Too put it bluntly it takes expereinced modders like the team considerable amounts of time to model, texture, (animate) and code a simple vehicle. without any experience you are trying to make a vehicle more complicated than any vehicle inexistance in vanilla 2142. You probably really need to think about learning the basics of any of the disciplines mentioned above before you try a project of this magnitude. I suggested downloading the official EA/DIce tuts then heading over to bfeditor.org for furthure information. No-one is going to do this project for you, you will need to learn for yourself.
