Ouch! :(
Just a thought, many years ago I watched a demo of a BRS for a model plane at
Cosford in the UK. Apparently it was very lightweight but had clever
triggering. In the event that the radio signal (controller to plane) was
lost, the system cut the fuel off to the motor and released a spring loaded
BRS which brought the model down for a vertical but gentle landing.
Could you fit something like this on the UAV for loss of contact events?
It's definitely an interesting thought. Anyone know what size parachute
a person would need to gentle let down about 15 lbs (7kg)? Many R/C
receivers have a failsafe mode so you can trigger the servos to go to
preset locations in the event of a transmitter signal loss. The danger
is probably similar to the danger the full size BRS units have ... if
you deploy the chute at a high speed, you are going to tear your
airplane to shreads.
