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 repetition!
Zitat von SDKFZ;6034424Hear that, hear that !
Looking good sofar, will you do the "ribbs" on those strange intakes as individuals of from a ribbed sheet ?
/ SDKFZ
I assume this is what you mean
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 bound a sleeve of half rond dowels when I was building Lucie and haven't had a use for them until now
Never throw anything away is my credo
Zitat von TomG;6036349Nice. Btw molding and casting is your friend.
I've tried moulding and casting and it's a labor intensive process for just one model. If I ever do an original model I'll consider it.

Taking the TDA's observation to heart I decided to incline the nose gear angle for a more streamline profile and less extreme angle for the nose cargo ramp. Now that I have established that area I can start on the retractable main gear.

Thank you 4 the pix of the engine!

You're very welcome, I have a lot more engine build up that I will post later but I mistakenly posted a current update on this thread. Sorry for the out of sequence Verwechslung. 
Well, back on track The drums (sic) are formed and slightly detailed there is still the intake vanes and the half round stringers on the sides but the overall effect is good.

dummied up with cowls and exhausts
I have to say the FW engine plumbing looks more authentic. The 3D model has symmetrical plumbing fore and aft and top and bottom; it looks like he took a shortcut and just mirrored the detail. Not a big deal but not how a real engine looks plus there is no fuel control, accessory gearbox, generators or CSD's (Constant speed drives for the generators) and there is no bleed air for the pressurization and air conditioning.
Close as I am to the plumbing I'm going to have to find the FW engines and particularly the bottom view.
I have an excellent top view see the 4th image below.
I've decided to forget about the PVC and make the compressor section out of 0.40 mm sheet styrene I'll do this one to completion and see how it goes. So far every thing is lining up nicely.
The #3 engine basic framework is complete and as usual it has set a standard that I will be hard pressed to equal. Everything came together so perfect than I could believe with less than a quarter mm error between the top and bottom halves and that will be covered by the fairing inboard of the engine so it won't be seen anyway
Now all that needs be do is to attempt to reasonably duplicate this on the other side.
Okay, the basic three engines are done now that all needs be done is the final sanding of the mating surfaces where they intersect the wing root and fair them into the wing. An added bonus is that the engines increase the overall wingspan by about 2.5 cm which alleviates my concern that the wings look too short.
Note that the center engine is longer than the wing engines; this is also true on the 3D drawings to make the exhaust housing come out. Can't be helped and I don't think it will detract from the overall look as the bottom of the hull is rarely seen anyway. I'm not sure how it looks on the FW model but the extra length of this model that gives it that more airworthy appearance necessitates strefching the engine. Makes it hell for engine changes though as two variations of engines must be stocked instead of one.
Seriously Blackadder, You're concerned with logistics now; Get a life!

thats epic! great job, i want to see images of the finished model1
This is one of the sections that I attribute my shelving the project for a year. I was satisfied with neither FW landing gear nor the 3D rendering.
The FW model didn't appear to be functional in that the gear would never fit into the well given the actuating cylinder and trunnion placement; the whole design just wasn't workable. Likewise the 3D model showed a ridiculously minuscule gear. Too small!
I managed to achieve a good compromise (IMHO) increasing the size of the landing pad by twice the area and changing where the gear is actually stowed. Unfortunately at the expense of internal storage area but hey it's a military vehicle so a gear cylinder in the living area isn't offensive to yer average crewman.

Revamp of the retract mechanism
I've tried all ways to get these to operate and there's only so much crap you can cram into a specific space. I've eliminated the trunnion axis and the shock strut and still no go. I guess that's why the aeronautical engineers get the big bucks. although the L1011 and DC-10 were total fiascoes for the airline industry............
pictures to follow...............
I took a few days off to lick my wounds. 
Now I believe I have come up with a solution...
BTW I consider having an actual plan of what I am attempting to do cheating. XD

Just AWESOME and Thanks, there is nothing more I can say.
It appears I don't have a Thunderhawk thread on this forum.
Well here is my current post on this subject and if anyone is interested I can play catch you up on this work.
Thunderhawk Exhaust Cones
Normally I don't use bottle caps and such on my models because thats what they look like but I couldn't pass these up at least for a tryout.

The ribbing is perfect using every third segment for a stringer and dividing the cone into thirds along it's length worked out perfectly

Now where did the Blackadder find such perfect items you may ask? Well it's Shoprite brand Fruny Green Mouthwash bottle caps from the half gallon economy size and as an added bonus I now have a lifetime supply of the stuff.

Hm. Try this: Blackadder's WIP Thunderhawk
However - it looks very cool, an its fascinating, how accurate you work!

I'm sorry I performed a search and triple checked the thread page and even checked my profile but couldn't find it. Can you make the appropriate changes to add this to that thread and delete this one?
Thanks, I can only attribute that to my Germanic ancestry. One of my goals in life is to own a 500SL sports car Black over Graphite
quite probably the best looking sportster M. Benz has produced in the past 50 years.
I'm ashamed to admit I'd also take a De Lorean.
