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?)

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?
Check your lipos. I had pretty weird behavior like yours and reason was a bad battery.

Just throwing out ideas...
