Just had my first of what will most likely be many beginner crashes today. I had a successful flight in what I consider a bit too windy for my experience. During the landing sequence, a quick gust of wind upended the copter and flipped it when the first to legs touched the ground. I was flying in an open field will low cut grass on a very soft ground due to heavy rains. Upon inspection, I noticed only one very small divit in 1 of the rotors... I mean small like half the size / width of a pencil tip. Do I need to swap this out? If not, what is a good gauge to go by as to when a swap out is necessary?
