Blackadder's Scratchbuilt Thunderhawk

I'm afraid you gentlemen and mayhaps ladies perhaps have hitched your wagon to a falling star. I wasted a week on a futile bit of building that did not pan out. Going back to square one I have in a flurry of desperation managed to come up with a better way of doing the wings. This morning I started gluing the first wing together and the foreground piece is the second wing which I hope will be more facile to build now that I think I know what I am doing.

Lost time is not a consideration as I learn greatly from my mistakes and passing that information on to my loyal readers is the raison d'être of this thread.

After much rebuilding and modification I seem to be on the right track regarding the wings. It is not too apparent in the photos but the leading edge of the wing tapers forward giving a nod to the necessity for an airfoil on a lifting surface. Of course the 'wing' (for lack of a better term) has all the aerodynamics of a truncated brick but that's the way the rendering looks.

Now I can proceed on the other wing.
 
The wings as I build them are difficult to assemble building as I did virtually inside out. There is a lot of guestimation as to where to put the internal substrate i.e. the internal panels, then there is the problem of gluing and clamping in place in the confined area (8MM) between the wing upper and lower panels. There has to be an easier way to accomplish this but I can't perceive it.
 
Have you thought about struts going through the body, extending out of it, which you later insert wings on - with the struts entering prepared sockets in the wings?
 
I've been trying to find all my posting forums as I lost the addresses when I got my new computer.

To bring this up to date here is the T'hawk as of today:

I couldn't sleep last night; I was wide awake at 1:50AM so I figured why not do a little work on the T'hawk until i get sleepy. Well here it is 9 hours later and I'm still working on the d--ned thing. H-ll I couldn't be paid for working this hard but the results are gratifying none the less. I just fastened on the wings (temporarily with a couple of screws so the wings have a bit of negative dihedral (Dihedral! We don't need no stinking dihedral! (especially negative)). I'm lucky today is Saturday or I'd be in a world of hurt sleepwise.

The faithful Zathros, rarely do I get noticed by a moderator and I appreciate it. Thks

As familiar as I am with current jet engines I'm stymied by the drum-like affairs surrounding the compressor housing and exhaust turbines on these engines. There are two above and two below and they seem to be vented with louvers fore and aft. My guess is they augment the intake air in the rarefied partial vacuum of orbital space but why they are needed on the rear as well is a mystery. After burner maybe?

Anywho here are the bits components of the basic engine rough cut and ready for final shaping and assembly.

Taking the rough cut crescent pieces, I tacked them together with a couple of dots of ambroid and sanded them to the final shape. Then separating them more or less in the middle I reversed the two pieces to see how well they conform to their mirror inages. Then I compared the ends to the middle. Happily they matched up pretty good.

The whatever it is cowling for the engine basic construction. The first two I made just for practice and are 23 mm long and the base flairs slightly. They will be abbreviated and used on the belly engine. The next set will be for the wing engines now that I have the specs down and will be 22 mm in length.

Only eight more to do, I do so hate the repetition!
 
Have a look at the prototype. This will be used on the middle engine below the hull and was practice to get the spacing down right.

I bought a sleeve of half round dowels when I was building Lucie and haven't had a use for them until now.

Never throw anything away is my credo,

On my computer and using Opera for a browser I need only righ clikck and open the image to get a full sized image; that or clicking on the "undefined" icon above the image.
 
You mean the one that reads:

"This image has been resized. Click this bar to view the full image. The original image is sized 1792x1200.?

Click to expand...

The icon is an '!' in a yellow equilateral triangle and when you click it the image expands to full size and the yellow bar has the script 'undefined'. when you click it again the image returns to a rather large thumbnail and the bar still retained the 'undefined' script.

No big deal, probably a glitch
 
The glitch is probably with Opera as in Firefox and with I.E, Bing, and other web browsers the yellow bar reads what I posted previously. Since it works, it just words you don't need to bother reading. It's all good. So is your model!! :)
