Stick Length Adjustment Stick Lever Tension Adjustment
You may adjust the stick tension of your sticks to provide the
"feel" that you like for flying. To adjust your springs, you'll have
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. Very carefully reinstall the rear cover.
When the cover is properly in place, tighten the six screws.
An 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 # xxxx.
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 lineup 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 button (the momentary
ENG CUT/TRAINER button on the top right 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 button is released, passing control to the
student's transmitter. If the student loses control, the instructor
can quickly "take over" by pushing down the trainer button and
controlling the model.
Operating with a Trainer Cord
To use the trainer cord:
You may change the length of the control sticks to make your
transmitter more comfortable to hold and operate.
To lengthen or shorten your transmitter's sticks, first unlock the
stick tip by holding locking piece B and turning stick tip A
counterclockwise. Next, move the locking piece B up or down
(to lengthen or shorten). When the length feels comfortable,
lock the position by turning locking piece B counterclockwise.

FLT.C Flight Conditions or "Idle-Up's"
Your Optic system's HELI menu provides three flight modes in
addition to the normal one (NOR). Within each condition, you
may program an independent set of dual rates, exponentials,
throttle and pitch curves, revolution mixing, and gyro gain.
In the HELI menus, these are automatically called up whenever
you switch to a new condition.
NOR is intended for hovering flight. ST1 may be used for
forward flight and mild aerobatics, ST2 may be used for inverted,
and ST3 is used for autorotations as it includes a throttle
hold feature which disengages the throttle servo from collective
commands. These conditions are activated whenever the model
memory is chosen to be HELI type
The defaults for the switches controlling these flight
conditions are as follows:
- NOR: ON when Flt. Mode (SW-3) Switch is BACK.
- ST1: ON when Flt. Mode (SW-3) Switch CENTER.
- ST2: ON when Flt. Mode (SW-4) Switch is FORWARD
- ST3: ON when SW-1 is DOWN. (For Throttle Hold only)
As these functions are switched on or off, ST3 = HOLD has
highest priority, followed by ST2 and ST1. Regular settings (NOR)
occur when all of the others are off.
Throttle and pitch curves, revolution mixing, and gyro gain may
be independently selected for each condition.
Here are some suggested starting settings if your instructions do
not provide any:

4. Call up the swash screen by repeatedly pressing one of the
Up Down EDIT buttons until the SWAH window appears.
The function is automatically active when you select 120'
mixing in the model setup menu.
5. If all the servos raise the swash with increasing collective,
go to the next step. If they lower the swash, press the
CURSOR Right button twice to get to the collective setting
menu (the arrow appears over the number 6).
Now press the DATA -Decrease button until the sign is
reversed in front of the percentage value. Now the swash
should properly respond to collective. If you've done the
wrong thing, you can reset the percentage by pressing the
Active/Inhibit (Clear) button.
6. If all the servos tilt the swash to the right with right aileron
stick, go to the next step. If they tilt the swash to the left,
press the CURSOR Right button once to get to the aileron
setting menu (the arrow appears over the number 1).
Reverse the sign in front of the percentage with the
DATA -Decrease button.
Now the swash should properly respond to aileron.
7. If all the servos tilt the swash aft with up elevator stick, go to
the next step. If they tilt the swash forwards, press the
CURSOR Right button once to get to the elevator setting
menu (the arrow appears over the number 2).
Now press the DATA -Decrease button until the sign is
reversed in front of the percentage value. Now the swash
should properly respond to elevator.
8. Double check that all three functions, collective, aileron, and
elevator, produce the desired result on the swashplate.
Do not set any SWAH values to 0% or you will disable the
response to that control!
