Hi Sergey.
Now that is along flight time for a rotorcraft!
I don't think that your sensor is wrong, i have yet to find a battery that delivers its
stated capacity.
Every cell i have tried usually fall short of its advertised capacity by 10%

Hi guys!

Well, I finally done the new flight time record with my octo frame under normal outdoor conditions.
The result is 129min 37sec. Well, it's not really way too longer, than Ferdinands record, but the flight conditions wasn't very good today. Partially was pretty windy.
The wind once even dropped my timer down from the logging installation box.
Looks like the NCR18650B cells in my battery are a bit old. Not sure if my current sensor is 100% precise, but despite of the theoretical capacity of 23800mAh, or, according the seller:
the minimum capacity 3250mAh x 7 = 22750mAh, it gave me only 20230mAh.

The attached logs are in rar file.
I'll upload the flight video on my youtube soon.
