you all had me very nervous...ejection failure/time delay disasters with
the 29/40-120rms.

so an hour before launch i prepped an f52-5j, even though the grid sheet
says -8.  i figured with the bonus i would be ok.

another problem got solved cheap today when i went to radio shack to
look for parts to make a relay launch controller (still trying to figure
it out).  i saw a 12v lantern battery for $9.99, beats spending money
for lead acid and a charger by over $50.  

went back to the field i've been using the last couple of sundays, 7:30
pm, temp in the 80s, clear, very, very light wind.  recruited a guy i
know from the neighborhood swim team to come with me and check it out.

set up the mantis launch pad, connected the igniter to the at
controller, attached the battery, got a strong contact signal, pushed
the button and...

initiator blasted off great, not a lot of smoke, fired straight up, had
to be over 1000'...chute deployed at apogee, delay seemed right on 5
seconds...rocket drifted south east...i was in trouble...headed for the
road...when i figured it was in the street i took off running...i saw it
in the middle of the street...cars were swerving around it...one last
car to go before i could get it safely out of the street but it got hit.

fortunately it didn't get crunched...all that happened was the nose cone
got slightly creased but should be ok...also lost a tip of fin when it
hit the pavement...also a fin popped out which is easily glued back in.

i loved it, it was exciting, saved it from getting run over...hope to do
it again...did not see a problem with this rms.  i just need to figure
out a place big enough to handle recovery.

I also just finished building and launching an Initiator..  Great
Rocket!      First flight on an E 15 (I think..  Too e***d to
rememeber now...)    Flew great!!!   Landed a little rough...  Broke a
fin off..    It had a seven second delay which I have decided is too
long for that engine....    A little epoxy on the fin and she was all
ready to go again...  

Second launch was with a G64 (Blue Thunder)...  That was quite a
flight!!!  At least 2000 feet..    I lost it on its way up after the
engine cut out..  Getting kinda dark...  Luckily there was a guy
walking his dog (which got the ***scared out of him when it
launched!!!!) that saw where it was going...  

It landed right in some guys front yard, scared the ***out of him
too...!      The Initiator Rocks!

you know you re right...i checked this month s sport rocketry (after i
got back from firing it) and i didn t see it listed...what s the deal?
i bought it at a hobby shop.  5t makes sense since there was no
smoke...it worked fine anyway.  what happened to this motor?...like a
say it was on the rack at kingsway hobby like no big deal...

What happened was, very simply, Aerotech apparently never bothered to get
it tested and certified, but put it into the distribution pipeline
anyway.  If you still had it, I'd suggest you contact Aerotech and demand
a refund or replacement with a motor you'll still be able to use after
June 30 -- which is a pretty short list, and let them know how displeased
you are that they're selling you illegal fireworks labeled as model
rocket motors.

Because that's what they are.  If your local authorities wanted to, and
knew what they were lookinga at, they could arrest you for possession of
an F52 just the same way (and under the exact same law) they'd use to
bust your for having a dozen skyrockets in your closet -- assuming, as is
likely the case, that skyrockets are illegal in your area.

In fact, since most states now have wording about model rockets that
parallels or copies NFPA 1122, it's probably illegal to sell the F52 even
if it's legal to buy skyrockets at the local fireworks stand in the next
few weeks...
