If Part 107 requires you to be flying for "fun" as was mentioned in another thread, does that include involved or complex planned videos that are not done with any commercial intent? I have a video I'd like to do about gravel pits, flying over many of the local gravel pits that are used for construction projects, comparing them and commenting on their importance and methodology. It is purely for my own enjoyment although I will of course post it to the net. I do not have enough followers that it would be monetized in any way. I think it would be no different than many of the videos I see, albeit a somewhat odd subject, but these rules do get a bit tricky and inasmuch as I have not yet decided how to handle the idea of whether I'm going to ask for "permission" from the owners of the pits, I want to know I'm on firm ground with the F.A.A. in all regards.
