Quad250 in 0 Celsius freezing temperature

Quad250, did change autotune pitch Pid D gain. About 30% less. Better now, but not good. These Esc's are so bad. Too much delay Tau 57,74. Cannot make this quad fly better with these Esc's.

It was cold weather 0 Celsius, freeze my hands. But could try 3 batteries today :)
