GV-1: part number/name for Futaba’s electronic governor. See Gyros and Governors and GOVERNOR for details.
Gyro, gyroscope: equipment that senses change in direction and provides input to compensate for that change. For
description of aircraft use, see p. 64. For description of types, and helicopter use, see GYRO SENS.
GYRO SENS (HELI): gyro sensitivity programming designed to ease the setup and use of gyroscopes on model helicopters.

Heading-hold gyro: gyro that specifically measures the unwanted deflection angle and compensates until a corresponding angle
has been returned. See Gyros and Governors.
HELI: model type, rotary wing. See MODEL TYPE.
Helicopter radio: transmitter that includes helicopter-friendly switch and control layout and sufficient programming to
at least support a 5-channel helicopter. The 9CA and 9CH radios both contain all needed programming. The 9CH has a
more heli-friendly layout (through switch positioning and no ratchet on throttle for easier hovering)
High band: 72MHz equipment on a channel from 36 to 60. Receiver channel may be changed to any channel within the
high band without needing retuning. Transmitter must not be changed except by certified technician. . . . . . . . . . . . . .8
High Rate: See D/R,EXP.
Hover: to maintain a stationary position relative to a point on the ground.
HOVERING PITCH: see Hovering setups.
HOVERING THROTTLE: see Hovering setups.
Hovering setups: in-flight adjustments to pitch and throttle curves around center T
HROTTLE STICK position (the ideal
hovering point). . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .88
Idle management: varying settings and control of the model’s idle. Ex: using IDLE-DOWN to lower engine’s idle point for
landings and certain maneuvers; using THR-CUT function to safely and accurately shut the engine off as needed without
requiring constant adjustment of throttle trims. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .33
IDLE-DOWN: offset mix that slows the engine’s idle point (decreasing the amount of travel of the throttle servo when at
low T
HROTTLE STICK POSITION
). Typically used to keep the model sitting still on the runway prior to take off, for slow
aerobatic maneuvers such as spins, and for landings. See Idle management. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .33
IDLE-UP: separate condition created to allow inverted and other types of flight with a helicopter not easily achieved in
the normal condition. Note: the idle-ups are activated by activating their throttle curves. Also note that OFFSET is
available to create separate trims within each condition. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .85
In-flight needle control: see THROTTLE-NEEDLE.
INH: makes a feature inactive/unable to be used. When a function is inhibited, it cannot be used even if the assigned
switch is ON. Turns off functionality without losing any settings. Only visible in specific features.
Inhibit: see INH.

Inverted: to fly a model upside-down.
Inverted flight control programming: not available in the 9C. Most modelers no longer use this “crutch” to fly inverted,
instead learning to recognize the model’s behaviors when inverted and compensate appropriately.
Kill switch: (1) throttle cut switch to close carburetor (see THR-CUT, p. 33). (2) gasoline ignition engine kill switch
which removes spark to the plugs to stop the engine. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .64
