Something to watch out for is that, unlike most lower-performance planes, it likes to assume a slightly nose-up attitude in cruise. As I understand it, that's due to a combination of the high speed and the angle at which the wing joins the fuselage. I thought I was doing something wrong at first until I started to read other commentary about it, though from the beginning it flew very nicely when trimmed for high-speed cruise... just with its nose in the air.
