Default RE: New Servo - Futaba BLS171HV

To illustrate how fine you should be able to set the neutral and end points consider the following:

Assume your servo throw is set for a total of 100 degrees (+/- 50) with the full throw of the transmitter range which we'll assume is 2000 steps. It is capable of 2048 but we'll assume some is used for trim.
If you divide 100 degrees by 2000 steps you get .05 degrees per step.
This is 5 times better than the .25 degrees per step that the programmer allows you to set.

My assessment is you could probably match servos well enough for two ailerons but not for two elevators or two servos on one surface. It means you can't have interchangeable drop in servos if you replace one in the field. It is also a shame as it negates an advantage of the S.Bus that would allow you to connect multiple servos to one channel and eliminate Equalizers or Match boxes.
