Pixhawk Help Motor Sync Issues

Hello all,

I am trying to fix an issue with some of my motors. Some of my motors don't seem like they are starting evenly or at all on my X8. I can here the clicking sound of the ESCs giving power to the motor. Not sure what the issue is.

Without any propellers, all the motors work flawlessly. Everything powers up and nothing is out of whack. When I put on the propellers, some of the motors have some issues starting up (one or two motors). Even when I add a little more power, they don't seem to be kicking in.

I've already calibrated ESCs "all together" and individually, no luck. 

Here is a video of my issue:

Can I change the start up/idle speed? Do I need to use only signal cables? Soldering Joint issue?

Thanks!

  • Moved motor to other areas.. Still doesn't work. I'm thinking it maybe a soldering problem.
