[Here's a primer on "reversible" http://142.26.194.131/aerodynamics1/controls/Reversible.html] Having the powerful squared effect can lead to "negative" training, i.e. the wrong "feel".
Here's an example file: Input/Joysticks/Microsoft/sidewinder-precision-pro.xml
The aileron axis is squared: <axis n="0"> <desc>Aileron</desc> <binding> <command>property-scale</command> <property>/controls/aileron</property> <squared type="bool">true</squared> </binding> </axis> The elevator axis is squared: <axis n="1"> <desc>Elevator</desc> <binding> <command>property-scale</command> <property>/controls/elevator</property> <factor type="double">-1.0</factor> <squared type="bool">true</squared> </binding> </axis> The rudder axis is not squared: <axis n="2"> <desc>Rudder</desc> <binding> <command>property-scale</command> <property>/controls/rudder</property> <factor type="double">1.0</factor> </binding> </axis>
To model small nonlinearities that can occur w/ push rods and control horns, I think an exponent smaller than 2 would be more appropriate, if used at all. Instead of "squared", I suggest we add an exponent tag:
<exponent type="double">1.2</exponent>
which would lead to the effect:
surface position = (stick position)^1.2
