My concept (farther stages)...

[Demo]

... with "borrowed" parts from the F-5A on the adopt-a-design page. (is the author by chance a member here?)

Here she blows.







Thanks for viewing! Critique welcome!

(This is the fourth construction of this concept. I call it the "Fusion" with the fictive company 'Cleigh Avionics')

Allright!  Now THAT is an aircraft . . .

If I may recomend . . .

On the intake (around the cockpit and fuselage) make the black section a recessed part.  It looks too flat right now.  It should look something like a jet intake on a fighter jet . . .

Looking good  :)

The thing that comes to mind though.. if it's a ultra-mach prototye... it would probably be a delta-wing of sorts, without tip tanks.. And the refueling appendage would have to be retractable. You could key-frame it as a tailhook or something..

It does bring to mind the Leduc (French) ramjet experimental plane..

I really like it, but the original skid version is even better - wondering if you might be releasing it as freeware (and what the performance might be).

I was thinking maybe something a little more sensual, like such (see below)

[Travis]

I like that version better, but how about making the bottom wider than the top?  Like an inverted V or similar?

Also, give the shape more sides.  Don't worry about making it too heavy on polys right now, since you probably aren't going to top 50,000 in this iteration.

I have no idea how to make shapes like that!  ;)  Thats what got me onto the idea I have now... all I could make was Cones and truncated cones and clyinders and what not.  ;D

Take a cylinder.

Give it 5 height segments and 18 sides (the default values in Gmax) and then click the tab labled "Modify".

Set the radius to 2 and the height to 10.  This will give you a cylinder 4 ft tall and 10 ft tall.

On the modify tab, just below the "Modifier List" you will see a large window with "Cylinder" highlighted in green.  Right-click on "Cylider" and select "Convert to: Editable Mesh".

Now click on the "+" sign next to the words "Editable Mesh" and select "Vertex".  Now go to either the side or front/back view and select the entire top section of vertices.

Now go to the top of the Gmax window and find the button "Select and Uniform Scale", which is right next to the "Select and Rotate" button.  Click and hold on that button until a rollout appears.  Select the second button (looks like a grey rectangle with a small white rectangle growing out of the side).

Click and hold on the selected vertices and move the mouse around.  Just play around with that for awhile, and you'll get some really cool shapes.  One of the simplest tools to use, and it can do all sorts of stuff.
