I have a Quest 'Whiplash' rocket with which I inherited and have been dying
to see launched again.  The launch controller has a plastic push-button
trigger which houses a single rectangular 9V battery.
I have just bought 24 inexpensive AAA batteries.  I know if I need to I can

So far the news from Balls 2004 is the 4 cluster O rocket cato'ed.

Other than a few times fins blew off and things took an unexpected turn
of two the worst thing done, intentionally, was to glue an A motor to
some fins and with an orange Elmer's Glue cap for a nose cone.
All motor, no stability.  Flew upwards about 50 feet then began the

I'm planning on launching some minimum diameter 29mm and 38mm rockets on AT
black jack motors.  It appears that RCS doesn't make long delays for that
propellant type.  Just short and medium (6sec. and 10sec.)  My sims say to use
14-16 delays.  I don't have an altimeter that fits in ...

It's not a current news release but I found this while dredging Google:

Now, of course these guys are talking Space Shuttle sized boosters but I
thought I might see if you guys here knew, cared, thought about the subject.

Congratulations!  After receiving 94 votes, we have a winner!
I have included all the points (1=3 pts, 2=2 pts, 3=1 pt) as well as
the ranking.  Ranking was only needed for one tie break, but yields
interesting results.  Does anyone like the idea of only using Ranking

Can someone explain water rockets to me. These aren't the 2 liter
bottles  you put water in and pressurize with air are they?

Suddenly, my old applications like wRASP will only run about 10 seconds
before shutting down. I haven't done any updates or changes to my XP home

Anybody else notice their new ad in the recent Sprocketry?
The plot was nice and wide --  I actually liked it!  :-P

 I was packing the toys up for tomorrows launch (YIPPEE!) and was
looking at the different casings I have and got to wondering about them.
Such as except for length there's no intristic visual difference between
my 29mm's that are meant for G's while the other for H's. And ...

This is a topic we've discussed from time to time but it's not beyond a callback. At least
I don't think so. Besides, this is my post  :-)>
I have minor issues with some terminology.
Specifically, the term "fuel" - to describe solid rocket motor propellants - is incorrect.

First off, thanks to those of you willing to help out a "rocket moron" like
myself.
I am completing building of my first kit (Sizzler) with a Big Bertha waiting
"in the wings".
