very cool - the Sandhawk is one of my favorite scale rockets. Did you scratch build this, or is it a PML or Performance kit?
It was scratchbuilt, as were all my models. I also had a Dragon III that I scaled from Alway's book. It wasn't as big, only eight feet total. I had a single 38mm mount in the upper stage, and a 38 in the bottom center with 4 29mm mounts around it. I had it set up to boost on the center 38, I used an "I-295" and then airstarted 4 H-100-s just before the "I" burned out, then staged to another I-295. Looked really cool going up on a column of white smoke, then changing to black, staging and turning white again. Timing the airstart and staging was critical, or it would tip over as the thrust dropped off. I lost it when I had a failed airstart; the booster trashed itself, the chute ejected too low to save it. Since the upper stage was timed to fire at the end of the center engine burn PLUS the airstarted engines, I had a couple of seconds of no thrust before staging. The upper stage tipped over almost horizontal at a couple thousand feet, it ignited and we never saw it again. Luckily it was pointed toward an area we knew had a large swamp and no houses.

I liked scale models; most of my rockets were in the H to K range and 3 inch to 5 inch diameter. I built an ARCAS, a Black Brant, a Mercury Redstone, a Standard, and a Little Joe II. The Little Joe was neat; it was only about 4 feet high and had a ring of 6 29 mm mounts and the engines canted outward 5 degrees. I used to launch it using G-25's, I could fly it with either 3 or 6 and it made this huge column of smoke for its size because of the engines' cant outward.
