanks for the suggestions regarding the trim set, and I'll have to give the trim hold a try tonight (after work). I do think the trim had something to do with it.
There is a way to set an auto turn, to go AFK while the bird is circling up in a climb, and I've done it dozens of times in the past (flew primarily bombers for 4 years) and I too usually fly from the gunner position, usually in auto pilot.
I'll let you know if I figure it out, as it is a nifty tool to use when lifting from a closer base to target without having to draw more attention.
