KCI-1500 from Kaymont (wayback machine link)


Scavenged Styrofoam cooler.


3.6' orange ripstop nylon round parachute with eight 7' lines to the payload. 5" center vent with one 15' line to the balloon. Grommeted cord connection points.

  • SSTV - SSTVCAM from Argent Data
    • Due to technical difficulties, we are NOT flying the SSTV system this time. :-(
  • Digital Video Camera - Jeff's, need to get model/specs
    • Due to this camera causing short-range interference with our GPS modules, it was flown dangling from the radar reflector with just a hand heater taped to it, no enclosure. It worked great! (At least on this flight)

Just the trackers listed above.


2lbs 13.9oz




The camera used 3 AA batteries:

  • Post-flight all 3 batteries were measured at 1.72v (down from 1.83v fresh)

The old tracker ran off of 2 9v batteries:

  • Post-flight both batteries were measured at 9.20v (down from 9.80v fresh)

The new tracker ran off of 2 9v batteries:
