and is usually used to make steep descents or to limit increases in airspeed in dives. Two separate
BUTTERFLY
settings are
available. (

Adjustability:
• Activation: Proportional by moving the THROTTLE STICK.
• Switch: Mix SWITCH is selectable.
A
to
H
: SWITCH A to H
NULL
: always on.
Also LOGIC SW (Lsw1 to 3) may be assigned. Set up
LOGIC SW
: See p. 38.
• Inversely proportional to THROTTLE STICK: provides a proportional increase in amount of airbrake action as
THROTTLE STICK is lowered (when SWITCH A (assignable) is in the down position). Includes selectable stick
position where airbrake begins. 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.
• Elevator settings: (adjustable in the
B.FLY-ELE
)
B.FLY-ELE
links elevator with the
BUTTERFLY
function. Elevator rate is adjustable
in a 3 point curve.
Point 1:
PRESET
point. (Fixed)
Point 2:
MID
point. Position and rate are adjustable.
Point 3:
END
point. Position and rate are adjustable.
• Delayed reaction: You can suppress sudden changes in your model's attitude when
BUTTERFLY
is activated by setting the
delay (

• Twin aileron servos: If
AIL-DIFF
function is inhibited, then
AIL1
and
AIL2
settings will have no effect.
• If
AIL-DIFF
is active, then CH1 and CH7 may be independently adjusted.
• Normally both ailerons are raised equally in
BUTTERFLY
, and the elevator motion is set to maintain trim when the ailerons
rise. Dif
ferent 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
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
encourages tip stalling. If you are using this for aerobatic performance and not "sudden stops", consider raising the
