My P2 is behaving very strange. It all of a sudden starts to fly away sideways in a very fast speed, the best thing i can do is to try to get it up as high as possible before it hits something. Its very hard to control the P2 sideways when this happens. It didn't happen before, it has been like this for about the five last flights. I had a light crash earlier without any visible damage, I'm not sure if this started to happen directly after the crash or not? It often happens almost directly after start. Sometimes it gets better after a while and sometimes not. I have good GPS reception with about 11 satellites and the lights on the P2 is green. Anyone have any ideas what it can be and a possible fix for this?
