"towing" ?
Plenty with cam mounted on top of rudder.
What specifically are you looking to see?
Maybe formation flying with chase plane filming.
I have video from a taildragger towing me in a Grob Glider
https://vimeo.com/57744923 Paraglider pilots play around with towed chase cams. Some build their own, there are also commercial versions for sale. Obviously in an airplane things are trickier. Post your results.
You need a friend with the same plane to get that shot. Towing a camera might work but you have a lot of details to work out. Or get one of those follow the transmitter drones...
