You should adapt the file to your transmitter. Use 2000 for min *and* 
neutral in the radio XML file if this is the value you measure.

There is no direct relation between the values of the radio transmitter 
and the servo values.
In manual mode, RC values are translated  into *commands* (according to 
the rc_commands section in your airframe file). Then, commands are 
translated into servo values (according to the command_laws section).
These _commands_ intermediate allow you to use different transmitters 
without modifiyng your airframe file.
