Just wanted to through my hat in the ring as a commercial rated pilot, part 107 commercial operator (UAS instructor now, yay), and hobbyist. The regs here in the US are a little bit clunky, especially with the non commercial use of unmanned aircraft now falling under FAR 101 there is a little bit of wiggle room. Best practice is to remain below 400' agl. I know this is rather limiting to those of you who are wanting to do long range/high altitude/sailplane flying but there are reasons for the regs. With roughly 100' of vertical separation there is a decent buffer zone between manned and unmanned traffic which keeps both parties safe. The reality of the situation is if you're flying through a camera you simply do not have the spatial awareness that you do if you're sitting in a cockpit. You may never see the manned traffic you're about to collide with and you do not have right of way over a manned aircraft with the way that current regs are written. I won't say that you're being irresponsible for flying beyond line of sight or above 400' (for hobby use ONLY) but you are assuming a lot more risk when you do. It is the responsibility of every airman to see and avoid traffic to avoid conflicts, and in their current state hobby grade aircraft DO NOT allow you to do that. If you're blasting around in clouds like that you're also going to be dealing with IFR traffic, which can also be in a state where see and avoid isn't possible and ATC is necessary to avoid traffic conflicts. ATC can't see you and consequentially can't vector the manned traffic around you. Basically what I'm trying to get at is, please be smart about the way you fly. There are lives at risk when you operate recklessly, and the controlling agency will throw the book at you if you mess up. The best way to avoid issues is to fly within the guidelines provided. If you have an altitude restriction it's not just there to restrict modelers, but to keep manned traffic separated. I'm 100% on board for modelers getting use of national airspace, but you have to recognize that it's a 2 way street and that airspace restrictions are there for a reason. Fly safe and smart and there won't be any issues, but if you're knowingly operating in a way that you shouldn't then there will be trouble for you. Use your head and make sure you're not encroaching on other airspace users. Fun is important, but safety is more important.
