Elevator-to-pitch mix: (HELI) used to adjust pitch to counter the loss of angle of attack when elevator input is given. Not
a preprogrammed mix. See Programmable mix. This is the default setting of one mix in HELI.
ELEVON: flying wing configuration with 2 servos working together to create both aileron and elevator action. See Twin
elevator servos. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .4

Elevons: two surfaces, one on each wing, which work as both ailerons and elevators. See ELEVON.
E ND B UTTON : control button used during programming to return to previous menu or close menu altogether.
END POINT: often abbreviated EPA. Adjusts the total travel in each direction of proportional servos regardless of their control
assignment. Ex: adjustment to AIL channel will adjust only the servo plugged into channel 1 even if being used as one of two
flaperons or elevons. Note: End point is not an absolute; mixing can still drive the servo farther than this setting. . . . . . . . . . .32
Engine cut: see THR-CUT.

Error messages: warnings/cautions provided by the radio when potential problems may exist. . . . . . . . . . . . . . . . . . .19
Exponential (D/R,EXP): adjustment to the relationship of S TICK M OVEMENT to servo movement, typically used to soften
overly sensitive models around center. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .35
FailSafe (F/S): sets servo positions when interference is encountered or signal is lost. Available only in PCM
transmission mode. Also includes Battery FailSafe settings. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .43
FLAP1/2/3/4: designation for the individual servos that are being commanded by the flap commands. Ex: when acting as
flaperons, the two aileron servos are ailerons 1 and 2 and also flaps 1 and 2 (unless you set their values to 0, then they move
only as aileron no matter what flap commands are given). See Twin aileron servos and Twin elevator servos.
Flap-to-aileron mix: (ACRO / GLID) used to create full span flap reaction in flight. Not a preprogrammed mix. See
Programmable mix. This is the default setup of one mix in GLID.
Flap-to-elevator mix: (ACRO / GLID) used to counteract unwanted changes in pitch when flaps are deployed. Not a
preprogrammed mix. See Programmable mix. This is the default setup of one mix in ACRO and GLID.
FLAPERON: one servo on each aileron, plugged into channels 1 and 6, which operate both as ailerons and as flaps. See
Twin aileron servos. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .44
FLAP-TRIM: Adjustment of central position of flaperons, default assigned to C HANNEL 6 K NOB . May also be used as
primary or only control of flaperons acting as flaps, or other mixes may be set up. See Twin aileron servos. . . . . . . .46

Frequency band: In the entire spectrum, transmissions are designated in terms of “frequency bands” which exhibit similar
properties. In the US, specific frequencies within the 72MHz band are regulated by the FCC to be used solely for remote
control aircraft. 50MHz band is available for model use by those holding a HAM amateur radio operator’s license. 75MHz
is solely for remote control ground models. 27MHz is legal for air or ground use. To change bands on the 9C, simply
purchase and install a module on the proper band. Receiver band MUST be changed by a service center. . . . . . . . . . . . .17
Fuel mixture control: (ACRO / HELI) see THROTTLE-NEEDLE.
FUNC: function mode of TRAINER, allows student radio to use the computer programming for that channel in the master radio.
Ex: allows a student with a 4-channel transmitter to fly an 8-servo aerobatic plane or a 5-servo helicopter. See TRAINER.
Gain: the responsiveness or amount of control given the gyro. On a high gain, the gyro is very active and overrides
nearly all other actions. Too high a gain may result in “wagging” at the surface as the gyro over-corrects repeatedly in
each direction. See GYRO SENS.
Gear doors: covers for retractable landing gear, may be operated separately from landing gear on some models. . . . .66

Governor: electronic device that reads the speed at which the head is spinning, and adjusts the throttle servo to maintain
the desired speed.
