ESC's enter calibration on Arm.

I'm putting together an x8 and I've run into an interesting problem. First, I can't do the all at once calibration with pixhawk. My ESC's keep beeping as if they aren't getting a signal.

The larger problem is that they enter calibration mode once Pixhawk is armed. I get the constant beeping of no signal when I first start everything up. Then, once I arm Pixhawk I get the confirmation beeps that the new end points have been set. However not all the end points are the same and some motors still beep as if they aren't getting a signal.

Any ideas as to why this would happen?

I'm running 8 KDE 55A ESC's and my receiver is an x8r plugged into the rc port of the pixhawk using the sbus out of the receiver. I'm running the latest beta firmware.

  • Just in case it is useful to others, this is no longer an issue. The problem has to do with the control loop isolation on the Pixhawk hardware, and the solution is simple.

    • No, that is not the solution. I wish it were that easy.

  • Hi,

    Did you solve the problem? I bought the same ESC, but I have not tried them yet. I have Pixhawk too.

    • No, I never got them to work correctly with Pixhawk. I wound up switching to SuperX as my flight controller.
