A UAV as thermal sniffer? Yikes!-Those things will probably be controlled by
software, written by humans -Forget it.

Instead, rely on million of years of systems testing, bring an eagle along
(would look awful when you open the doors to the Raptor Compartment!)

Seriously; paragliders do this with success:

BTW, I bet if you had a transponder, the UAV would be programmed to
avoid you like the plague!

Oh boy, a whole new game! Hunt down the soaring UAV and "bump" it out of
the thermal (g).

Good idea: get a PCAS unit like the Zaon MRX and use it to find UAVs, grab
it's thermal while it leaves to find the next one! In fact, a UAV could be
considered a remote thermal sensing instrument.

How about carrying small one folded up in the glider? When the soaring
gets tough, you launch it to help you find thermals. It could carry a Spot
so you could find it later it was unable to return home on it's own. The
glider could be carried in a tube under the wing or on top of the
fuselage, or inside the fuselage with doors like a motor glider.

Or ... Forget the transponder: just have Spot send text messages to your
cell phone, so you know where the UAV is. FLARM is another way the UAVs
could be avoided, and eventually they will all use ADS-B.
