New parachute design by Linda Mullen (AD4BL) - the heart of our recovery system.

 

We are switching from a single strand copper piano-wire antenna to a flexible coax antenna system which is more forgiving of in-flight situations. Hopefully this solution will help eliminate problems with antennas getting ripped off.

Wanting to see how we could keep a capsule warm, we experimented with a variety of bulbs and discovered a 5W or 10W spot light run off a 12V "AA" battery pack could keep a capsule above 50F for 4 hours even when it was minus 35F outside. Time/temp graph shown.
