I recently lost a small Syma X5C-1 with out a gps. I was in the mountains and have searched high & low. The needle in a hay stack becomes a drone in a forest. With the GPS on a P3 will it make this task effective? Is there a tracker or even a chirp device I could use? I have diminished confidence in my flying abilities and am concerned about my new higher priced investment. But still haven't cried......
