Pilot, as you can see, making a plane for FS is not easy. In fact, anything involving 3D modeling is never easy. That's what the tutorials are there for. At first glance, the tutorials may not make much sence, but over time, as you read them real carefully over time, they will make sence.
It takes understanding of both addon development in Gmax and the open architecture of the Flight Simulator world. It took many months, if not years, for many of our developers to both learn and understand Gmax and FSDS. So, our best advice and recommendation is to go back to those tutorials [that were made by professionals who have clear understanding] and learn from them.
I was just like you when I first got Gmax since FS2k2. Going around the forums, asking people around for this or that. But in the end, I came to realize that there will be a time where I have to learn to do things on my own. Besides, not everybody here in the forums will be around forever.
Hmm... is it just me, or am I starting to sound like my parents?
