I've thought about this. I saw a radio controlled helicopter toy that was very easy to fly and had a real-time webcam on it that transmitted the image back down to Earth. Don't recall what it was called but it was very cool, around a thousand bucks and manufactured in Saskatchewan. It would make a great reconaissance tool or objective for teams, provided there was a competent pilot for them to "commandeer".
The main issues I see with R/C aircraft and airsoft are twofold.
1. They can be very dangerous. The prop's spinning at thousands of RPMs and could cause injury if it hits someone, not to mention the blunt force of being struck by an object that large.
2. How do you prevent idiots from shooting at it?
