OneShot ESC Calibration

Ok let me start by saying I am really in the dark with what appears to be a very good and capable flight controller. BUT and there is always a but. I have setup my 250 quad with a pixracer, which is running EMAX nano oneshot esc attached to emax MT2204 motors. I have set the pwm-max to 250, pwm-min to 125 and pwm-disarm to 100.

What is happening when I arm the board three of the four motors will start to spin and motor 1 remains stopped. at half throttle they are all spinning , not sure if they are at the same speed. the FC is in stabilized mode. When I shut the throttle motor one stops but the rest still spin at a fairly high RPM for a minute then slowly decelerate to a very slow spin.

Where can I get the data of what signals are being passed to the esc in short how do I go about trouble shooting this issue as I would really love to get my quad out and fly it before the winter arrives.

You can view the commanded PWM values using QGC, or by looking at the log. Which airframe did you select?
