for me maintenance of my drones ,has always been an important part of drone ownership
apart from the safety aspect, but also from keeping the drone flying reliably for as long as possible ,without damage to it, or anyone, or anything.
of course no matter how fastidious you are ,there is always that one occasion, when things go wrong ,through no fault of your own ,that is the definition of an accident ,an unplanned event ,and all we can do is our best, to try and prevent such a thing from happening,this applies not only to maintaining our aircraft ,but also to the choices we make when we fly them as well
