First crash in ages, and into a river. I was suprised that the lights stayed on the river water must have been reasonably clean. I let thing dry out for a few days before trying to fly again. It turned on but could not get it to connect to hand set or ipad, and the back blue lights were flashing. I waited a couple more days and it all worked again flew perfectly. but today it’s not connecting and the lights are flashing again, what does the flashing mean? Manual says no binding and i can see inside looks like a red led is on?
