I am a recent BAR, having come back to the hobby at a ripe old age.(Never
mind)  I am wondering if anyone has any idea where I can find info on
building a Barometric altimeter.  As light and small as possible, of course.
I am hoping that some manufacturer has an inexpensive, one ...

Office Depot, of all places, is blowing out several X-Acto items. In the
Danville, IL store there were about a dozen 100 packs of #11 blades for $8.00 a
box left after I got my lifetime supply. Other blades and several handles
similarly discounted. These were marked down in steps so ...

I was at the Tripoli QC web site today, and the last launch I saw mentioned
was in Nov 03.  I'll be coming up there for the next few weeks, and was
wondering if there are any launches, or if they lost their fields.
Thanks

The banquet lasted until 12:30 so that's why this is a day late.
Another day of beautiful weather. The sun was brutal and nary a cloud in
sight. The air was still, and thus many of the M and N motors tickled the
waiver.

I'd like to thank BRS for putting on LDRS.  From the point of view of
 a spectator/vendor-type, I found it to be pleasant and well organized.
 I think BRS deserves a sound "atta boy" for putting on this event.
 The food concession, run by the 1941 H.A.G. was truly grand.  The

Where should the center of gravty be on the estes V2 rocket?  Right
now it is at 11.75 inch from tail of rocket.  That is about 35% up
from the tail.  That is with the motor.  I am guessing that that is
not very stable.  I downloaded VCP, but I dont know what Im looking

Greetings All,
I need to line up authors for this year's NARAM event coverage articles
in Sport Rocketry magazine.  If you are interested in volunteering to
write the coverage for an event, please send a response to

I want to use a PML co-pilot to detect apogee in a rocket which is
entirely conical, i.e. no parallel body tube.
I understand that ideally I would vent the sensor at least one caliber
after the transition from the nose to the body, but in this case I

I'm trying to work out how efficient a mechanical water rocket would be,
and I'm a bit confused about the theory:
Rocket 1 accelerates 1Kg water / Second of exhaust to a velocity of 20M/S
Rocket 2 accelerates 0.5 Kg water / Second to an exhaust velocity of 40M/S

I'm getting back into rocketry after many years ago launching a bunch
of littlish rockets. I've been launching some Estes kits and rockets
built from Estes parts in on D's, and want to get into the mid powered
E/F/G range. I'm checking out the kits from Aerotech and really like

I am organizing an elementary school rocketry program.   I have
purchased three Estes SnapShot (RTF) kits to use.
I have experience using midpower Aerotech rockets, but have never used
any Estes "camera" kits.  I plan to replace the parachutes and shock

Did anyone beat Geoff?

I have had rockets spin with video on them, and rockets that stay very
straight, like on rails.
Besides the LOC Bruiser I flew straight as an arrow, in my last video post,
I have a LOC I-Roc that stays straight in flight as well.

Oh, I have such a pain in the diodes all down my left side.  The first
 five million years--they were the worst.  The second five million years,
 they were the worst also....
Anyway.  After much shuffling, and severals changes-of-plan, it looks like
