This user has 20 videos of the topic, this first video I point out shows some flying plus a quick demo of the equipment he uses including his goggles which control pan and tilt of the camera on the vehicles!!!
Now try telling me this isn't every lads dream
Not sure exactly how much this sort of setup will cost. Obviously need good spacial awareness so you don't get carried away and fly out of radio range.
Some of the videos using RC cars too.
