Hi All,
i tried flying Hexacopter after Roll axis tuning,there i observed jumpings after 15 min of flight and currets are going up & down.
i tried without tuning too but ther didn’t observed any vibrations or jumping, i have provided log link below,can someone suggest me how to troubleshoot this issue…
It’s hard to say what is a cause and what is a symptom.
First thing I would suggest is setting up a notch filter. There’s a lot of noise in the motors, and it becomes amplified with stick inputs. It seems to get worse towards the end so could be a heat issue as well.
Set the following then do a short test flight. Just fly around for a few minutes is enough.
INS_LOG_BAT_MASK,3
INS_LOG_BAT_OPT,4
The compass could really benefit from a MagFit calibration, but there aren’t enough turns in that log to get a really good data set. You could try these, but a flight with some figure 8s would be better.

If possible, and IMU temperature calibration would be a good idea if you’re going to fly for longer durations. That’s hard to do once it’s built.
My biggest suggestion is to use the Methodic Configurator. It may have saved you from a lot of these problems.How to methodically configure and tune any ArduCopter
