GYRO (Gyro Gain)
2. To set the mixing amount for the normal (NOR) flight mode,
flip the Flt. Mode (SW-3) switch all the way back, NOR will
be flashing on and off. Set the percentage to yield the
desired gyro gain (this is usually a high-gain setting).
If for some reason you want a 0% setting, press the Active/
Inhibit (Clear) button.
!
Tip
The following setups for gyro gain values in ST2, ST3 and
ST4 (Throttle Hold), are for advanced users flying in Idle-up
or stunt modes
RVMX (Revolution Mix)
RVMX Revolution Mix
The revolution mixing function mixes pitch commands to the tail
rotor in order to suppress the torque generated by changes in
the main rotor's pitch angle and rotational speed.
You can input independent values for revolution mixing above
and below one-half throttle for each of the NOR, ST1, and
ST2 flight conditions. Revolution mixing is disabled whenever
throttle hold (ST3, operated by switch SW -1) is on.
For a clockwise-turning rotor, revolution mixing should apply
right rudder when pitch is increased; for a counterclockwise
turning rotor, the opposite should occur. Remember to set the
value for both sides of the throttle stick's motion.
Revolution mixing has no preprogrammed values input at the
start. You will need to input values for your helicopter as
described in the setup example. Note: A procedure for adjusting
revolution mixing is given in a table at direction.
!
Tip
Revo mix is used with "Standard Rate Gyros" NOT
"Heading Hold" gyros.
1. Call up the revolution mixing screen by repeatedly pressing
one of the Up Down EDIT buttons until the RVMX window
appears. The function is active with 0% mixing turned on.
Put the throttle stick to its idle position.

3. Flip the Flt. Mode (SW-3) switch to its center position. ST1
will be flashing on and off. Set the percentage to yield the
esired gyro gain in this flight mode (this will usually be a
lower-gain setting for reduced damping during stunts).
4. Flip the Flt. Mode (SW-3) switch all the way forward. ST2
will be Flashing on and off. Set the percentage to yield the
desired gyro gain.
5. Now flip the SW-1 switch fully down. You may now input a
setting for ST3, throttle hold.
6. Make some test flights to try these settings out. Take note
of when more gain is need, and when less gain is needed.
You can adjust all of the gyro settings in each flight mode to
suit your machine.
2. Now press the DATA +Increase button. This will increase the
percentage of RVMX mixing for the low side of throttle.
You may set a value of 0% to 100% for this side. If you wish
to return the mixing percentage to the default 0% value,
press the Active/Inhibit (Clear) button.
3. Move the throttle stick to a position above half-throttle, and
change the percentage number to suit.
4. Now verify that the rudder responds both the correct
direction and amount for travel on both sides when throttle
is commanded.
5. Set up the RVMX values for the other flight conditions
(ST1, ST2) by flipping the Flt. Mode (SW-3) switch and
repeating these procedures.
HOLD (Throttle Hold)
HOLD Throttle Hold
The Throttle Hold function moves the engine throttle servo to a
selected position near idle, and disengages it from the throttle
stick. It is commonly used during autorotation, and activated
with the SW-1 switch on the left front of the transmitter.
You can set the throttle position to be held over a -25 to +100%
range centered about the throttle idle position. Activating throttle
hold also disables revolution mixing (RVMX).
1. Press one of the Up Down EDIT buttons until the H0LD
window appears. The default is for the function to be inhibited.
To activate the throttle hold function, press both DATA buttons
at the same time. This will cause the flashing INH display to
change to a 0% value.
SWAH (120 Swash Plate Programming)
SWAH 120 Swash Plate Programming
The Swashplate menu is intended only for helicopters whose
collective pitch is controlled by more than a single servo at a
time, and is sometimes referred to as CCPM
(Collective & Cyclic Pitch Mixing).
The Optic contains settings for 120¡Æ swashplates.
Consult your model's setup instructions to find out whether you
need special swash settings.
The swashplate menu is used to control the response of all
three collective servos as a group. It should NOT be used for
reversing or individual servo travel adjustment. Perform these
settings in the REV and EPA menus respectively. When you
move the collective stick, all swash plate servos should move in
the same direction with the same amount of up and down travel
without tilting the swash plate.
If the swashplate should tilt to one side when you command
collective, one or more servos is moving the wrong direction
or the wrong amount, and must be adjusted in the SWAH menu.
If the swashplate moves down when pitch should be increasing
or vice versa, change the sign in front of all three servos from
(+) to (-) or vice versa. Note that there is no SWAH menu when
the NOR menu is selected, but the 120¡Æ swash type does
contain the SWAH menu.
The swash default settings are shown below.

2. Now you can adjust the throttle hold position with the DATA
+Increase or -Decrease buttons, anywhere between -25 to
+100% (to return to the default 0%, press the Active/Inhibit
(Clear) button).
3. Check that your throttle goes to the desired hold position by
flipping the SW-1 switch one way and the other.
Adjust the number as needed. Be sure to choose an engine
speed that's fast enough to keep the engine from accidentally
quitting, but slow enough to not engage the main rotor clutch.

Swashplate Programming
1. Consult your model's setup instructions. If three servos are
needed to move the swashplate in a 120¡Æ CCPM set-up,
go to the model setup instructions on page 37 and select
the 120¡Æ swash type.
2. With all the servos hooked up, and the transmitter and
receiver turned on, move the throttle/collective stick up and
down. The swash should move up and down with no
rotations.
Move the aileron stick left and right. The swash should tilt
left and right without pitching or rising. Move the elevator
stick. The swash should tilt fore and aft with no rotations.
If there are rotations when collective is moved, or the swash
moves up and down with aileron or elevator, you need to
adjust the settings in the swash menu.
3. If the servos do not all respond in the same direction for
collective or opposite directions for aileron and elevator, you
will need to reverse one or more of them in the reversing
menu (REV). It may take a little trial and error trying different
combinations of normal and reverse rotation to get the
