X20/X20S and Ethos v1.0.11 User Manual
To add elevator compensation to the butterfly mix. the Weight parameter for the Elevator
must be changed to a mix which in turn calls up a compensation curve.
Define a curve EleComp as a custom 5 point curve.
In this example EleComp has initial values of -12%, -10%, -8%, -5% and 0%. If your
aircraft does not have an elevator compensation curve specified, these points will need to
be determined empirically.
Next we define a high mix which will convert our compensation curve into a variable
value suitable as a weight in the Butterfly mix. Use a Free Mix, with throttle as source
and attach the curve EleComp.
