Hi Tony,
So far I have actually found the Skygate Hawk the easiest of my models to transport!!!! The fuse splits in two so, depsite it's size, it simply fits in the boot with the seats down!
The P160 is, I believe, 108mm dia. whilst the XL200 is 120mm dia. - check the space between the rails etc?
Rgds,
Mark
PS Must remember the 200 is not 200N!!
