Does anyone know how severely vibration can affect a capacitor's
ability to regulate voltage?  (i.e. how much the voltage can deviate
as a function of vibration)  What types of caps are better at
regulating voltage under high vibration?

    I know a lot of people have been complaining about the availability of
Easy Access motors.  I'm here to tell ya that Great Lakes just got a HUGE

JMRC launch at Gumbert field:
MAN, the rocket gods were pissed off today....  So much hardware reduced to
scrap.  An E9 in an Estes CATO'd.  A Level 3 attempt came in ballistic.  A
separated booster came in without a chute.  The club 'project' didn't get off

thought to have vented actually was still full.  The local bomb squad
insisted on emptying the nitrous tank for no good reason.  There was black

rocket went BANG and his balls went TWANG and he found his arse in his

Sorry for probably stupid question,
how important is the shape of nozzle? Let say this way: if just hole of
right measure gives x meters of height, how much will the "righ-shaped"
nozzle will add?

In a recent purchase of Pro Cell batteries that were marked with a March 2006
shelf life, one needs to check the voltage on these to make sure they are above
8.6 volts. Over the weekend i used one in a reliable altimeter that had over a
dozen flights on it, and after the drogue ...

  I'm just wondering if anyone has made up a set of RockSim files for

trouble of making my own...  :-)
