Nosegear bay
How do I cut a nosegear bay in the fuselage. I am not sure that the tutorial by Mike Crosthwaite for 3-D landing gear bays in the wings will work.

The tutorial that you refer to will work. The principles are the same I have used it with success on some of my planes, that I do in FSFS2.11. You might have to be a little flexible, but with a little experimentation, it will work.
