Well done! and the folks at Dragon also released a model in 1/200 concurrently of the U.K's flying wing (despite the small tail ) better known as the Avro Vulcan. Both kits are even sold prepainted.

Flying Wing thread, Flying Wing thread !!!! bouncing off the furniture, clapping my paws with glee.
Am glad you included Ninfingers' flying wing whiff thread, its required reading for any flying wing nut. I built, in paper, every one of those designs in that thread 10 years ago, even adding three more, such as a X-15 carrier in NASA colors and a RAAF AWCS version plus a civil airliner convert.
In looking at a picture of the parts trees, these new kits avoid the one problem that was in EVERY previous kit of the flying wing-every scale up until now (even the vacuforms) . In order to save on precious $#@!%$ box space, all of those other kits had the aircraft in three segments, a center section with engines and two outer wing panels. The fit and straightness issues made each model harder than it needed to be for assembly, adding metal rods to brace the internals and buttloads of PSR ugliness in the end.
The 1/200's have a upper half, and ...drum roll....A lower half! Just like logic was in charge! yay!
If you'll pardon my euphamism, these new kits can breathe fire on all the rest AFAIAC.
