One day I'll sleep through the night and not wake up at 3am thinking about things like this....YF-12 interceptor version of the A-12/SR-71 family. Rarely modeled and I've never seen one as R/C let alone a rocket glider. This was an interceptor version with missile bay that wound up being used for testing the aim 47 missile and doing high speed/altitude testing for NASA. I believe the only survivor is in the USAF museum in Dayton. The chines were shorter on this design because of the large rounded nose cone that held the radar system. The R/C Rocket glider uses 9mm depron, bt80 tubing and is designed for 32mm glider G-12 reloads. Currently 18.2 oz with electronics, add, paint, nose weight and motor it'll be about 27 oz ready to fly. 32" wingspan, 59" long. About 1/20 scale. Construction is identical to my smaller 24mm kit version just upscaled by 1.5x which gives me 2.25x wing area and approx same wing loading and flight times Due to size and shipping cost, no plans for plans or kitting, sorry.
