X-15A-2 Ablative Heat Shielded - the Mach 6.7 X-15

Heres what I know...
X-15A-2 is aircraft 66671 and is currently parked at the USAF Museum in Dayton Ohio, in its original black finish.
Ken West's X-15 model is the same aircraft featuring the lengthened fuselage.
The X-15 rocket plane set numerous speed and altitude records back in the 1960s.
To achieve higher and faster flight, the aircraft was stripped and coated with a special ablative heat shielding material.
The pink coated rocket plane was then painted white (basically because the Test Pilots didn't want to fly in a pink airplane!)
This "white" version is the focus of this thread.
A-2/66671 made multiple flights to the edge of space and achieved a record speed of Mach 6.7(4520mph) and highest altitude of 67 miles (sub-orbital).



Just getting started on this repaint/remod of Ken West's 1/33 scale X-15A-2 model.

Struggling to understand some of the assembly...since I have never personally built the original model.
And understanding the assembly of parts is an important factor when trying to recolour the parts!

So, I may have to build as I go, to test everything and keep up with understanding the assembly.

I'm going to repaint the big fuel tanks too, since they were part of the record setting flights.
I haven't decided whether I will bother with the dummy ramjet nose cone that was mounted under the tail fin.
It didn't really have anything to do with the record setting flights, other than the fact it was there on one or two flights.
However, I will shorten the lower fin as it was.


Not sure how fast this project is going to go...I was planning on not doing any big projects this year.
Just wanted to focus on Koolwheelz models and not much else.
But I need a break from those...so maybe this is it.

Glad to finally see this important vehicle done. That said, I'd still love to see the original -- and shorter -- XLR-11-powered X-15, 66670, with options for its rollout scheme and later markings options for the vertical stabilizer. (X-15 tail markings often differed from mission to mission.)

Looking forward to see the repaint completed.

If you want to drop me a line, I can send along some detailed diagrams of the markings....

So, to anyone who has assembled this model...
looking at the kit, it appears the intended assembly is to build each fuselage section
with a bulkhead style former at either end of the skin...and then "butt join each section.

First section, for example, has Nose sections #1, #3 and #4,
and there are six bulkhead formers for these three sections.

I am curious if anyone created tabs or joiner strips for the fuselage skin connections
and used only one former at each joint?
Or is the butt joint approach ideal?

I built It twice -- the X-15A-2, and then modified a version into the pre-stretched 77761. Both times, I used the bulkhead formers and butt-joined the sections. Worked great both times. The bulk of the fuselage is just a long tube, and the chines hide a lot....

So, I've manged to recolour the first few parts of the kit and I test printed to check my work.
I went ahead and assembled some parts yesterday to see how things look.
Just a preliminary test.

I decided to stick with the clean white pre-flight look rather than the worn and stripped look of the post flight X15.

I'm playing with colours and artwork...I've reduced outline thicknesses and colour to a mid gray.
I'm experimenting with the various surface marks and discolourations.

The white finish is going to be much less forgiving than the all black look.
Part outlines show up a lot worse, seams and connections are more obvious.
Any errors or mis-fits are going to stand out a mile!

I have limited experience with the double former/butt join method for fuselage sections...and it shows.
I tried it years ago on a Marek aircraft kit and didn't like it.
I've always built with joiner strips and tabs, so this will take some getting used to.



Ken's instruction say to use 110lb cardstock.
I thought that was kind of thick...and i don't have any right now...so I used 65lb.
Ken suggested .2mm card for the bulkhead formers.
Even my cardstock is thicker than that!?...so I was perplexed by that.
I used some easy to cut .8mm cardboard.

I tried to cut everything very accurately, but my bulkhead formers were too loose fitting...
except for the one ahead of the nose gear recess...it ended up being so tight that it caused a ridge in the outer skin.



I'm going to have to find some 110lb cardstock and try thinner card for those formers.
I might also add some reinforcing strips.
I wonder if I should try making tabbed joiner strips for the fuselage sections?

I made the nose ball out of a wooden dowel.
Just found the right diameter dowel to fit the hole at the end of the nose cone...
then sanded it round at the end, then cut it to about 1cm length
and glued it into the nose cone.
Oh, and I painted it silver, then dry brushed black, then clearcoated it first.



So things are looking okay so far...my build issues notwithstanding.
Once I get some more cardstock, I'll try another test build.
Don't want to go too far until I've settled on the artwork basics.

Looks good. Thanks for taking this on.

And, yeah, plain white cardstock can be unforgiving. Cut edges just seem to discolor all on their own. Sometimes, when burnishing parts, I'll lay a piece of wax paper down on my cutting mat so the part won't pick up any dirt. I see why some styrene modelers wear surgical gloves.
