Description

Little shy of 10k but no matter. Went pretty straight with minimal weathercocking toward apogee. Landed 1300 feet SE of pad. Not sure what happened during boost but I was using RTx GPS system. It always had a fix (LAT/LON) and 10-11 sats in view but never saw altitude. Also barely missed landing on the 500 kV power lines - WOW!

MARSA accel altitude was 10329'. Spoke with MARSA mfg. & he stated that the baro is probably accurate since the rocket turned into wind near apogee and acelerometer just measures 1 direction. Also from video it appears that the backup charge fired a bit early (slightly before apogee).

On board video too - this rocket is a spinner - disappointed. Two videos posted, one unedited & the other cleaned up & shortened.

There must be a bug in Insane Rocketry as my flight data will not plot/truncated.

.dat files (marsa) should properly display graphs again. Sorry it took so long for me to fix.

Tim it looks like the charge fired perfect at apogee while banking... Hey and that was a straight u[ flight also !!! The spin is not that bad Tim. Just a few pieces of tape on the fins and it will be much less !
