Thermal hunting setup: using specific programming setups to have the model respond noticeably to the lift of a
thermal. Not a preprogrammed mix. See Programmable mix.
THR-DELAY: (ACRO) throttle delay, slows engine servo response to imitate the spool-up action of a turbine engine. May also
be used creatively to create a delayed servo on a different function (see www.futaba-rc.com\faq\faq-9c.html.) . . . . . . . .59
THR-REV: reverses the throttle trim function to the top of the THROTTLE STICK. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .31
THROTTLE-NEEDLE: (ACRO / HELI) curve mix that adjusts a second servo, controlling the engine’s mixture, to get optimum
RPM and performance from the engine at all settings. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .58
Throttle-to-rudder mix: used to compensate with rudder when throttle is applied on take off. Not a preprogrammed
mix. See Programmable mix. This is the default setting of a mix in ACRO and GLID.
THROTTLE CURVE: (HELI) adjusts how the servo responds to the T
HROTTLE STICK position along a 5 point curve. Separate
curves available for each idle-up and normal. For simplicity, normal curve may be edited from BASIC menu. All curves
may be edited together in the ADVANCE menu. Activating an idle-up’s throttle curve is what activates that idle-up. .86,89
Throttle cut or throttle kill: THR-CUT. (ACRO / HELI) Offset mix which closes the throttle servo to a set position when the
assigned switch is moved to shut the engine off without having to fiddle with trim settings. . . . . . . . . . . . . . . . . . . . .33
THROTTLE HOLD: (HELI) makes the throttle servo non-responsive to T
HROTTLE STICK position, and moves the throttle to idle.
Used to practice autorotations. NOTE: THR-HOLD must be activated, then the default pitch curve adjusted properly. . . . . . . . .88
Throttle trim adjustment: see ATL to change throttle trim from “idle only” to full trim control like all other channels. See
THR-REV to reverse T
HROTTLE STICK completely, including moving trim to the top of the THROTTLE STICK. See also Idle
management for details on idle down and throttle cut functions.
TIMER: adjust the timer functions, used to keep track of flight time on a tank of fuel, etc. The “trigger” to turn timers
on/off may be programmed. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .38
TP-FM: single-frequency module. See Module.
TRAINER: software that allows 2 radios to be connected via trainer cord, giving student control of all or some of the
channels of the aircraft at the flip of a switch. FUNC trainer mode allows student to use mixing in the master transmitter,
for example dual rates, exponential, fly a 5-channel helicopter with a 4-channel buddy box, etc. . . . . . . . . . . . . . . . .40
Trainer box: stripped-down radio system which does not have the ability to transmit, is used only as a student’s radio
when instructing while using a trainer cord and the trainer programming.
Trainer cord: cord used to connect two compatible radios to use for flight instruction. See Accessories.
TRIM menu: adjusts rate at which the trim responds to movement of the trim sliders. Also has a reset function to reset
the model’s electronic trims to zero. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .41
TRIM OFFSET: (HELI) sets an offset or adjustment of trim when switching between conditions. See OFFSET.
TRIM option in mixes: ability to adjust the slave servo’s center when the master servo’s center is adjusted using the trim
sliders (for example when using two separate flap servos). See Programmable mix. . . . . . . . . . . . . . . . . . . . . . . . . . .54
Triple rate: 3rd control travel setting available in flight. See D/R,EXP.
Twin aileron servos: use of 2 or more servos on separate channels to control aileron action. Includes flaperon, aileron
differential, and elevon. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .44

VR(A-E): variable rate controls. Knobs and sliders on the radio. See switch assignment chart for default assignments.
