Sounds good. Okay here's a tutorial:
The SOASE plugin has instructions for the initial import but here's what to do afterward to prep the mesh itself to be worked on for FS2. This includes resetting X-Form, resetting pivots, proper positioning, flipping normals, welding vertices, and restoring the smoothing.

This is what it looks like upon import. It is riddled with problems we shall resolve right now.

Rotate the model so it FACES the +Y Axis and the sides are to the X Axis. Also mirror the model along the X-Axis!!! Some of the models are asymmetrical and the plugin imports them wrongly mirrored. Do this to fix it.

Next up we reset the pivots and transform. Click on Affect Pivot Only then press Reset: Transform. This will set the pivot's rotation to 0,0,0. Just where we want them and devoid of problems. Also feel free to set the transform coordinates to 0,0,0 on the coordinate boxes on the bottom of the screen. FS2 demands ships be perfectly centered on the origin. Least their pivots that is.

Next up we reset the X-Form. This is pretty much standard procedure here.

The model goes black, the normals have been flipped! No prob, go into the modify tab and scroll down to 'normals'. Once selected the model's normals are flipped and all fixed.

Next up we're gonna weld verticies. Right click anywhere in space or on the model and scroll down to Convert to: Editable Poly.

Go inter vertex mode by right clicking and going into the appropriate menus.

Now scroll down on the right bar till you see 'weld' and press the square button next to the button. In the threshold type 0.01. This ensures that only verts on top of each other will get welded. You will notice the smoothing is screwed up. This is the last step.

Scroll the modify rolldown and select smooth. Press automatically smooth and type 35 in the threshold. It will be a good starting point but you'll have to apply smoothing to certain parts of the model to make them resemble the original. This is a sad but 100% necessary step. Very important. For those unfamiliar with anything about 3DS.... this is gonna be a pretty confusing work. You need to go into either element or polygon mode and select faces that need smoothing then going into the modify rolldown and do smooth on them, there you can specify the smooth threshold only on the selected polygons. 35 is good for smooth, unextreme surfaces. 60-65-75 is good for octagons or hexagons. 45 is good for some things inbetween.
That's it for prepping a model. Serious, as it is right now the model is ready for anything we want it to. I'll post up the texture tutorial sometime later. Maybe tomorrow, I have to do something called 'eat' right now.
