Chimera 7 LR 32' minutes, 27 Km, DJI FPV, long range flight around the city, using 60% battery !

Описание: Raw footage of a city tour with the 10.000mah 6s2p samsung 21700-50g2 li-ion cells battery.
As per title, after 27km and 32 minutes, I had consumed less than 6.000 mah on a total of 10.000 available, with the battery voltage above 20volts during load when i landed. I could have easily flight for another 15 minutes and land safely.

Video feed is from the DJI Air unit, i didn't carry the Gopro in this mission because I had the low amp / high capacity 10.000 mah lion battery, where I try not to go over 20 amps of current draw, and in this scenario I couldn't afford 200 grams of extra weight for the gopro and its mount.

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