I started work on this a few hours ago just for rendering fun, but I may use the early form which I was using into a civ unit later.

I'm using http://www.colacola.se/wip_p47.htm as atutorial for those who want to tag along, I'm using blender though and very different methods.

1st step:

Set up reference things, the shape between them is actually just a cylinder set up to match the maps.
2nd step:

Added Wings and tailwings, smoothed everything out. Increased polies a great deal.
The render so far looks like:

That's where I am so far! No texture yet, this is just modeling.

EDIT 1:
3rd Step:

Added cockpit and propeller.
4th Step:

Created a new texture, nicknamed it "Jersey Special". Still need to work out shading and positioning.

A LOT of editing done on both the texture and the model.

Got rid of the planning boards, created new textures, materials, etc.

I'll post a new render later.

EDIT:
First Render completed, we still have a ton of work we can do though!
