North American XB-70 Valkyrie


XB-70 model in 1/72 scale
AMT/ERTL kit
North American made a fast MACH 3 strategic bomber prototype back in the sixties, called the Valkyrie. It never was taken into production, and prototypes were known as the XB-70.

ERTL AMT issued a very good kit (no. 8907) in the eighties in 1/72 scale. Also, it was issued as a "pre-issue" special, but the kit was the same.
It is huge! Over 30 inch long!

The assembly of the main parts can be changed to improve alignment of the big parts. 
- Glue the wingtip first to the main wing parts.
- Add large amounts of weight in the nose!
- The upper fuselage parts in stage 10: glue and fill / sand straight but do not glue the parts 3 and 4 together yet as to make alignment later simpler to the rest of the wing/fuselage tail.

The tail pipes! 6 of them!

You can make some small improvements:
- remove a small part of the canards (parts 28); remove a triangle shaped piece of the canard at the trailing edge near the fuselage junction.
- re-scribe the main undercarriage doors outline in the lower fuselage (part 13).
- add smaller pitot tubes, etc.

- The wheels are coloured metal (not black) as they had a coat of metal on it to cool faster. 
- The main undercarriage misses a small wheel between the two larger ones as anti-skid control. (there is some strange shape, but replace with a real wheel).

Finish the model in white. Apply several coats and polish with rubbing compound. Finally mask and add the required black panels and metal areas near the exhausts.
A spray gun is really needed here!

Decals are provided for a USAF prototype and the research aircraft of NASA. 

The end result is a large, eye catching model!
