Have you all seen the new Ford commercial?  The one where canoes go out of
control?
We must be outraged!  This commercial clearly disparages canoes, and paints
those who travel with canoes as out of control outlaws!  We should start a

Martin updated the website with the latest info regarding launch site
status. May 29 launch is moved to Lucerne. Visit our YahooGroup for

Been working on some software to overlay flight data on video so I
just thought I'd share the results with you guys.  It takes in an RDAS
file and a source of video and you just tell it which frame is t=0.0s.
It would be easy to modify to use other data sources too.

Has anyone heard from Doug Parks or Rebar Rocketry lately?  I've been trying
to contact them for a month with no response.  Anyone have any contact
information other than what's on the website?

  As can be seen by my prior post, am trying to explore dual-deployment
options.  For the past two weeks have been doing searches on low current
ematches to deploy the system with 4Fg powder.  My impression is that
most of the low current ematches like Daveyfire have all but ...

I'm doing some flight simulations for what may be a 'marginal' liftoff
rocket. What's a good value for velocity as the model comes off the launch
rod? It's been too long since I looked at this, but my gut is telling me
that 10 m/s is just too slow.

I'm researching a scale project.  I've always loved the rockets with
multiple external boosters and found that the Delta II 7925 was used to put
MER A - Spirit - on Mars.  Looking to make a large ModRoc to small Level 1
size model - about 1/36.

Acceleration = Net Force Acting on Rocket / Mass of Rocket
Net Force = Thrust of rocket - weight - drag
In the above equation is thrust of rocket equivalent to average thrust?
In the case of a cluster, would you add or  multiply the thrust of the

Well, we now have legal evidence that model rocket engines are not
explosives:

  Want to do a G or < size dual deployment model that uses heavy
cardboard tubes.  Instead of shear pins I thought if clear shipping
tape might be workable to hold the electronics section together to the
upper or lower section.  Also which section contains the drogue or does

NYPOWER 11 is only 40 days away!
We need Volunteers to insure that this event is a stunning success as
it always has been. We even have some NICE incentives for volunteers!

I pulled my Pratt Surefire 12 out of storage today. Hadn't used it since
last May. As some of you may recall, this is the same unit my dog urinated
in about 5 years ago. Well, I ran the system check and what do you know, it
still had 13 volts in it. Two hours on the charger and ...
