Been Googlin' engines, none locally, at least not the ones recommended
by the folks I bought the kits from.
If anyone here has to buy engines online, where have you found to be a
good source?

Hey all,
We did our 1st ever rocket launches today...(We being me, my 7 yr old
daughter and my 5 yr old daughter), and with some hitches, it was a success.
We had built a balsa model over the winter and it was ready to go, so we set

Yesterday was a wonderful day for launching rockets around here. So my
brother and I set out to launch the only built and non-damaged rocket I
have on hand - Estes' Snapshot. We did two launches and the second,
which was this rocket's fourth launch, proved to be too much for the

Been thinking about a 'BigRedBee'.  I was wondering where a good place
to put it would be?  On the rocket I mean.
I clicked on the link for building a 70cm beam. I think a 5 ele beam
is a little overkill.   Look here:

Is there a way to more accurately determing drag without have a degree in
theoretical mathematics from MIT?
Just running some sims and wondering what the Cd actully is...0.75 seems to

We just wanted to say that Verna & I hope all the U.K. rocketeers and their
families are all safe and doing well after the cowardly attacks on London

While channel surfing during commercials, I hit upon an HGTV segment
featuring color-changing paint.  Paint changes color due to
temperature.  One of the neat things they had was a faucet painted with
the paint.  Hot water made it turn red, cold water made it turn black.

has anyone who has flown high power requested getting a TFR (temporary
flight restriction) for their launches? the military ATC asked me about it.
I've never had one, but I've never asked for one.

Can anybody tell me the influence of gravity on the trajectory of a bullet
when the aim is to shoot as far as possible?
To put it simple, if i shoot a bullet from a gun on earth or on the moon
(places with different gravity) does the angle, in order to shoot the as far

Thought some of you might like this story about my youngest and newest
modeler.  After a recent trip to the hobby shop my 13 year old son
came home with a new plastic model to build.  My 3 1/2 year old son
was presented a new foam glider.  The glider was fun but the younger

Yes, yet another post, this time about airbrushes.  As some of you may
recall I bought a bunch of krylon paint.  My returned glossy stuff is
another issue....however....
I've found that I like building and especially painting / finishing
