X20/X20S and Ethos v1.2.10 User Manual

6. How to configure a Butterfly (aka Crow) mix

Butterfly or crow braking is used to control the rate of descent of an aircraft, most 
commonly used on gliders. The ailerons are set to go up a modest amount, say 20%, while 

the flaps go down a large amount. This combination creates a lot of drag, and is very 
effective for braking and therefore ideal for controlling the landing approach.

For this example it will be assumed that a Butterfly mix is to be added to a glider which 

already has Flap channels created by the model creation wizard. Gliders typically use the 
throttle stick for braking. We will configure the mix so that no butterfly is added with the 

throttle stick up, and butterfly progressively increases as the stick is moved down. 

Compensation is also needed on the elevator to avoid the glider ballooning up when crow is 
applied. We will use a curve because the response is non-linear.

Step 1. Disable the default Flaps mix

We will not be using the default Flaps mix, so if not already disabled, we will disable it by

setting the Active Condition in the Flaps mix to ‘---’.

Step 2. Create the Butterfly mix.

Tap on any mixer line and select ‘Add Mix’ from the dialog. Select Butterfly from the 
Mixer library, then add it at the desired point in the mixer list, normally after the Flaps 

mix.
