haha I'm not saying the PinUp Girl will die! lol

What I meant was, because I have altered the cockpit cutout and the canopy,
so I am not going to worry about finishing this model perfectly.
I'm not going to try to make a clear canopy for it.
..and I'm not going to worry about displaying this one.

But I will continue to build it and use it as a test bed for rest of the parts.
And use it for more photos of the design and assembly.
But I will have to  build another "display" model for myself.

in fact, I fitted the final test canopy (paper version) to the pinup Girl...
but I cut it open and glued it in place (since it doesn't fit this plane properly).

I also fitted the Ridder and the Tail spar.
And I built the main Wing Spar assembly.



Tonight...while watching NASCAR, I will test build the Main Gear Wheel Wells
and if all goes well, I might assemble the Main Wings!

Ah, Nascar ... I find I am very productive doing other things while it is on

<--- Obviously not a Nascar fan
There are no strangers in this world ...
Only people I haven't embarrassed ... yet

I'll just ignore that last comment...probably just another pointless Hockey fan.
hahahahahaahh Hockey...a waste of ice.

....

In other news....
Wheel wells went together fairly straightforward.
Everything is small, so a little patience goes a long way.
I added a bunch of glue tabs to help with construction.

It all seems to fit into the Spar assembly okay,
I just hope it all lines up with the openings in the Wing skins?

Haven't decided yet if I need to add some glue tabs to attach to the wing skins?

Glad that Pinup Girl will be created, even if in not "for display" condition.

Haven't decided yet if I need to add some glue tabs to attach to the wing skins?

Why not add the tabs? Those who think that they can get away without them can always cut them off. Options are good ;)
Cheers,
Tomek

Yeah I agree
just have to sort out all the clearances around the spars etc.

Okay, much work continuith....


Big thanks to Ted over at ArmyAirForces Forum who has supplied me with "Special Project Numbers"
for a many of the P-51s I plan to offer (as repaint versions)

I know this is a very small detail on the aircraft, and unless you have a printer that can print
high dpi, it may not even be that visible on the printed model...but that doesn't mean I don't
want to try to be as realistic as possible with the paintscheme and markings.



...

The Wing Spar assembly went together as expected, however the parts are lightweight, and some of
the slots and cutouts create some very thin sections. 
It is definitely a handle carefully and take your time assembly.

I also added some spreader braces that really strengthen the entire assembly and help keep it all square.



...

Wheel Well boxes  are an oddly shaped item, not only in overall shape, but the side walls are heavily angled
to match the profile of the Wings...so its a confusing fold and glue item.  Again, take your time and it goes together
quite nicely.  I added fold and glue tabs for the edges but these are a bit of a problem since they enlarge the overall
size of the wheel boxes and I needed to trim the Spar cutouts to get the assembly into place.



...

As a result of my adding tabs and trimming things...and as a result of my quick and dirty build style...
I am having some trouble getting everything to line up perfectly.

The Spar assembly needs to be properly cut and assembled squarely. 
The Wheel Well boxes need to be carefully assembled (maybe with thinner paper glue tabs? or maybe even edge glued)...

The Wheel well boxes have to line up perfectly with the wing cutouts...theres no room for misalignment here.
But the Wing skins also have to fit onto the Spar assembly.

This is the very first time I have ever built a recessed wheel well assembly like this and I obviously have a lot to learn.
But even with my inexperience and adjustments, the wing still went together! So I am still very positive about this!

...

Since I am also designing the Landing Gear parts, I decided to do a test build of those at the same time.
I am experimenting with some inside part for the Doors to make them more 3D and make the
outer Door fit better against the gear supports.



Inner Doors also have some cutout layering to add 3D effect.



...

Wing from above looks pretty good too...just got to add the wingtip parts.



This design, like other Mustang paper models, use small paper parts and short tubes to add the Machine Gun
ports to the leading edge of the wing.
Although these wing ports are expanded "bumps" in the front edge of the Wing, they are hardly "tubes".
The scale model effect always sticks out way to far in my opinion.

Not to mention the fact that the parts to create these Gun Ports are extremely small and difficult to assemble!

I decided to go a different way and use some surface artwork to simulate the gun port bulges.
If nothing else it caters to lesser skilled builders (as I generally try to do with a lot of my adjustments).



...
I'm not 100% happy with the way the Gear recesses line up with the Spar cutouts and then with the Wing openings.
I'm not happy with the trims I had to make to get it all to fit together.

But I think my problems were all caused by my own actions...not the design of any of the parts.

So I am going to rethink a couple of modifications...make a couple of adjustments
and give the wing another try, this time with more care and accuracy.
I might even ask for a test build (if anyone is interested)...after I get some Instruction diagrams sorted out.

Test Build updates for the first week of May!

Did a final test build of the landing Gear last week.
Also assembled the Doors for PinupGirl.
Everything looks good.



Got Chris M to try a Wing test build...after I made a couple of adjustments.
He seemed to have no trouble...just pointed out his method and a couple of necessary  tweaks.

(He didn't like the scale - compared to what he normally builds. lol)


Anyway, I also needed to test build the Wing again, so I can finish "PinupGirl"
and to test all the adjustments myself.

I decided to try a different assembly approach...first, attaching the two wing halves with a simple glue strip.
This seems to make it easy to center the WheelWell boxes properly.
Also, I am fitting the "Wing Crook" part at the end (as per Chris' instructions).
And I am fitting the WheelWells to the Wing skin first, and then fitting the whole thing to the Spar.
Seems to be going okay so far.
And I was able to line up the edges of the Wheel wells quite nicely!



So, now I am gluing the Spar assembly into place and later today I will finish by wrapping the wing skins
and gluing the trailing edges into place.

Note: I have also added the missing joiner plate (not shown), that runs up the belly of the plane and will
cover the wing centerline seam.

One more update...re the Wings

Finished up the Wing assembly, and as I said, I followed some advice and attempted to attach the Wing "Crook"
parts at the end. This is only the second partial build I have ever done of a Wing with Wheelwells, so I am still
learning...but, the skins went onto the Spar assembly nicely.

[This time I joined the two skins together at the belly center seam before putting them onto the Spars.
I also fitted the Wheelwells to the skins, which was very easy at this point.]

Once the skins were on, wrapped and glued into place, I tackled the Wing "Crook" parts.
At first they fitted real nice.



But when it came time to wrap them under and line them up with the remaining edges of the Wheelwells
I had a bit of a struggle.
I think it will help to round out the leading edges of the Wing ribs (which I am going to do) to provide a little
more room for wrapping the crook parts around the front of the wing.

Anyway, I eventually got the wing wrapped and finished...and I moved on to fitting the wing tips.



You can see here how much I struggled to get the wheelwells to line up with the wing crook parts...
I pulled and twisted so hard I eventually folded and creased one of the parts.

I have to admit, that I think most of this struggle is my inexperience with the assembly and switching
assembly methods before I had even mastered the first one! lol
Its obvious that all these parts line up...if you make sure you have everything in its proper place.
Once again...I say its always a good idea to dry fit parts until you understand the assembly and then proceed.



In the end, I am satisfied with all my adjustments so far and I am moving forward with the final assemblies.

The "Penultimate" Update...
(always wanted to use that in a post)

I say penultimate, because I think its getting down to the wire now!
This test build requires a few more small items to complete it,
but other than that I have completed the "test" part and made almost all the necessary adjustments.

As you can see "Pinup Girl" is sitting on her wheels now.

[having a little trouble with my Camera flash unit...seems to be overdoing it. All my recent pics are overexposed
and over contrasted. I'm doing my best to tone them down in post editing.  I have changed camera settings so
I think something has gone wrong with my flash itself.]




I finished the wing installation by gluing the assembly into place
then fitting the wing root fairings
and the belly scoop.
A little rushed I know...but for the purposes of establishing fit and adjustments.

You can also see the installed Landing gear including the newly designed Tail gear.



Front gear doors in place...I still have to attach the Tail gear doors.
And, as I said, a few other small parts to attach and then shes done.

Next step for me is to finish the Instruction pages and diagrams.
Then I will make Pinup Girl the first release.
Also time to start making a list of planned repaints!

Looks really good Dave! Sexy Pinup Girl!

Interesting, I see more and more designers ask other modelers to do the test build. I really respect the fact that you do it yourself, Dave. That's in my opinion the right way. Keep up the good work!
Cheers,
Tomek
