I decided to conduct 5 tests with different methods of mounting my GoPro to my TBS Discovery.
All flights were roughly the same length and flight pattern. Also all tests were carried out within 15 minutes so no change in weather.
Shot at 1080p 60fps in GPS mode with a weak signal.
There is not a huge difference between any of the results but I think its safe to say the earplugs and elastic bands are for the win. What do you think?
