I built a 1:48 of YF-12A (I believe the A is supposed to be there, too) a few years back. Rather impressive looking, the whole thing is over 50cm in length. The YF-12A was the "fighter" version of SR-71, built probably mainly as an experiment and to support the new policy of no spyplane overflights (what, that's not a spyplane, that's a fighter). The main differences were that the front chines were squared off for the front-looking radar, the addition of the missile bays (how do they open those doors at 3.5+ ?) and a large stabilizer fin below the stern (folded up during takeoff/landing). The recon officer's position was equipped as a weapons officer's position. This information from a reasonably level-headed seeming book called "SR-71 Blackbird" by Signal/Squadron publications. Can't vouch for them, obviously. -- /* * * Otto J.
