the Roller to access the point value, then roll the Roller to increase and
decrease the point value.
4. To set throttle curves for flight modes, switch the flight mode to the desired
position; the screen will change to that flight mode.
5. Highlight the pitch point you want to adjust and press the roller. Rotate the
roller to adjust that point on the pitch curve.
6. To add a point move throttle stick to the desired position until STOR appears
on the left bottom of the screen. Pressing STOR will save a new point at that
position.
Note:
To eliminate a point, press ERAS (bottom left of the screen) when the point
is highlighted.
PITCH CURvE
The Pitch Curve controls variable pitch propellers. The Pitch function works
nearly identically to a programmable curve mix, allowing you to store and adjust
up to 7 points throughout the curve. Two curves are available (Pos0 and Pos1)
and are selectable with various switches, flight modes, throttle position or Stick
positions (SPS). An Exponential function is available that smoothes the pitch
curve. Pitch must be assigned to Gear, Aux2 or Aux 3 channels in Device select
to access the Pitch function. The Pitch curve mixes the throttle channel to the
channel selected as PIT in the device select mode.
POINT NAMES/NUMbERS
The points you adjust list vertically by name (Point-L, 1, 2, H, etc.) and display by
number on the graph.
Change the value of a point by highlighting and selecting the point name and
adjusting the desired percentage.
CURRENT POINT SETTING
This list shows the setting for each of the 7 adjustable points (Point-L, 1, 2, 3, 4,
5, H). The value of each point determines where the point positions vertically on
the graph, dictating the Pitch servo position relative to the throttle. You can set the
point values be from 0 to +100.
To change a point value, highlight and select the Point Name to the left of the
point value, then adjust the desired value.
To reset original settings, highlight a point value then press CLR.
vERTICAL LINE
The vertical line on the graph shows the current throttle channel position. When
the throttle channel is turned fully in one direction, the line is to the extreme left
over Point-L. When it is at neutral, it is centered over Point-1 and when fully
deflected in the other direction, the cursor is at the extreme right of the graph
over Point-H. Where the vertical line intersects the Curve/Line over a given point
defines the pitch servo’s position, which is equal to the value assigned to that
point.
GRAPH
The graph illustrates the pitch curve. The X-Axis (horizontal plane) represents
throttle channel movement. The Y-Axis (vertical plane) represents the Pitch servo
movement.
POINTS YOU CAN ADD AND ADJUST
The Pitch Curve defaults to three points (L, 1 and H). You can add up to four
additional points. To add a point, move the throttle stick in the desired position
until STOR appears on the left bottom of the screen. Press STOR to save a new
point at that position.
Note:
To eliminate a point, highlight it then press ERASE (bottom left of the
screen).
EXPONENTIAL
The Exponential function blends the Curve between the points on the graph
to provide a smooth response. It defaults to OFF. To turn it on and smooth the
mixing curve, highlight and select OFF. It will toggle to ON.
PITCH CHANNEL POSITION
The Pitch servo position next to OUT at the bottom left of the screen displays in
values from 0 to +100. It represents the servo travel corresponding to the present
Throttle Channel position.
THROTTLE CHANNEL POSITION
The Throttle channel position appears on the bottom line of the display next to IN.
It displays in values from 0 to 100 with 50 being the center or neutral position. It
represents the present Throttle channel position.
SWITCH SELECT
There are numerous switches that can switch between Pos0 and Pos1. Note: If the
upper and lower settings for Pos0 or Pos1 are left at 0% the mixer can be turned
on and off with the switch. In addition, if Flight Modes are activated in the Device
Select function, flight mode switches may be selected. Also you can use Switch
positions (SPS) to select between Pos0 and Pos1.
To choose a switch that selects between the Pos0 and Pos1 values, highlight and
select the switch name. It will toggle between Pos0 and Pos1.
fLAP SYSTEM
The 11X features a three-position Flap System with Elevator and Aileron
compensation, programmable Delay, and an Auto Land feature. It allows you to
program the flaps to three different positions, normally full flap, half flap and no
flap or fully retracted position.
Note:
The Flap System is available in the Function List only if SYS is selected on
the OUT line next to FLAP in the Device Select function in the System List.
Because flaps generally cause a change in pitch (Elevator trim), the Flap System
provides for setting an Elevator deflection for each flap position. This is called
Elevator Compensation.
There is also a programmable Delay in .1-second increments up to a maximum
of 2 seconds. The Delay determines how long it takes for the Flaps and Elevator
to reach their positions. This delay function ensures the Flaps and Elevator
reach their positions at the same time resulting in smooth Flap deployment and
retraction with minimal pitch change.
The Auto Land feature, if implemented, automatically retracts the Flaps and
Elevator compensation when the throttle is raised above a specified throttle
position. This is useful during a missed landing approach when a go-around
is required. The Flap System allows the Flaps to deploy using the Flap Switch,
Flight Mode switch or a combination of both.
To Program the flap System
1. Highlight and select Flap System in the Function List to obtain the Flap
System display.
2 If using Auto Land, scroll to INH under AUTO THRO and select it with the
Roller. INH changes to 0 when selected.
3 Move the Throttle Stick between 0–100% to select where the Auto Land
feature is to retract the Flaps and Elevator compensation. The press STO at
the lower left corner of the screen to store the value.
We recommend the throttle position be set very high at first (between 90–99%) to
give the aircraft a chance to regain some speed before the Flaps actually retract.
As the Flaps retract, lift decreases and the stall speed of the aircraft increases
and may cause a crash if airspeed is too low. When there is a missed approach,
advance the throttle slowly up to about 90% and wait until the aircraft picks up
some speed before advancing the throttle to full, causing the Flaps to retract.
fLAP
The FLAP values correspond with how far the flaps deflect when in the NORM,
MID, and LAND positions. Generally the NORM position represents normal flying
where the flaps are fully retracted. The MID position is typically used for half flaps
and LAND for full flap for landing.
1. With the Flap switch in its uppermost (Normal) position (no flaps deployed),
scroll to the NORM parameter under FLAP on the display. Select the value
with the Roller and adjust its value to bring the flaps to their normal flying
position (no flaps deployed.)
2. With the Flap switch in the MID position, scroll to MID under FLAP on the
display and select it. Adjust the desired percentage to deflect the flaps to the
desired amount.
3. Put the Flap switch in the lowermost LAND position. Scroll to LAND under
FLAP on the display and select it. Adjust the percentage to deflect the flaps
to the desired position.
eLeV – eLeVATOR COMPeNSATION
The ELEV values represent the Elevator deflection that occurs when the Flaps are
deployed to their various positions. It requires some trial and error to attain the
exact values. Once properly adjusted, the aircraft will assume the proper pitch
attitude for all flap positions.
1. Adjust the Elevator compensation values (ELEV) as desired for each switch
position as you adjusted the flaps above.
AILe – AILeRON COMPeNSATION
The Aileron values represent the Aileron deflection that occurs when the Flaps
are deployed to their various positions. It requires some trial and error to arrive at
the exact values. Once properly adjusted, the aircraft will assume the proper roll
attitude for all flap positions.
1. Adjust the Aileron compensation values (AILE) to the desired values for each
switch position you adjusted the flaps above.
fLIGHT MODES
If you activated Flight Modes in the Device Select function, FM0, FM1 and FM2
appear along the right side of the Flap System display representing the 3 Flight
Modes. You must assign each of the Flight Modes one of the Flap values (NORM,
Mid, or Land). When that Flight Mode is selected during flight, the Flaps deploy
to that position. SW is also an option. When SW is selected, flap operation is
controlled by the Flap switch when in that Flight Mode.
If you did not activate Flight Modes, skip this portion of the Flap System.
1. For each Flight Mode, highlight and select FM0-FM2 and select either a
flap position (NORM, Mid, Land) for the flaps to assume when in that Flight
Mode, or select SW for the Flap switch to control the flaps.
