you all had me very nervous...ejection failure/time delay disasters with
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.
