Coaster Questions
Does anybody know why the old Coaster motors had an outer paper wrap, in which you cut off the packaged end on the nozzle end?
I was looking at old pictures and finally noticed there was a broken line around the nozzle end designating that you were supposed to remove it from that point. What type of paper was it? it looks like a smooth wrapping type paper. Was a simple cardboard tube underneath? Was it to prevent moisture from creeping up those massive nozzles?

The wrappers aren't smooth like the Mini-Max - they have a rougher texture, more like a Kraft paper grocery bag, or a manila envelope. The dotted lines are at both ends, like the Mini-Max. The motor tube itself is, again, very similar in thickness and texture to the Mini-Max motor. I'll try to get close-up photos tomorrow and post them, along w/photos of the old Estes B3's from the other post.

Pics below show the dotted lines around both ends of the Mini-Max and Coaster motors, along with the aptly described 'massive nozzles':

Going slightly off the Coaster thread, but staying on the Black Powder Nozzle thread, the Rocketflite H220 is by far my all time favorite black powder motor. And the F50 is right behind. Coaster motor shown for comparison.

What was the "G" version of those Rocketflite motors ?
I had one maybe 16 years ago that I flew in a Semroc 1/2 scale SLS Arcas. My backyard was really nice to fly out of. It bordered a 500+acre Soybean farm that I had permission to recover rockets in. I could easily fly under FAA limit H-power out of. I just had to watch for Aircraft traffic as it was within FNT approach control. Commercial and Cargo aircraft flew directly over my back yard.

Re Rocketflite 'G' motors: I believe the H220 was re-labeled as a G at some point, but they also produced another G - Steve Naquin or StefanJ can probably help out here.

Wish we could get proper BP high-thrust port-burners like those again.
Nothing but mamby-pamby excuses why we don't. We need IRON-CLAD hold-harmless agreements between companies and manufacturing employees, not lack of making them. Just like the NFL needs to do with their players, not some weenie weakening the game. Both are risky professions. Don't want the risk, DON'T SIGN ON.

Here is a couple pics of Coaster AtomJet.........I wonder what the difference was between the AtomJet and the SuperJets? Anybody have any?
7.5 lb thrust is almost 34 N.... which is a Low E 1.125 OD x 5.25 in length these were had at the Smithsonian: https://womenshistory.si.edu/object...sm_A19930483000 entry says 6lb thrust..that's still a respectable 27 N .
