3.3.6 Air Break (ACRO/ GLID)

ACRO GLID
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. AIRBRAKE (often called "crow" or BUTTERFLY -
see GLID, p. 62 for details) simultaneously moves the flap (if installed), twin ailerons (if installed) and elevator,
and is usually used to make steep descents or to limit increases in airspeed in dives.
This function is often used even on models without flaps as an easy way to use the FLAPERON and
FLAP-ELEVATOR mixing together.
Adjustability:
• Activation: be proportional by moving the THROTTLE STICK, or set positions by flipping the assigned
switch.
• Switch: Mix SWITCH is selectable.
• Also LOGIC SW (Lsw1 to 3) may be assigned.
• 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. It 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.
• Offset: Provide AIRBRAKE response immediately upon switch movement, going to a pre-set travel on each
active channel without any means of in-flight adjustment.
• 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 (delay-ELEV) 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. (GLID: B.FLY-ELEV
function)
• Adjustable in flight (ACRO): Using the aileron (when AILE-DIFF or FLAPERON is activated) and elevator
trim lever in flight can be set to adjust the aileron and elevator settings in your airbrake rather than adjusting
the model's actual aileron and elevator trim. This allows easy adjustment for any ballooning while in flight.
When the airbrake switch is moved to off the trim is again adjusting the normal elevator trim.
• Channels controlled: Elevator, twin ailerons and flap may be set independently in AIRBRAKE, including set
to 0 to have no effect.
• If FLAPERON is active, the travel of the ailerons can be independently adjusted for the servos plugged into
CH1 and CH6. The flap choice has no effect on the FLAPERON.
• 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
