Servo 180º

Hi,
I am wondering if it is possible with Deviation to rotate the servos 180º instead of 90º without any external servo travel expander or hardware modification. I understand it is only to decrease the pulse wide below 1 ms and increase it above 2 ms. Is that one hardware limitation in the receivers or is it possible to solve it by software?
Thanks and regards.

Hi,
AFAIK the pulse wide is under sole control of the RX.

Thanks for your answer. Ok, understood. Then the cheapest solution is to add two resistors into the servo.

If you click on the channel you can raise the maximum travel percentage and get some more travel that way.
