Last Saturday, there was a Minie-Magg drag race held at Bong Recreational

can somebody explain to me why hybrid rocket motors are regulated by the
nfpa? I mean Nitrous oxide and plastic/paper/whatever are NOT explosive as
far as I know. Nor it it considered a flammable solid as it doesn't become
such until it ignites.  I don't think NO2. Sure a hybrid ...

  Speaking of a sequential launch controller.  Has anyone seen
any plans or schematics of a digital launch controller where the launch
controller box sends digital commands through cat 5 or regular network
cable to a decoder box out in the field?  This in turn would send the

I said itwas justa test

Hello, this might sound crazy but I've got some old (around 15 year old) FSI
F7-6 motors laying around.  I'm wondering if these would work in Apogee's
aspire.  The model was built to make the most of their F10 engine, but I'm
wondering if the FSI motor might be close enough to ...

WASHINGTON, District of Columbia USA - The Bureau of Alcohol, Tobacco,
Firearms and Explosives (ATF) published in the Federal Register today a
final rule that amends the regulations to clarify that the requirements of
27 CFR Part 555 do not apply to model rocket motors consisting ...

Since there's been so many LEUP threads here lately, thought I'd toss
another in the mix.  Say I wanted to apply for a LEUP with storage.
(probably never actually will)  What are the requirements surrounding the
storage facility - meaning the building that your magazine is stored ...

What would happen if the rocket (a LOC Stovi) was flown with too much
weight (about 8oz.) in the nose? What is the flight profile of a rocket
with excessive noseweight?

Okay, I've done my Googleing and I know that if I ask a specific question
here I usually get an answer. So here goes. I am looking for a
paper/report/discussion on how spin stability works. Not a heavily laden
math treatment of it. Just some basics. I need to present this to 4th

what does it cost to get level 1 HPR certafied.

Maybe a jobs comming up for me in Seattle, as a Brit my US geography is a
bit vauge.  How far is it to the nearest lauch site?  Do you think getting a
LEUP will be extra hard being a forigner?
Halam.

folks, I'm confused.  Alot  if not most  states have the typical fireworks
exemption for model rockets and model rocket motors... the so-called
recoverable aero models clause..
And now model rockets are regulated by nfpa fire codes....since 1968.

I am looking to buy a large quantity of Micro Maxx Engines (400 or
more) preferably MMaxx 1 series engines but I will take MMII engines.
I am looking to get them for around a quarter or less a pop.
Suggestions ?

Has anyone seen this "recent" bit of information referred to in the
final rule published Friday? If so, who was it sent to and what does it say?

Speaking of rocket fuel (re: onion atricle), can anyone hazard a guess at
the propellant used in katyusha rockets?  The reason I ask is because it
seems like it is a fairly long burning engine with "moderate"* levels of
thrust - just what one would want for a rocket glider.  Of ...
