"Not sure what you mean by "boot each motor up on servo tester to b sure", can you elaborate a bit?   I think they are all setup correctly, I have calibrated the ESC's as per the guide."

"Could it be that you have the Yaw trim off center on your TX? (This is a common problem seen at local hobby shops) I am not sure what Mode you operate in but could the TX have changed modes or otherwise gotten crossed up? You mention changing radio…"
