TBS Discovery Epic 7km FPV Flight (Full version)

Yesterday I improved my personal distance record in long range FPV (Long range for a multirotor, of course) with my TBS Discovery. Now it's 7 km :) I believe this is the farthest flight ever made with TBS Disco. Next time will try to reach 8km. Enjoy the video!
