Hi,

the values sent to the servos can be displayed with the ACTUATORS 
message. This message is not sent by default. To get it, you have to set 
the telemetry mode of the fbw process in "debug" mode. Two solutions:
 - Add the telemetry_mode_Fbw variable to your settings file (similar to 
the telemetry_mode_Ap entry in tuning.xml file), and set the variable to 
1 (through the GCS) while the board is running
 - Just add

ap.CFLAGS += -DTELEMETRY_MODE_FBW=1

to the makefile section of the airframe file.

If these values are correct, then you will probably have to check the signal
with a scope ...
