I have flown a plane with a good amount of wing-tip dihedral. It was a nightmare to outside loop. It would flip over unless I was perfectly level when starting the loop. Even then it would require some serious corrections when inverted to stop it from flipping over at the bottom part of the loop. But the again, other factors of the plane might conteract the flipping tendancy (like a large fin/rudder). The plane I flew did not.
Anybody else find this?

Dihedral doesn't make any difference except if the dihedral angle gets too high it is difficult to keep the airplane level thoughout the outside loop. Dihedral is a flying qualities thing and not the capability of doing the loop.
Mass distribution isn't really that much of a factor if you can keep the wings level.
