AIRBRAKE
BUTTERFLY
(crow) mixing
(

):
Like
FLAPERON
and
AILEVATOR
,
AIRBRAKE
is one function that is really made up of a series of pre-programmed mixes all
done for you within the radio.

•
Linear
(
Inversely proportional to
THROTTLE STICK
): provides a proportional increase in amount of
AIRBRAKE
action as
THROTTLE STICK
is lowered and assigned switch is on. Provides gradually more
AIRBRAKE
as you slow
the engine. Includes selectable stick position where
AIRBRAKE
begins, gradually increasing to the same setting as the
THROTTLE STICK
is lowered. If you would like to have the airbrake be directly proportional to throttle stick, you will
need to reverse the
THR-REV
function. Note that this changes the throttle stick direction for all models. See page 38 for
instructions.
•
Offset
: Provides
AIRBRAKE
response immediately upon switch movement, going to a pre-set travel on each active channel

• During Airbrake operation, the elevator travel is displayed on the elevator trim display in the Startup screen.
•
Delayed reaction
: You can suppress sudden changes in your model's attitude when
AIRBRAKE
BUTTERFLY
is activated
by setting the delay (

• Twin aileron servos: If

functions are inhibited, then
AIL1
and

settings will have no
effect.
• If
FLAPERON
is active, the travel of the ailerons can be independently adjusted for the servos plugged into CH1 and

• If
AIL-DIFF
is active, then CH1 and CH7 may be independently adjusted.
• Normally both ailerons are raised equally in
AIRBRAKE
, and the elevator motion is set to maintain trim when
the ailerons rise. Different amounts may be set for each aileron to correct for torque reactions and other unique
characteristics of the model.
Be sure you understand what dropping ailerons will do when in
AIRBRAKE
BUTTERFLY
. Along with creating an
enormous amount of drag (desireble for spot landings), this also creates "wash-in", a higher angle of attack where
the ailerons are, and cncourages tip stalling. If you are using this for aerobatic performance and not "sudden stops",
