Ethos v1.5.7 and X18, X20 series User Manual
Snap Roll
The snap roll is an auto-rotation maneuver in a stalled condition. During a snap, one
wing is stalled while the other is accelerated about the roll axis. This creates a sudden
roll-rate acceleration that you cannot obtain by simply inputting aileron. To achieve
this condition in a model, several inputs must be given, including elevator, rudder and
aileron. For example, you can perform an inside left snap by programming the mix to
simultaneously apply up-elevator, left rudder and left aileron for 1 to 2 seconds.
Recover from the maneuver by neutralizing the sticks and immediately adding right
rudder to correct your loss of heading.
Throttle to Elevator
This mix allows elevator compensation for planes that change pitch on changing
throttle.
Please note that the mix has a built-in offset so that the mix output is zero when the
throttle stick is at its low position, and at maximum at the throttle stick high position.
This offset is disabled when a user curve is added to give that curve full control.
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.
Please note that the mix has a built-in offset so that the mix output is zero when the
throttle stick is at its low position, and at maximum at the throttle stick high position.
This offset is disabled when a user curve is added to give that curve full control.
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.
