Did some I2 testing without cam/gimbal (not delivered yet)...
Some full throttle in GPS and Atti, some hovering, very little Sports mode.
Outside temp 4 deg Celsius.
Wind speed 5 m/s
20 m/s against wind, all modes
30 m/s atti and sports 26 m/s gps with the wind
Battery to 10%: 15:35
Second test, a bit warmer (8° C), but very windy (gusts of up to 50 mph): duration to 10% 20 minutes
Hovering test inside to 10% at 20 deg Celsius: 26:08 mins
Seems to me that because the batteries are "open to the air" at almost all sides, it performs very badly in cold weather.
15 or even 20 minutes flying doesn't seem long to me...
As for distance, 3 km without any problem.
