AIRBRAKE BUTTERFLY (crow) mixing (ACROGLID):
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. 80 for details) simultaneously

Adjustability:
• Activation: Proportional by moving the THROTTLE STICK

• Switch: Mix SWITCH is selectable.
*Also LOGIC SW (Lsw1 to 3) may be assigned. Set up LOGIC SW: See p. 38.
• 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

prescribed distance. (GLID: B.FLY-ELEV function)

• Twin aileron servos: If FLAPERON, ELEVON and AIL-DIFF functions are inhibited, then AIL1 and AIL2 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",
