Futaba T6EXA-72 Users Manual

INTRODUCTION TTO TTHE 66EXA SSYSTEM

IMPORTANT!:

Always turn on the transmitter first, then the receiver. When turning off the system, always turn off the receiver
first. The object is never to have the receiver on by itself. Otherwise, the servos or control surfaces could be damaged, or in the
case of electric-powered models, the motor may unexpectedly turn on causing severe injury.

IMPORTANT!:

Never collapse the transmitter antenna by pushing down from the top. If one of the segments becomes momentarily

stuck you may damage the antenna. Instead, collapse the antenna from the bottom, drawing in one segment at a time.

Transmitter
The T6EXA FM 6-channel transmitter may be used with any Futaba, narrow band, FM receiver. The liquid-crystal display (LCD)
on the face of the compact, ergonomically-designed case is easy to read and allows rapid data input. The system also holds
independent memories for six different models. The new, adjustable-length control sticks provide an improved feel. External
switches operate dual rates (D/R), landing gear, and trainer cord or “buddy-box” capabilities. Programming features include
servo reversing and E.P.A on all channels, dual rates, exponentials and programmable mixing. Additionally, any one of four,
factory-set, preprogrammed “wing-type” mixers including flaperon, V-tail, elevon or flaperon + V-tail mixing may be selected.

Transmitter ccontrols
The diagram and explanations briefly describe the functions of the Futaba T6EXA transmitter. Full instructions on how to
operate the controls are provided beginning on page 9.
NOTE:

The diagram shows a Mode 2 system as supplied. (More on flight modes on page 18).

DESCRIPTIONS:

Aileron aand EElevator ddual rrate sswitch
Use this switch to “flip” between two aileron and elevator control throw settings. The throws can be set up however you prefer,
but generally, when the switch is “up” the throws are greater (“high rate”) and when the switch is “down” the throws are less
(“low rate”). This switch also flips between exponential rates (if used).
Flap ccontrol ddial/Channel 66

- This dial operates the servo connected to channel 6 in the receiver—if your model has flaps this
is the control used to operate them.
Neck sstrap hhook -

Mounting point for optional neck strap.

Aileron/elevator ccontrol sstick

- Operates the servos connected to channel 1 (aileron) and channel 2 (elevator) in the receiver.

Trim llevers ((all)

- Used to shift the neutral or center position of each servo as labeled in the diagram.

NOTE:

The throttle trim lever is intended for fine tuning the throttle servo when the engine is at idle. Throttle trim does not
affect the throttle servo when the throttle control stick is all the way up (so idle r.p.m. can be adjusted without affecting
throttle settings through the rest of the stick movement).

Throttle/rudder ccontrol sstick

- Operates the servos connected to channel 3 (throttle) and channel 4 (rudder) in the receiver.

Trainer/throttle-ccut sswitch

- Operates both the trainer and throttle-cut functions. To operate as a trainer switch the transmitter
must be connected to another transmitter via. a trainer cord (available separately). To use the throttle-cut function, lower the
throttle stick all the way, then rapidly depress the switch twice to fully close the carburetor and shut off the engine.
Retractable llanding ggear sswitch/Channel 55

– Switch operates the servo connected to channel 5 in the receiver—if your model
has retractable landing gear this is the control used to extend and retract the gear.
Antenna

– Radiates signals to the receiver. Never fly a model without fully extending the antenna or you may create
interference to other modelers and decrease operational signal range of the transmitter. The antenna may be removed and
replaced with another in case it is inadvertently broken.

RADIO IINSTALLATION

Follow these guidelines to properly mount the servos, receiver and battery.

•

Make certain the

alignment ttab

on the battery, switch and servo connectors is oriented correctly and “keys” into the
corresponding notch in the receiver or connectors before plugging them in. When unplugging connectors, never pull on the
wires. Always pull on the plastic connector instead.

•

If any servo wires are not long enough to reach the receiver, servo extension wires (available separately) may be used.

•

Always mount the servos with the supplied

rubber ggrommets

. Do not over tighten the
screws. No part of the servo casing should contact the mounting rails, servo tray or any
other part of the airplane structure. Otherwise, vibration will be transmitted to the servo
causing premature wear and/or servo failure.

•

Note the small numbers (1, 2, 3, 4) molded into each arm on the Futaba 4-arm servo
arms. The numbers indicate how many degrees each arm is “off” from 90 degrees to
correct for minute manufacturing deviations from servo to servo.

•

To center the servos, connect them to the receiver and turn
on the transmitter and receiver. Center the trims on the
transmitter, then find the arm that will be perpendicular to
the pushrod when placed on the servo.
