FPV tests in Fairbanks, Alaska, with DJI Phantom and a 100mw 5.8Ghz transmitter / receiver package from ReadyMadeRC.com. Camera is GoPro HERO 3 with video out cable. Ends with a crash into a tree (sparse branches). Surprisingly, there was no damage to the quadcopter, and even the Graupner carbon-fiber props were fine (!).
