trim
Power off in the decent, when you roll your trim all the way nose up, at what speed does it settle out at?
lets say you have 2 aboard, with a half bag of fuel.

George I am surprised you didn't know that
Re: trim
Just wondering...why would you need to roll your trim "all the way up"? Not being smart, but what is the issue? FYI, I've never needed maximum trim, in either direction, including max loads on my 48T. C.

Re: trim
well just tried the scenarios given and it's still 65kts. But I have a different engine up front and a the aircraft weights a a bit more . It was a stabile descent at just under 500 ft a min .
