Looks like fun. This device keeps a camera pointed at a RF tag
bearing target. You can mount the cameraman on one glider and
point it at another.

has anyone tried this? just aiming the camera is the hardest thing
to do in air to air shots...

as to read from that site: "Film yourself with SOLOSHOT, the Robot
Cameraman. You wear the Tag, and the Base automatically pans, tilts &
zooms to keep you in the camera's shot up to 2,000 ft. away for over 3
hours. No line of sight required."

"up to 2,000 ft. away" may be not enough when you're going to take air
to air shots, I think.
