Safety thoughts.

Some times in every drone pilots lifetime, you lose a drone, sometimes pilot error, sometimes a technical glitch, sometimes the answer is not as obvious. if you are lucky, you can find it again, sometimes it goes to where you can't recover it. Other times you have no idea where it went. For the smaller ones it's a minor loss, but when you get to the bigger (350mm+ size) you have more of an investment in the unit and you want to invest a lot more into finding it. There are pet and car locators/Trackers that could help you find where the silly thing went. Before you put more gadgets onto it, this might be a good idea.

And speaking of being prepared for the worst, most of us fly near a body of water at some point. Some of us live near the ocean. Some near lakes or rivers. Heck, even a large duck pond. Unless you have the type of Quad that is designed for water, these things sink, Quite rapidly from my research. If there is any real chance of losing it in the water, perhaps adding some sort of floatation device would be a good idea. It could be as simple as some styrofoam or part of a pool noodle. Lightweight, cheap and depending on what you use and how you shape it. there shouldn't be an effect on performance too much. But it could be something that salvages at least some of your investment.

I have even seen some recovery parachutes for Quads. (if you get one, get the largest one you can fit. They will slow it more and reduce damage).

Of course all these things have a cost in performance. There is an old rule in building radio controlled airplanes. It will do what you build it for. If you build it to really fly, it will do that quite well. If you build it to survive crashes, then that is likely the only thing it will do very well.

many of us have prop protectors for a while when learning, R/C helicopter pilots often put radically extended skids on at first. and chances are that most of us had something less than a V12 Ferrari for our first car.

I leave it to you to decided what is important and what is worth more to you, but I can tell you that you will get very little if any teasing if you are a little overcautious at first rather than trying to overfly past your abilities and losing a lot of craft.
