Hi guys, Today I was flying near a motorsport area when all of a sudden my PV2+ started descent and I could not control it any more, maybe I just lost battery power, not sure. When I tried to gain height someone passed by and hit the Phantom, it got a good spin to the ground but there was no major impact or visible damage. Since than no satellites appears on the screen and the camera pitch control is not responding. The cause could be the crash or something else that also caused the descent that came before that. I opened the top and looked for loose connectors and made sure everything is in place, did not help. Any idea what can cause such problem?
