So, will the CR-56's just be cut out of standard 0.05" fiber, or will they warrant making new paper centering rings? With ~1/32" gap all the way around between the ST-5 O.D. and the ST-6 I.D., just the fiber ones ought to work fine.

Also, will the Nike-boosted sounding rockets and the 2-stage Aero/Astrobees be built stock for 2 stage capability, or include provisions/plans for modifying the stock, basic designs, or just design them for single stage? As long as you could get a booster motor and deployment motor clustered in the booster (which would be a slight problem for the BT-58 Aerobees and Astrobees, they're about 0.02" too small I.D. to fit a cluster of 2 ST-7's, though, 2 BT-20's would just barely fit (0.026" of wiggle room)), it shouldn't be hard to design them for one or the other, and get a positive booster recovery system worked out with the ejection-capable tubes.

And finally, when coming up for design ideas for these, can/should we take into account future motors? For instance, 15mm motors seem to open up new clustering opportunities for the larger models, but if the kits are scheduled well in advance of any new motor developments, we should just concentrate on what's currently available.

These look like fun.
