What is the best way to mount a shock cord to the motor tube, only having
almost a half inch of centering ring? I was thinking that there is not
enough ring there to support an eye bolt and want the masses opinion before
I continue.

Hey folks, got a problem with my MAD...I think.
What I would like to know is if those with the MAD kit assembled without
modifications with the standard 1000uf cap and 9V battery could do some
measurments for me.

Found a couple of interesting items on eBay:

  I'm a BAR (for the fourth time), except now it's different. I have a
2yr old daughter who attended her first launch yesterday. She had a
great time watching us launch and even rocovering rockets that were
close enough for her to run to.  I let her press the button a bunch of

I've posted the stats on the FlyRockets web site clickthroughs. This is
tracking each time someone clicked on a link in flyrockets.com to go to a

...I bet, if each launch had been given a "5 count", instead of a
"10 count", the whole show would have gone a lot faster.   ;O/
Which brings me to wonder...  maybe this is a regional thing,
like "coke" vs. "soda" vs. "pop".

Discovery on to 'discover' that it was not aired north of the 49th.

tape the 3 hour show that might be willing to help me out? I didn't ...

With all the rocketry PR going on, I thought it would be a good idea to

I am pretty sure that I know the answer to this, but thought I'd ask

Even the SIAR has been effected by the Rocket film, during the last week, we've
had 4 new members from the AV area join the list and one OLD member from the
70's find up again and he's back too.

With regards to the 62.5g limit, is that per grain or is that the
total weight of propellant in the rocket?

With the enormous Udvar-Hazy museum opening in a month I'm wondering if
someone in the DC area can see if flyrockets.com can be displayed
somewhere in the building.  They will have dozens of static rocket
displays, and in time, millions will go through it's doors from all over

The last time I launched a rocket was in the 60's. The other day I saw
the Discovery Channel and had to wipe the drool!
Ok, so I'm back to rockets.
I also noticed a BUNCH of people who would instantly qualify for

Ok,
I picked up a Quest X-30 at the newest Hobby Lobby here ($14.95) and I was
wondering if anyone here in rmr land has built and flown it. Upon inspection
of the package, I find it will be a different kind of build from the usual
