"We would also enjoy to make partnerships with hobbyists operating high tech airframes (like fast jets or long endurance motoglider or extra light models). I offer a beer to the first < 150g, >100m/s or >6 hours endurance paparazzi :)"

Does > 50,000 feet count too? ;)

We are planning to send a glider up on a weather balloon, and have it fly itself down again. Coding autopilots is by no means our strong point, and it needs to be very stable (otherwise we have a pretty effective rock falling out of the sky).

Redundancy is the key I suppose. For example, we can use pressure sensors for altitude and airspeed. If they fail, we can switch over to the GPS. If everything fails, we can have a separate chip to restart the main computer. If that fails, it can just release the parachute, and somehow report its location to the ground station.

Has anyone run/willing to help with running Paparazzi on a glider? Running the ground station via packet HAM radio wouldn't take much modification would it?
