Butterfly

Glider Braking System Adjustment
This submenu option is not available for certain model
types and configurations.
Use this menu to set a special breaking flap arrange-
ment: the crow or butterfly position. In this braking
position, both ailerons are moved slightly upward,
and the flaps move downward as far as possible. By
means of an additional mixer (the "elevator curve"
mixer described below), the elevator is trimmed so
that the flight speed does not change significantly in
comparison to the normal flight position. Otherwise,
there is a danger that the model will slow down too
much and, after the brake system is retracted (for
example to lengthen a landing approach that is too
short), will crash or fall.
This interaction of the flaps, aileron and elevator con-
trol the gliding angle when approaching a landing.
(The butterfly flap position is frequently used in sports
models instead of brake flaps or spoilers).
To adjust these settings, from the main display press
the FUNCTION menu gear icon (blue "F") to bring up
the FUNCTION submenu screen:

Phase-Dependent Settings
This submenu allows for different phase-specific val-
ues to be programmed. Phase names are displayed
in green in the upper left side of the screen next to
the BACK button. Standard default naming for the
phases are usually displayed as NORMAL/PHASE
1. (Additional phases will be named numerically, e.g.
Phase 2, Phase 3, etc.) To define multiple phases,
refer to the FUNCTION submenu Phase section (page
120). Each new phase will need to be assigned to a
different switch. To change the phases, activate the
corresponding switch(es).
Programming
The butterfly mixers described below are actuated by
the throttle/brake control stick, assigned by default to
the CH1 input (or alternately by any other transmitter
control element that is assigned to the CH1 input of
the BASE submenu CTL Set).
In most cases, the selection is limited to preset con-
trol, and the airbrake is operated using the non-cen-
tralizing CH1 control stick:
BACK PHASE 1 CTL Set
CH 1. ST 1
CH 2. ST 2 +100% +100%
CH 3. ST 3 +100% +100%
CH 4. ST 4 +100% +100%
CTL OFFSET – Travel+
The use of other control elements offers the possibil-
ity of being able to control the airbrakes alternatively
through another accessory function control. This is
useful if the CH1 control stick is going to be used for
other functions.
