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 fl y 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. ............ 74
GLID
: model type, glider. ...................................................................................................................................................... 75
Governor: electronic device that reads the speed at which the head is spinning, and adjusts the throttle servo to maintain
the desired speed.
GOVERNOR
: (
HELI
) programming which eases the setup of the GV-1 governor. ................................................................. 106
GV-1: part number/name for Futabais 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. 66. For description of types, and helicopter use, see
GYRO SENS
.
GYRO SENS
(
ACRO
/
HELI
): gyro sensitivity programming designed to ease the setup and use of gyroscopes on model
airplanes and helicopters. Manual pages include extensive descriptions of gyro types. ............................................. 73, 106
Gyros and Governors ......................................................................................................................................................... 106
Heading-hold gyro: gyro that specifi cally measures the unwanted defl ection 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 suffi cient programming to at
least support a 5-channel helicopter. The 9CA super and 9CH super radios both contain all needed programming. The 9CH
super has a more heli-friendly layout (through switch positioning and no ratchet on throttle for easier hovering)
HI/LO-PIT
(
HELI
): may be used to adjust pitch curves high and low side in fl ight. ............................................................. 105
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 certifi ed 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-fl ight adjustments to pitch and throttle curves around center THROTTLE STICK position (the ideal
hovering point). .................................................................................................................................................................. 104
Idle management: varying settings and control of the modelis 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. ................................................................................................................... 40
IDLE-DOWN
:: of
fset mix that slows the engineis idle point (decreasing the amount of travel of the throttle servo when at low
THROTTLE 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. ..................................................................... 40
IDLE-UP
: separate condition created to allow inverted and other types of fl ight 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. ...................................................................................................................... 101
