Hold Back Fitting
Thanks Steve, and now for..
The "Hold Back Fitting".... not a lot to it, but it is a crucial component. It's purpose is just what the name describes, to hold the model onto the pad until both motors light. The tricky part was providing clearance for the lower motor when it kicks out the parachute while it's still sitting on the launch rail. Also, the upper support has to hold the Orbiter onto the Booster once the "Mouse Trap" has sprung (if it, the Orbiter, slides down more than about 3/8th of an inch it will fall onto the ground and probably hurt itself, a bad thing). The burn strings are not shown in these photos. They are so thin you couldn't see them anyway. 10Lb test Spider Wire (looped and pull tested to 20lbs)... they don't photogragh very well. First chance I get I will update these pix with a photoshopped overlay of how they get routed. Probably would help to show where they attach to the underside of the model too. Regards, DJ

Launch Day 1
It flies!
...had a rare day of clear sky's and calm winds. Despite a few teething problems with motors and the hold back fitting, I did manage to get in one flight. Boost was hands off, straight up, arrow straight to about 300 feet. The Orbiter flies beautifully. Had some friends take a few shots of the actual launch but it may be a few days before I get them (I was a little busy learning how to fly it). Posted photos show before and after. Regards, DJ P.S. My apologies for the poor quality of the pics... didn't notice until I got home I had some of the settings on my camera a bit off.

Thanks again Steve! Oh, BTW, a friend did get some video ... , you're also stuck with a few more before and after shots (by a much better photographer). Next entry will outline what I learned from the test flight and what needs to be modified or improved before the next flight. Also coming, detailed specs with final weights and dimensions (didn't want to post them before because, frankly, I didn't know what they would come out to be).

Excellent! Looks like all you need is a bit more up elevator. But that's all. Fantastic flight. Congrats!

A beautiful flight of a well-planned and well-executed model project!
I can't help thinking that a winged version of the Ares I's new 5-segment Solid Rocket Motor, combined with a proportionally-scaled winged orbiter, could be a scaled-up version of the BlackStar TSTO reusable launch vehicle.
