FPV Long Range - Mountain Surfing in the Alps in 4k - Chimera 7 DJI

Uncut footage of a mountain climb, ridge surfing, couple of dives and then back home. I solved the vibration issue on the Chimera 7 LR, in the end there was an unbalanced motor, simply replacing it solved the problem.

9.3 Km total travel distance, 11:25 flight time, 3.000 mah used from the 6s2p 21700 samsung-40t 8.000 mah li-ion battery pack.

Video feed is from the Gopro Hero 5 Black.

The video overlay was made using Dashware, joining the logs from the goggles and the opentx telemetry. Credits to Drone racing Hungary:
