Interesting. I never knew that this was possible, and upon reading it, I am not sure that it is necessarily a very good thing.
I believe that by default, a Victor looks for a PWM pulse corresponding to 127 as neutral, 255 as full forwards, and 0 as full backwards. By recalibrating the Victor, you will adjust this calibration, which will give you better performance for that particular output/victor pairing.
However, this problem can be fixed in software instead of in hardware, leaving all of your Victors in the same known configuration. You can program your RC to output the joystick values, find the max and min, and write a little function to scale the joystick values to reach 255 and 0. This lets you adjust joystick behavior in software, and is very easy to see and change.
Maybe someone with more experience knows something I am overlooking?
