The MTL used to do the same (no landing gear) but this is a few months back.
In defence of the fleet P180, I have to say that my reference P180 (the FSD model) also begins to roll when cornering above 15-20kts, so I suspect that the fleet model is quite accurate in that respect.
Been a long while since I used the fleet P180 (and a couple of FS installs). If I get a chance before the weekend, I'll install it meself and have a look.
