  • Radio! Damn it!
    Some old mixes in my radio were the cause of my problems.

    Thanks guys!
  • Thanks for the replies.

    I have tested with two new lipos so I think they are not the problem source.

    I have checked ESCs with a programming card... everything looks normal.

    I have triple-checked CW and CCW props

    I'm using two different RCs... I will review it!

    Any other ideas?

  • maybe some CW and CCW misplaced?
  • Check your lipos. I had pretty weird behavior like yours and reason was a bad battery.

  • Same RC on both?
    Is power distribution okay on the second quad? Maybe one motor (or a pair) isn't getting enough amps?
    Different settings on one of the ESCs? (timing, soft start?)

    Just throwing out ideas...
