Atomrc Dolphin 2nd flight - testing efficiency

Just a nice relaxed flight with Atomrc Dolphin.
Current sensor scale is off, OSD showed 5000mAh used, but battery voltage on landing was 3.8V and charger only charged 3800mAh back to battery.
So the efficiency was ~85mAh/km with average speed above 80km/h :)

Atomrc 2212-1400KV and stock Gemfan 7042 prop. With GNB 4S HV 6000mAh I can get 80min flight time and 90km total distance.
