I crashed it a while back into a freshwater canal. After a week's worth of drying in rice and getting all of the dust out- it was flying just fine and everything was working properly... A few flights later, I could not get a video signal to my phone. I tried all of the deleting the app, re-syncing the transmitter stuff. Then I noticed that the camera light does not come on, also, it does not do the leveling out thing when starting up. Any ideas???
