Got my 4K a week ago and had an awesome first day flying it. The trouble is that it was so easy to fly that I thought I was a much better pilot than I was. The next day I flew, I ended up running into a bridge support and splashing down in the water. After blowing any remaining water, I left it in the case with a desiccant for a week. Put a (new) battery in it today and it looked like I may have escaped with only loosing a battery and the rotors. It did actually lift off, but it was very unstable. Ended up breaking a couple more rotor blades on the rough landing. I have seen many repair shops on the internet, but don't know if any of them are reputable, capable or reliable. Does anyone have a recommendation?
