Here's a couple of pics of my 137% Stiletto booster. The sustainer is normal construction. Just a normal engine mount and no stuffer. I've gap-staged stuff with longer gaps than this without a problem.

NOW I see what you're saying...

Thanks so much! And thanks for the propaganda about gap-staging! The pictures help a lot. My wife will be talking to me, explaining something, and I tell her, "Let me *see* it!" --The first time I did that, she said, "You don't *believe* me!" I said, "No, I just need the visual input to understand what you were saying." (Can you tell I take pictures for a living? ) Thanks again, Buzz! Cheers,

Propaganda? Now I feel as though you don't believe me. I have seen one gap stage model fail to stage. It was Pete Always Aerobee at a MIVARS contest. The gap was probably around 6" I'm guessing, but that happened in the early '90s and my memorie's fading. I do think I have the flight on video though. I haven't had any gap stage failures and I've staged with gaps up to 8". Come to think of it. I did have a Quest Zenith fail to stage. There is a small gap, but I had punched "pass-port" holes in the coupler as a precaution. I blamed the failure on the narrow throat of the upper stage B6. I hate using B6's for upper stage motors and would much rather use a B4, but no one makes a B4 sustainer motor anymore. I add a little Centuri sure shot to B6 sustainers now. C6's seem to stage fine with a gap. The major problem with long gap stages is the booster recovery. My slip-pod booster works well, but I haven't built anything past the research prototypes. I do have a BT-3N Terrier on the build queue that will either use a Perfect flight timer or a slip pod. Haven't made up my mind yet.

About that "propaganda"...

I mean, I can get information *anywhere.* Propaganda is in *much* shorter supply. Cheers, as always,

I was digging around on YORF tonight looking for this post, since I was trying to recall about the gap-staging for this model. I was looking at the same size upscale for the Centuri Lance Corporal, http://forums.rocketshoppe.com/showthread.php?t=9657 ...and I ran into the same question I had regarding your Stiletto upscale. Sure, that was a week or two ago... (cough, cough) Cheers and blessings,
