[Planet News] ATF publishes final rule on model rocket motors

That is good infomation.

However, the rule does not state how many grains you can stack, only that the combined total weight is under the specified limit.

Please try to find it. I have not seen anything on g-load limits for segmented propellant grains. However, long skinny motors are more espousing, heavy, etc. Average thrust gets high, but as long as the optimal nozzle exit diameter is not greater than the motor diameter, things should be OK. The real problem is that it just does not work with large 4" motors using thin 62.5 gram grain segments.

You buy a mini H, or a big G, for that matter (HPR G, as these do exist) and if the propellant weight is over 65.5, it's regulated in a few weeks.

"Easy Access" had 62.5 g grains, but that's gone (in OCT) due to the rule.

I'm surprised how many posters here don't have a clue as to the history of the whole mess, and are now making bogus (uninformed) statements.

No wonder that the "self regulation" aspect of TRA and NAR is in question, as it's clear that many newbies don't understand the "self regulation" that was in effect in 2000!

62.5 was in effect for almost a decade, but AT (the one in Vegas, not to be confused with the one in UT!), got an exception, that everyone else used. That exception is gone.

The world changed on 9/11 for things like hobby rocketry, and many here are voicing the same issues that folks did pre-9/11, but it's got even less of a chance now...

Get a LEUP, a LEUP with storage elsewhere, or sign on to the club LEUP.

I know it's a bitch, as I had (keyword is HAD) an LEUP that expired in June. There was NO WAY I could store a mag in my city, and my "contingent storage" is gone (and he charged for getting/storing a reloaded each time).

I've said for a long time, that the money spent on the legal battle would have been better spent on getting NAR clubs and TRA prefectures to set up legal storage available to club members, and view this was even prior to 9/11, the "Patriot Act", and the "SEA"!

Not the same world today as the one that existed pre 9/11, and the legal battle has been going on prior to that.

Face it, as we now hear day to day about "rockets" being launched across borders.
