Congratulations! You now own a Hitec
R
Optic , an extremely
versatile
radio control system that may be effectively used by
both
beginning and master pilots. The transmitter may be
programmed
for aircraft/gliders or helicopters, all with special
mixing
functions, so it can accommodate many model
configurations.
You can store programming for eight different
models
in this powerful system! The transmitter will remember
all
of your settings for each of your different models forever -
no
backup battery is ever needed. With programmable shift, it
can
be used with all PPM/FM receiver models, even those
from
other brands! The system pushbuttons allow rapid data
input
into the easy-to-read LCD display. With its electronic
digital
trims, you'll never lose your trim positions again,
because
they stay at the same place you left them for every
model
stored in memory! You can select the on-off switches
for
many functions, and you can even assign the throttle to an
on-off
switch, great for electrics! Standard programming
features
include servo reversing for all channels, subtrims, end
point
adjust on all channels, dual rates (with choice of switch),
and exponential. Pre-programmed functions and programmable
mixers
allow you to use the system for any type of model you
can
imagine. For those learning to fly, the transmitter has
"buddy-box" capability, so that you may connect a second
Hitec
transmitter with an optional trainer cord part #58310 for
training
by an instructor pilot.
There are two aircraft menu's to choose from:
Aircraft/Glider preprogrammed mixing features include
flaperon
(dual aileron servos), flap trim, camber control,
landing
mixing, aileron differential, ailevator (dual elevator
servos), V-tail, elevon (for flying-wing models), landing settings,
throttle-cut,
throttle control select, aileron rudder mixing,
elevator
flap mixing, and crow mixing. Two programmable
mixers
are also provided for making your own custom functions.
The
second aileron may be set to plug into channel 5, so you
can
use the system with ultralight five-channel receivers
without any problems!
Helicopter features include five-point pitch and throttle curves,
high
and low revolution mixing, throttle cut, throttle hold, gyro
settings,
and rudder throttle mixing. You may select a
conventional
swashplate, or if you have a more complex
chopper,
mixing is provided for the 120 type of three-servo
swashplates.
Two programmable mixers are also provided for
making
your own custom functions or for custom
compensations.
Of course, the Optic helicopter menus have
the
four helicopter flight mode settings found in other radios
costing
hundreds of dollars more.

To ensure your own safety and the safety of others, please
observe
the following precautions:
Charge the Batteries!
Be sure to recharge the batteries before each flying session.
A
battery low in charge will soon die, causing loss of control
and
a crash. Plug in the charger that comes in this system
and
hook up the transmitter and airborne batteries the day
before
a planned flying session. Be sure the charger is not
turned
off by the room's light on-off switch!
When you begin your flying session, reset the transmitter's
timer
to keep track of how long the system's been used, and
monitor
the transmitter's voltage display. Quit flying when your
transmitter
battery level reaches 9.4 volts.
Be careful when you use a field charger on your batteries.
A
fast-charger may overcharge the batteries, causing
overheating
and a premature failure. Never charge your
transmitter
or receiver battery at a rate higher than 2 amps.
Flying field
We recommend that you fly at a recognized model airplane
flying
field. You can find model clubs and fields by asking the
nearest
hobby dealer, or contacting the Academy of Model
A
eronautics. Always pay particular attention to the flying
field's rules, as well as the presence and location of spectators,
the
wind direction, and any obstacles on the field. Be very
careful
flying in areas near power lines, tall buildings, or
communication
facilities as there may be radio interference in
their
vicinity. If you must fly at a site that is not a club field, be
sure
there are no other modelers flying within a two-mile range,
or
you may lose control of your aircraft.
motor may unexpectedly turn on and cause a severe injury.
Before
starting the engine, fully retract the transmitter antenna,
power
up the transmitter and receiver, and check to be sure
that
the servos follow the movement of the sticks. If a servo
operates
abnormally, don't attempt to fly until you determine
the
cause of the problem. We recommend that you range-
check
your system before each flying session. Have an
observer
verify that the system works with the transmitter about
30 paces away with the transmitter antenna collapsed. Finally
,
before starting the engine, be sure to check that the transmitte
r
model memory is correct for the chosen model.
While you're getting ready to fly, if you place your transmitter
on
the ground, be sure that the wind won't tip it over. If it is
knocked
over, the throttle stick may accidentally get moved
causing
the engine to race unexpectedly, causing damage or
injury
to anyone nearby.
Before taxiing, be sure to extend the transmitter antenna to its
full
length. A collapsed antenna will reduce your flying range
and
may cause a loss of control. It is a good idea to avoid
pointing
the transmitter antenna directly at the model at all
times,
since the signal is weakest in that direction.
Finally, don't fly in the rain! Water or moisture may enter the
transmitter
through the antenna or stick openings and cause
erratic
operation or loss of control. If you must fly in wet
weathe
r
during a contest, be sure to protect your transmitter
with
a plastic bag or waterproof barrier.
Once you arrive at the flying field...
Before flying, be sure that the frequency you intend to fly with is
not
in use, and secure any frequency control device (pin, tag,
etc.)
for that frequency before turning on your transmitter.
Never
believe that it's possible to fly two or more models on the
same
frequency at the same time. Even though there are
different
types of modulation (AM, PPM or FM, and PCM), only
one
model may be flown on a single frequency.
When you are ready to fly your model, position the throttle stick
or
switch to its low speed position, or do whatever is necessary
to
command your motor NOT to run. Then, you may turn on
the
transmitter power followed by the receiver power. Use the
LOCK
function to prevent accidental throttle commands. When
you
have finished flying, begin by turning off the receiver power,
then
turn off the transmitter power. If you do not follow these
procedures,
you may damage your servos or control surfaces,
flood
your motor, or in the case of electric-powered models, the

It is very important to display your transmitters channel number
at
all times. To install your frequency flag device on your
transmitters
antenna, slide the appropriate paper numbers into
the
slots and slip the device onto the transmitters antenna.
Radio Installation Notes
While you are installing the battery, receiver, and servos into
your
model's fuselage, please pay attention to the following
guidelines:
Notes on Servos
Mounting
When you mount each servo, use the supplied rubber
grommets
and insert an eyelet up through the bottom. Be sure
not
to over tighten the screws. If any portion of the servo case
directly
contacts the fuselage or the servo rails, the rubber
grommets
will not be able to attenuate vibration, which can
lead
to mechanical wear and servo failure.
Switch Harness Installation
When you are ready to install the switch harness, remove the
switch
cover and use it as a template to cut screw holes and a
rectangular
hole slightly larger than the full stroke of the switch.
Choose
a switch location on the opposite side of the fuselage
from
the engine exhaust, and choose a location where it can't
be
inadvertently turned on or off during handling or storage.
Install
the switch so that it moves without restriction and "snaps"
from
ON to OFF and vice versa.
Receiver Notes
DO NOT cut or coil the receiver antenna wire. It is normal for
the
receiver antenna to be longer than the fuselage. DO NOT
cut
it or fold it back on itself - cutting or folding changes the
electrical
length of the antenna and may reduce range.
Secure the antenna to the top of the vertical fin or the tail boom,
and
let the excess length trail behind the aircraft (be sure it
cannot
tangle with the tail rotor on a helicopter).
Servo Throw
Once you have installed the servos, operate each one over its
full
travel and check that the pushrod and output arms do not
bind
or collide with each other, even at extreme trim settings.
Check
to see that each control linkage does not require undue
force
to move (if you hear a servo buzzing when there is no
transmitter
control motion, most likely there is too much friction
in
the control or pushrod). Even though the servo will tolerate
loads
like this, they will drain the battery pack much more rapidly.
You may run the antenna inside of a non-metallic housing
within
the fuselage (a plastic outer pushrod housing works well
for
this), but range may suffer if the antenna is located near
metal
pushrods or cables. Be sure to perform a range check
before
flying. With the antenna collapsed, you should be able
to
walk 20 - 30 paces from the model without losing control or
seeing
"jitter" in the servos. The range check should be done
with
the motor running and the model should be securely
restrained
in case of loss of control.

Radio Installation Notes
Connectors
Be sure the alignment of a servo or battery connector is correct
before
inserting it into the receiver. To remove a connector
from
the receiver, try to pull on the connector's plastic housing
rather
than pulling on the wires. Pulling the wires can ruin the
connector
pins and break wires.
Using The Aileron Extension
If any of your servos are located too far away to plug directly
into
the receiver (like the aileron servo), or you need to unplug
the
servo each time you disassemble the model, use a servo
extension
cord to extend the length of the servo lead.
A
dditional Hitec extension cords of varying lengths are
available
from your hobby dealer.
V
ibration and Waterproofing
The receiver contains precision electronic parts. Be sure to
avoid
vibration, shock, and temperature extremes. For
protection,
wrap the receiver in the provided "Flight Preserver"
foam
rubber, or use some other vibration-absorbing materials.
It's
also a good idea to waterproof the receiver by placing it in a
plastic
bag and securing the open end of the bag with a rubber
band
before wrapping it with foam. If you accidentally get
moisture
inside the receiver, you may experience intermittent
operation
or a crash.

Batteries
1. Connect the transmitter charging cord to the transmitter's
charging
socket (on the rear of the case, left side).
2. Connect the receiver battery to the receiver connector
on
the charging cord.
3. Plug the charger into a wall socket.
4. The charger's LEDs should light, indicating charging current
is
flowing. The batteries should be left on charge for about
15
hours. If either light does not turn on, verify that both
power
switches are OFF. Also be sure the wall switch
controlling
the room lights does not shut off the charger's
electrical
outlet when you leave the room.
- Try to charge the batteries with the charger supplied with your
system
exclusively. The use of a fast-charger may damage
the
batteries by overheating and dramatically reduce their
lifetime.
NOTE: If you need to remove or replace the transmitter battery, do not
p
ul
l
on its wires to remove it. Instead, gently pull on the connector's
p
lasti
c
housing where it plugs in to the transmitter. The battery must
be removed to charge it properly with a "peak" charger.
Operatin
g
With A Trainer Cor
d
A
n optional training cord is available from your dealer. The
cord
may be used to help a beginning pilot learn to fly easily by
allowing
a second transmitter, operated by an experienced
instructor,
to be connected to this system. The instructor may
override
the beginning pilot at any time to bring the model back
under
safe control. For training, the transmitter may be
connected
to another Hitec FM system using the Hitec cord
part
# 58310.
To use the trainer cord:
1. Set up both the student's and instructor's transmitters to
have
identical trim and control motions. If the instructor's
transmitter is on a different frequency than the student's,
use
the student's as the master transmitter and the other as
the
student's.
2. Collapse the student's antenna, and fully extend the
instructor's
antenna. If the student's transmitter has a
removable
RF module, remove it from the transmitter.
3. The Hitec cord is specifically marked at one end as the
"master" the other end as "student". Plug it accordingly into
each
transmitter, with power switched off. The trainer jack is
on
the back of the transmitter. Turn the connector until its
notches
line up and it fits without having to be forced.

4. Turn on the instructor's transmitter. DO NOT turn on the
student
transmitter power. Move the controls on the
instructor's
transmitter, and verify each control moves the
proper
direction. Now verify that the student's trims and
control
travels match the instructor's by using the trainer
switch
(the momentary Trainer switch on the top left of the
transmitter
case) and switching back and forth while leaving
the
control sticks and trims alone, then moving the control
sticks.
5. The instructor's transmitter has normal control over the
model
unless the trainer switch is pulled, passing control to
the
student's transmitter. If the student loses control, the
instructor
can quickly "take over" by releasing the trainer
switch
and controlling the model.

to
remove the rear case of the transmitter. Using a screwdriver,
remove
the six screws that hold the transmitter's rear cover into
position,
and put them in a safe place. Unscrew the antenna
and
set it aside. Now, place some padding under the front of
the
transmitter and set it face-down on the pad. Gently ease
off the transmitter's rear cover. Now you'll see the view shown.
Using
a small cross-point screwdriver, rotate the adjusting
screw
for each stick for the desired spring tension. The
tension increases when the adjusting screw is turned clockwise,
and
decreases for counterclockwise motion. When you are
satisfied
with the spring tensions, you may close the transmitter.

This screen appears at startup. The model memory number is
shown
by the small down-arrow. Battery voltage is shown in
the
bottom left, and operating time is on the lower right.
You can reset the operating time display by hitting the Clear
button (the one on the farthest right). Do this after each charge
to
keep track of your operating time on a single charge.
Pressing the Lock button locks the throttle servo and holds it
where
you last commanded it. This is a safety feature to be
used
when you are carrying the model and transmitter to
ensure
you don't accidentally give throttle. The LOCK indicator
shows
when the Lock switch has been engaged.

Pressing the Up button gives the Trim display (different
numbers
may appear depending on the model type). To see
where
the trim for a certain channel is, you have to move it!
Be sure to move it back to where it was. Note that the CH3 trim
only
moves downward, so if you need more engine RPM, set
up
idle with the trim at -25% so you can increase it if needed.
Warning Displays
The LOW BATTERY warning is displayed when the transmitter
battery
voltage drops below 9.3 volts, and a beeper sounds.
The
operating time is still shown on the right. If you reset this
each
time you charge the system, you will have a good idea of
how
long you can safely operate.
WHEN THE BEEPER SOUNDS, LAND YOUR MODEL AS
SOON AS POSSIBLE BEFORE LOSS OF CONTROL DUE
TO A DEAD TRANSMITTER BATTERY.
Pressing the Up button again gives the Model Name display.
If
you've named your model, it will appear here so you can be
sure you have recalled the correct memory. If you do not name
the
model, you'll have to remember which model memory it's
stored
within by the memory number.
The IDLE ON warning is displayed when the transmitter is
powered
up with the Idle switch on in the helicopter mode only.
You
can turn this off by moving the Flt. Mode (SW-4) switch
FORWARD.
For your safety, the transmitter will not broadcast
until
this alarm is ended
Pressing the Right button gives the Timer display, with a
stopwatch
display on the left, and operating time on the right.
This
also starts the timer, so hit the Right key again to stop it.
Hitting
the Cursor Left (Off) button resets the timer.
The HOLD ON warning is displayed when the transmitter is
powered
up with the Throttle hold switch (SW-1) on in the
helicopter
mode only. You can turn this off by moving the
SW-1 switch AFT (ELEV RUDD D/R switch). If you then get
the IDLE ON alarm (see above), you must move the Flt. Mode
switch fully FORWARD. For your safety, the transmitter
will
not broadcast until this alarm is ended.
