I was flying my hex yesterday and everything was going well.
Pixhawk, Tarot680, 800KV high watt motors, SK40A ESCs, (2x parallel) 4S 5200mah 25C LiPo
Then as I did my fifth and final power-climb I heard something weird, like prop chopping through rough air. Panic washed over like many of us have had such sensations, but I slowly descended and landed without incident.
Now the hex hovers fine as before, but if I punch throttle the left side dips first and the hex oscillates 3 to 4 times. I immediately back off of the stick. Left side will also dip when I yaw left (this maybe important for diagnosing which motor has issues). I did an ESC recalibration to be sure, didn't solve the problem. I think one of the ESCs may have been damaged somehow. There is no "magic smoke smell" or scorch marks and all connections are still secure.
Here is my log for some gentle flying with a few attempts to cause the wobble (not sure what time).
Any idea what my issue may be? Any tips on how to diagnose it?
