This Blackbird model has some very small and fragile parts for the landing gear that needs to be assembled/put in place. A small amount of glue might be needed to secure the pieces. One could easily chose to not assembled the landing gear and model the plane in the inflight position, but be advised that the wheel well covers are molded in the opened position.
This is really a "no-play" model or a "display-only" model. It is mostly metal and very heavy. It also has a number of antennas which look great but are very fragile. If you have small kids that like to play with your models, save yourself some frustration (and money) and wait till later to get a model like this one. The box is labeled as not suitable for children under 14.
The maker of this model did a good job with this model, specifically the color scheme and the markings are very crisp and clear. The panel lines and hatches are very nicely done (engraved).
The packaging of these models is very nice, it comes in a rectangular styrofoam pack. The pack in turn, goes inside a full color cardboard sleeve.
The pack measures 8 inches by 8 inches by 2 inches.
The Lockheed YF-12 was an American prototype interceptor aircraft evaluated by the United States Air Force. The YF-12 was a twin-seat version of the secret single-seat Lockheed A-12 reconnaissance aircraft, which led to the U.S. Air Force's Lockheed SR-71 Blackbird twin-seat reconnaissance variant. The YF-12 set and held speed and altitude world records of over 2,000 mph and over 80,000 ft (later surpassed by the SR-71), and is the world's largest manned interceptor to date.
