4.3.8 BUTTERFLY (crow) mixing
BUTTERFLY simultaneously moves the flaps, twin ailerons and elevator, and is usually used to make steep
descents or to limit increases in airspeed in dives. Separate two BUTTERFLY settings are available. (CRI1/CRI2)
ADJUSTABILITY:
•
Activation: Get proportional by moving the THROTTLE STICK.
•
Switch: Mix SWITCH is selectable. A to H: SWITCH A to H. Also LOGIC SW (Lsw1 to 3) may be assigned.
NULL: always on.
•
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 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:
this changes the throttle stick direction for all models.
INSTRUCTIONS:
•
Elevator settings: (Adjustable in the B.FLY-ELE)
B.FLY-ELE works linking with 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 (DELAY) item, to slow down the elevator response, allowing the flaps/ailerons/elevator to all
reach their desired end point together. A setting of 100% slows the servo to take approximately one second to
travel the prescribed distance.
•
Channels controlled: Twin ailerons, flap and spoiler may be set independently in BUTTERFLY, including set to
0 to have no effect.
•
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. 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 BUTTERFLY. Along with creating an enormous
amount of drag (desirable 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 ailerons and dropping the flaps in stead as shown in the diagram above.
