Ethos v1.5.7 and X18, X20 series User Manual
Rudder to Elevator
This mix can help when there are coupling issues. It can also be used for adding a V-
Tail differential function.
Throttle to Elevator
This mix allows elevator compensation for planes that change pitch on changing
throttle.
Throttle to Rudder
This mix will help the plane fly straight when at full throttle; it’s generally needed
when flying a vertical up-line.
Test mix
This mix is great for soak testing servos. It includes a range setting, as well as Slow
Up and Slow Down.
Offset
The Offset mix is used to add a fixed value to the mix when an offset is required. A
common application is for flaps, where the servo horn is offset in one direction in order
to maximize the downward flap travel. This results in the flaps being in a half way
down position at servo neutral. The Offset mix can then be used to bring the flaps up
to the ‘surface neutral’ position when the flaps mix output is zero.

Flight mode
This mix is used to provide a flight mode control to the FBL controller on the Heli. It
may be Normal/Idle Up 1/Idle Up 2 or for example Beginner/Sport/3D.
