10-4: understood... no worries
On to much more enjoyable topics.

I know safety should always be a concern for everyone when dealing with rocket propellants (and this isn't meant to downplay that very important fact), but honestly, is a MMX cato really that catostrophic? I imagine the model may take a beating, but I can't imagine it being a huge "safety" issue if someone is following standard launch procedures. Of course, there is the inherent danger of playing with fire, so there is that I suppose.
Thought we were moving on to more pleasent subjects? Well if someone wants to still the pot.
In one of the two MMX-II motor catos I've personally been near,
I was surprised by the violent destruction of a Quest Space Freighter LBP by a single MMX-II Toothpick related cato. There was litterly NOTHING to be found of the model. All that was found of the motor casing was an outside single wrap fragment. Our Range has 50 foot leads and one of the kids (Spectator not flying) watching the launch from outside the perimeter was hit by a piece of flying plastic or maybe nozzle. Did it injure or hurt....I'd have to say maybe just slightly as the kid was in shorts but the potential for eye or other injury was certainly there. Further it was enough to cause the parent to pack up the kids and leave. NOT a good thing for the hobby.
Had someone been using a standard 15-20 foot lead electron beam or Quest pistol grip controller during this event there might have been a much more serious result. Standard construction paper and wood models may not have been as serious but in this particular case, This MMX Cato had the potential to become catostrophic.
Lets not underestimate by prejudges.
Today I saw MicroMaxx in action for the very first time. We tested a paper tube prototype that landed in the back of Bill's jeep, the second was a pre-made one. I lost sight of it, but I could hear the streamer rustling as it came down. It landed about 10 feet from the jeep. You could almost call them "truck bed" fliers as well as backyard fliers.
BTW, John? A question for you....
Why are you flying Christmas tree ornaments????
Years ago (before Quest offered them as such), I bought a Saturn V and Shuttle, and convinced my wife (begrudgingly) to let me put them on the tree that year. Since then, she and the kids have insisted they be put on -- they like 'em!
So, around Christmas, you are hereby banned from my house, lest you raid my tree for rockets! :gavel:

No, you are wrong! A "ghost" of cheese-cutting Cecidomyiidae wouldn't produce a larger, but rather would produce a MUCH larger total impulse!... Not denying these micro motors are fun and have thier niche, but I think a small cluster of gnat farts might actually have more power.

Seriously, Micromeister and I do agree on this issue (and the overwhelming majority of other rocketry-related topics, too). Knowing how much power is actually packed into these pip-squeak propellant modules, I would not want to be nearby when one of them burst due to over-pressurization!
Micromaxx motors are the Henry Pyms of the sport rocketry world!

Part of the reason that they were so heavy was that some designs, like the Space Fighter and the Space Shuttle, needed a considerable amount of nose weight to get the CG far enough forward for a (somewhat) stable flight. And the Saturn V was just really large for a molded plastic MMX model. The UFO was fairly lightweight, but it was so draggy that the flight was sort of "conceptual." Saucers that size can boost better than the plastic RTF UFO if they are made out of cardstock. A cardstock UFO that has been sprayed with a couple of light coats of clear coat will be more durable than one made from thin vac-formed plastic. I still have every one of the Art Applewhite-designed Micro Qubits. Micro Delta Saucers and Micro Original Saucers that I built when I resumed rocketry in 2004, and they are all in great shape.After reading all of these posts on how heavy the LPB's are has anyone ever nodded one so it could be vacume molded using a lighter plastic?

Very interesting!How about the new Rocket Racerz, they use MMX motors, and they move pretty well! Page 26-27 of the new Quest catalog.
