Hello,

My octox (coax) yaws at the takeoff, I can yaw back with the controller but there is a constant yaw behaviour. Any ideas?

Some ideas without looking at the log:

  • “yaw imbalance” caused by twisted motors. Search this forum. lots of posts about this
  • the yaw trim of your TC transmitter is off-center.
