I have the phantom 2 with the H4 3D gimbal and gopro 4 black, Black Pearl and Immersion for TX and FPV as well as the mini iosd. I would call myself an intermediate level flyer and practise down a local oval in a small town, no objects, lucky if a jogger or someone walking a dog, mostly to myself and absolutely no powerlines. I practice figure 8's, HL and CL. I follow all the, I believe, to be correct pre flight procedures, checking props,calibrating. Today I flew about 100m from my usual takeoff spot and did all the above. There were some dark clouds in the distance and it was dead still for a change. About 10 mins into the flight I heard thunder and activated HL and on the way back there was a lightning strike some distance away. Time to pack up and go home! The phantom appeared to be coming back and there were 3 quick strikes in succession and suddenly loss of control as it started heading east of me. The OSD was getting some interference but still visible as well as the video feed. I switched to ATTI to try to orient back towards me but no response to any control. Meanwhile from dead still a savage westerly was carrying it further east. Switched back from ATTI to gps and again HL (realise this was a panic as must have lost GPS anyway). Lost line of sight (max distance via NAZA is 750M) and it headed out over our small town. So, in the car and try to follow the general direction. A post on a local page of our small town yielded a lot of response as someone saw it fly over the local pool heading east. A LOT of bush to cover in that area and no idea of the distance it could have gone, last indication from the FPV was 58% battery.
