Group project 5.5" Polecat Thumper airframe built in the Quay West Suites in
Brisbane, Australia, during LCA 2011 by Bdale, Keith, Mike Beattie, and
Anthony Towns. Flown at QRS club launch on an Aerotech J315R 54mm 2-grain
motor.
We believe this was the first time ever that an airframe flew with redundant
TeleMetrum boards! Test firmware in the sn 56 v1.1 board failed to sync with
the GPS chip for some reason, but both boards apparently fired their charges
exactly when expected. Sadly, we were stuck friction fitting the nose cone,
and observed the main deploy after the secondary altimeter's apogee charge
fired. Fortunately, it wasn't that high and the wind wasn't too strong, so
everything was recovered in good condition!
