Yes I use Flight Sim, for some aircraft, I can then work out how the landing gear works. 
Making models for Flight Sim is a different process, able to use large textures and more polys then Trainz to do a much better model. I have not taken up that pursuit yet. I like to push the boundaries in Trainz, though there are limitations.
