I can get great 6 views in anything that has some kind of view backwards, the hellcat, one of my favorite planes, I cant see back at all in yet cause of the armour. But I havent tried tweaking anything.
The TR5 vs the TR3, is night and day though for looking back, it doesnt bother the 5 ever to look 180 back. Really the 5 feels like it comfortably has twice the viewing angle of the 3, and all of it way more smooth.
