ATL: Adjustable Travel Limited. Standard type of trim used for throttle, where the trim is effective only in the idle portion of the

OSITION
. Normal trims affect the entire travel of the servo (ex: elevator trims), but ATL trims only the low end
of the throttle movement, allowing throttle idle adjustments that don’t over-drive the servo at full throttle. . . . . . . . . . . . . . . .31
ATV: Older, less clear terminology for end point adjustment. See END POINT.
Autorotation: The ability of a helicopter to land safely without engine power, using the stored energy in the blade’s
rotation to produce lift for flaring.
AUX-CH: Auxiliary channel setup. Used to assign which KNOBS/SWITCHES/SLIDERS control channels 5-9. Includes CH9 servo
reverse. Also allows assignment of a channel to mixing only (assigned as NULL), with no primary control. . . . . . . . . . . . . . . .39
Backup battery: battery used to protect data storage in case of removal of master transmitter battery. In most Futaba
radios, including the 9C, EEPROM data storage is used, so no backup battery is used or needed.
BACKUP ERROR: transmitter’s hard-coded memory has been lost. Send for service immediately. . . . . . . . . . . . . . . . . .19
Base-Loaded antenna: also called Whip antenna. Aftermarket equipment not approved by Futaba.

Battery FailSafe: determines how the receiver indicates an airborne pack low-battery warning. Defaults: 56% throttle,
requires throttle to idle to override. To adjust the warning point, set a THROTTLE

BEEP: tone emitted by transmitter to signify a variety of situations. See Error messages.
Binding: friction in a joint exceeding the movement of the linkage. Sticking or inability to continue movement. The servo
continues to attempt to move the surface beyond its power/capabilities, rapidly draining battery power as it continues to struggle.
Brake flap mixing: (GLID) Three mixes: brake flap- to-elevator, to-aileron and to-speed flaps. 1) compensate for
unwanted reaction to lowering the brake flap, 2) increase brake flap area by including the flaperons, and 3) add lift to
increase maneuverability. Not a preprogrammed mix. See Programmable mix.
Buddy Box: see Trainer box.
BUTTERFLY: (GLID) [also called crow, AIRBRAKE (ACRO)]. Activates up flaperons and down flaps for gliding speed control
without spoilers or airbrakes. Note: More adjustable programming is available in ACRO, AIRBRAKE. . . . . . . . . . . . . . .55

CCPM: Cyclic (pitch and roll) Collective Pitch Mixing. Multiple servos work in unison on the helicopter’s head to create one
or more of the control functions. Ex: 3 servos set at 120 degrees operate the entire head. The 2 forward servos work together to
rotate both the blade’s pitch and the roll cyclic (aileron) in a SR3 head type. See MODEL TYPE, HELI.
CH5&6: setting in AIL-2 that allows the second aileron servo to be in channel 5. See Twin aileron servos.
CH6 or 7: default setting in AIL-2. Second aileron servo is in channel 6 or 7 depending on function used. See Twin aileron servos.

Channel delay: see THROTTLE DELAY (ACRO) and DELAY (HELI).
Charge: to increase the electrical energy, measured as voltage, available in a battery pack. See Battery care and charging.
Condition: (HELI) separate flight setup that has significant adjustability separate from the basic model setup. See IDLE-
UP 1, 2, 3 and THROTTLE HOLD.
