So I have built up my new gremlin and it was flying fine for a couple weeks. Then I crashed really hard strait into a wall. Now the drone starts drifting really badly and I am not sure what to do. I have it soft mounted, tried recalibrating the acc. What else is there to do. It takes off fine, but as soon as you start flying the drift gets REALLY bad. It is like I am do full stick backwards. I have to use 3/4 stick forwards in order to keep it from flying back at me. Please Help. Thank you very much for your time and effort.
