SLAvE CHANNEL POSITION
The Slave servo position next to OUT at the bottom left of the screen displays
in values from -100 to +100. 0 is neutral or center. This position represents the
servo travel that corresponds to the present Master channel position.
MASTER CHANNEL POSITION
The Master channel position displays on the bottom line of the screen next to
IN. It is expressed in values from 0 to 100. 50 is center or neutral. This position
represents the present Master channel position.
MIX TO THROTTLE
The 11X Cyclic-to-Throttle function adds throttle to prevent main rotor rpm decay
that results from load changes placed upon the engine when Aileron, Elevator or
Rudder is given. The most common use for Cyclic-to-Throttle mixing is for Stunt
Modes. This allows the main rotor rpm to remain consistent throughout aerobatic
and 3D maneuvers. Normally, Cyclic-control to-Throttle mixing is not used in
Hover (Normal) mode since control inputs are generally small and much less
aggressive.
Note:
If you are using a Governor for rpm control, it is not necessary to use the
Cyclic-to-Throttle Mixing. Further, all values should be left at the factory default
position (0%).
Programming the Cyclic-to-Throttle function
1 In Function mode highlight the Mix-Thro function. Press the Roller to
access the Mix-Thro screen.
2 Highlight the value you want to adjust, then press to open the options box.
Roll the Roller to adjust the value as needed.
SELECTING THE DESIRED fLIGHT
MODES fOR CYCLIC-TO-THROTTLE
MIXING
The 11X allows you to select the specific flight modes in which the Cyclic-to-
Throttle mixing will be active. The factory default position is ON for all flight
modes, which is not recommended in most cases. The Cyclic-to-Throttle mix is
generally used for Stunt (flight) modes only, so it will be necessary to select the
Cyclic-to-Throttle mixing for the desired flight modes.
1 Move the Roller to highlight the SW SEL for each of the Cyclic-to-Throttle
mixes to be used.
2 Press the Roller to open the Flight Mode options box. Highlight the desired
flight mode to be set (NRM, ST1, ST2, ST3, ST4, GEAR). Press the Roller to
turn the mixing on or off for each of the active flight modes.
4 Each gyro has 3 available gain settings. They are labeled Pos0, Pos1, and
Pos2 with a percentage next to each. They correspond to the positions of
a 3-position switch. 0 represents the switch being in the upper position; 1
represents the middle position; and 2 represents the lower position.
5 Use the Roller to highlight and select the number 0 position for each gyro
and set the percentage to the desired gain value.
6 Select the number 1 gain for each gyro and set it to the desired value.
7 Select the remaining gain values.
TRIM SYSTEM
The Trim System function adjusts the sensitivity of the 11X trim levers. The
standard digital trims are adjustable from 0–10 with 10 being the coarsest
adjustment and 0 being trim off. Adjusting the digital trim values has no effect on
the total trim travel, but affects the resolution of each trim input. When the value is
set to 10, each click of trim adjusts the servo output by 10ms and there are only
10 trim increments from center to each end. When set to 5, the output is changed
5ms per trim step and there are 20 trim increments from center to each end.
When set to 1, each click of trim changes the servo output by 1ms and there are
100 trim increments. When set to 0 the trim levers cease to function effectively,
turning off the trim function.
When adjusting the analog throttle trim, however, the total trim travel is actually
reduced when set to less than 100%. Use a fairly coarse setting, such as the
factory default 4, when test flying a model for the first flights in order to be able to
trim it quickly. Use a finer setting, such as 3–1, for final precision trimming.
Also in the Trim system function if flight modes are active, you can select the
flight mode trims to be common, the same set of trims in every flight mode, or
select FMOD to have a different set of trims for each flight mode. You can set the
Flap trim to on or off in the Trim System function as well. Finally, you can leave
the Flap and AUX levers at the default setting as well as CROSS, which swaps the
functions of the 2 levers.
L.S.T. TRIM
(LIMITeD STANDARD TRIM)
The L.S.T. trim feature has two options: L.S.T. and normal. In normal, when
making trim changes using the aileron, elevator or rudder digital trims, the
center and endpoints are affected by the trim values. The right trim causes the
center, right endpoint and left endpoint to all shift to the right. When L.S.T. is
activated, only the center position is trimmed. The center is shifted to the right
but the endpoints are not affected. This is useful for aircraft that have a hard
stop endpoint to prevent over-travel caused by trim or if it’s desired to have trim
changes not affect the total roll pitch or yaw rate.
To Adjust the Trim Rates
1 Highlight and select Trim System in the Function List to acquire the Trim
System function.
2 Highlight and select the trim you want to change. Use the roller to set a
value of 1–10 (1 = finest, 10 = coarsest).
3 Repeat for other trims as desired.
f-MODE DELAY
You can use the Flight Mode Delay function to delay the transition from a stunt
mode to normal flight mode. The delay function slows the selected channel’s
changes that are caused by switching from a stunt mode to normal flight mode.
Some of those changes include throttle curves, pitch curves, Dual Rates, etc.
This is useful for transitioning from a stunt mode with a V-pitch curve to normal
mode with a linear curve to slow the transition and prevent the helicopter from
jumping quickly.
To Program a f-Mode Delay
1 Highlight and select F-Mode Delay using the Roller in the Function List.
2 Highlight and select INH next to the desired channel to apply a delay.
3 Rotate the roller to adjust the setting from INH to 6.0 seconds.
GYRO GAIN SYSTEM
[SeNSOR]
The Gyro Gain system allows in-flight selection of up to 3 gyro gain settings
for up to two separate gyros, or up to three gyro gain settings assigned to flight
modes. The system provides for fixed gain values and has settings for normal or
tail lock gyros. You can assign and select Gyro gains via a three-position switch
or with Flight Modes.
If one set of gains for a gyro is set to 0% in normal gain mode, you can switch the
gyro off during flight.
GYRO CONNECTIONS
Plug the gain connector of one gyro into the AUX2 port of the receiver. Plug the
gain connector of another gyro (if used) into the AUX3 of the receiver. If using
only one gyro, connect its gain to either AUX2 or AUX3.
GYRO SENSOR
[GAIN]
In order for the Gyro Sens to appear in the Function List, you must program the
Device Select function to GYRO on the GEAR, FLAP, AUX2 and/or AUX3 channels
to be active.
Use this function only with gyros that have in-flight proportional gain adjustment
capability. Single and dual rate gyros that use a potentiometer to adjust the gain
will not work with this function.
To Access the Gyro Sensor
1 Highlight and select Gyro Sens. in the Function List.
2 Highlight MANUAL then decide which switch to use to control gyro gain.
Highlight and select AILE D/R, ELEV D/R, FLAP SW, AUX2 or AUTO (for
flight mode).
3 Two types of gyro adjustments are provided, Normal and Tail Lock. Highlight
and select the desired type of gyro. If selecting heading lock, note that a T
or N is available for each gain setting. If T is selected, the gyro will be in tail
lock mode. If N is selected, all values for that gain will be in normal mode.
For most airplane applications normal mode is recommended.
Note:
Time Lag is available in Tail Lock mode when switching from tail lock
to normal mode. This prevents the servo attached to the gyro from jumping
abruptly when switching from tail lock to normal mode.
To Select the L.S.T. Trim function
1. Highlight and select the L.S.T. or NORM setting next to the desired channel
(AILE, ELEV or RUDD). Press the roller to select L.S.T. or NORM.
2. Repeat for other channels as desired.
THROTTLE HOLD
The throttle hold function acts as a kill switch for glow-powered airplanes
and a safety/arming switch for electric-powered aircraft. You can also preset a
programmed throttle position for electric sailplanes to give full power when the
switch is activated. The throttle hold function switch position and direction is
assigned in Device Select. The programming of the throttle hold switch position
is done in the Device Select screen in System Mode.
Note: Throttle Hold defaults to the mix switch.
To Activate Throttle Hold
1 Highlight and select Thro Hold in the Function List to obtain the Throttle
Hold Display.
2 Highlight IHN and press the roller to activate the Throttle Hold function.
3 Highlight the HOLD Pos. and press the roller to allow throttle hold positions
to be adjusted (0% = low throttle low trim. 100% =full throttle).
Note:
The currently selected Throttle Hold switch displayed under ACT. MIX
SW is the default setting. To select another switch see Device Select Throttle
Hold on page 14.
THROTTLE TRIM
The Throttle Trim function allows a throttle cut feature that cuts the throttle to
an adjustable setting to kill the engine on a selected switch. An idle adjustment
feature is also available allowing 2 selectable idle positions through a switch.
To Program the Throttle Cut function
1 Highlight and select INH under THRO CUT.
2 Highlight and select the percentage next to THRO to adjust the position the
throttle moves to when the function is activated by a switch. Adjust this
position as necessary so the engine stops running, but does not bind the
throttle linkage.
3 You can add a Time Lag to delay the throttle cut function. Highlight and
select INH next to Time Lag and rotate the roller to select the desired Time
Lag. The value ranges from INH to 2.0 seconds.
