INTRODUCTION TO THE 4EX SYSTEM

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 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 four different models. The new, adjustable-length control sticks provide an

improved feel. External switches operate trainer cord or

“

buddy-box

”

capabilities. Programming features include servo reversing

and E.P.A on all channels, exponentials. Additionally, any one of three, factory-set, preprogrammed

“

wing-type

”

mixers including

V-tail, elevon mixing may be selected.

Transmitter controls

The diagram and explanations briefly describe the functions of the Futaba T4EX 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 14).

DESCRIPTIONS:

Neck strap hook -

Mounting point for optional neck strap.

Aileron/elevator control stick -

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

Trim levers (all) -

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

NOTE:

Changing the trims affect the overall settings. When trim usage is extreme, recheck your installation for

maximum travel.
