AP Yaw Force 
+/- then 00 to 80. Raw force number from servo, 
+ meaning that a force is being exerted in the 
rightward direction against the servo. 80 is 
theoretical maximum before slipping. Always 
reads zero when AP yaw not engaged.

AP Yaw Position 
+/- then 0000 to 9999. Position of servo output 
shaft relative to that at power-on, in steps, + 
meaning in the rightward direction. 800 steps 
represent a full rotation of the output shaft. 
Outputs "XXXXX" when not available.
