Page 124 HELI, SAIL AND MULTIROTOR THROTTLE CURVE In Heli Model Type, throttle curves are tied to the various flight modes. Each flight mode has a different throttle curve which must be set up individually. Throttle curves are called Motor Curves in Sailplane and Multirotor menus. When the Sailplane Model Type, the motor must be assigned a stick or switch for the Motor Curve menu to appear in Model Adjust.
Page 125 THROTTLE HOLD Throttle Hold must be enabled in Model Setup, Flight Mode Setup by selecting a Hold Switch. Once enabled, Hold appears as one of the flight mode options in the Throttle Curve and Pitch Curve menus. The throttle hold flight mode has two main components, the throttle curve and the pitch curve.
Page 126 The throttle hold should be programmed for zero throttle for electric helicopters, and engine idle speed for fuel powered models. Throttle hold serves three purposes for heli pilots: 1. Model helicopters can be extremely dangerous if the throttle is inadvertently bumped.
Page 127 TIP: Always fly with a finger on the throttle hold switch and be prepared to activate it at any moment in case of an out of control model or unexpected obstacle in the flight path. Activating throttle hold immediately eliminates power to the rotor blades. Always activate throttle hold prior to a crash to help limit damage to the aircraft components.

Creating a mix to RAL (Right Aileron) or LAL (Left Aileron) will create different results and enable you to use fewer mixes to achieve the desired response. Example 1: Creating a mix AIL >...
Page 143 SAILPLANE PRE-CONFIGURED MIXES When Sailplane is selected as the model type, the iX20 will pre-configure four commonly used mixes. For the following mixes, it is normal to set the offset close to or at the end point because of the geometry of sailplane flap servo linkages. It is also normal to use a significant amount of trim on the flap channels to center the control surfaces with these configurations.
Page 144 Aileron to Flap (AIL > FLP) The Aileron to Flap mix allows the entire trailing edge of the wing (aileron and flap) to operate as ailerons. When active, as aileron is applied, the flaps also move. Always program the flaps to move in the same direction as the turn (right aileron input moves the flaps as right ailerons).
Page 145 Flap to Elevator (FLP > ELE) Flap to Elevator mix prevents pitch up tendency that occurs when Crow or Butterfly mixing is applied. This mix is typically used only with the Camber System. The Flap to Elevator mix operates as a curve so the elevator response can be matched to specific points in the spoiler stick travel. This enables the pilot to ensure the elevator compensation is correct throughout the flap range.

Page 164 4. If necessary, add any required elevator mixing for each of the switch positions by touching in the Elev value box and sliding the circle along the bar. This pre-defined mix compensates for pitch changes that occur when the flaps are deployed. The elevator compensation should be tuned so the model maintains level flight at each flap position.
Page 165 5. Adjust the flap speed to slow the flap movement for more realistic operation or to help prevent a rapid change in flight characteristics when the flaps are deployed. Flap speed options range from 0.0 to 360 seconds. The value selected is the amount of time it will take for the flaps to move from one switch position to the next.
Page 166 PITCH CURVE The Pitch Curve menu is available by default for helicopter model types. Pitch curves are tied to the flight modes because they are often tied to complicated mixes. The graph represents how the pitch output command will respond to the pitch stick movements. On the graph, the horizontal axis represents the movement of the throttle stick, and the vertical axis represents the pitch command.

Page 173 SWASHPLATE The Swashplate menu applies to models that require swashplate mixing at the transmitter. Swashplate is available when the Model Type is Helicopter and the Swashplate Type is set to anything other than Normal in Model Setup. This menu manages swashplate mixes not commonly used with flybarless control systems, which handle mixing on the model.
Page 174 Below is a common 3D swashplate setup for models using swashplate mixes: Swashplate Type 1. From Model Setup, touch to select the correct swashplate type. 2. Adjust servo horn positions so they are neutral at center stick (zero pitch). 3. Connect the linkages with the collective pitch stick centered (zero pitch).
Page 175 6. Use servo reversing to ensure the swashplate is moving correctly for each control input. At this step, the swashplate does not have to respond in the correct direction, but it is critical it tilts correctly with pitch and roll and moves up and down with pitch. 7.
Page 176 ELECTRONIC E-RING Electronic E-Ring prevents over driving servos by limiting servo travel if the sum of your cyclic and pitch inputs exceeds servo limits.
Page 177 ELEVATOR COMPENSATION The Elevator Compensation setting allows for adjusting the reaction time of the aileron and pitch servos in a 120° swashplate setup. This allows for all 3 servos to reach full travel at the same time. Select a number from the popup menu to adjust the delay of the aileron and pitch channels with elevator input.

Page 190 TAIL CURVE Helicopters without a heading hold gyro will experience inconsistent tail performance. When throttle is applied, the tail will swing one way and then another with reduced power. Tail curves are used to compensate for torque at various points in the throttle range. Tail curves are commonly tied to flight modes and tuned to match each mode after the pitch and throttle curves are set.
Page 191 CAMBER PRESET The Camber Preset menu is activated when the model type is set to Sailplane and when one of the multi-servo wing types is selected in Sailplane Type in the Model Setup menu. The Camber Preset function allows for programming of the ailerons, flaps (if assigned), wing tips (if assigned) and elevator for a specific position in each flight mode.
Page 192 The OTF settings allow for the use of one of the trim buttons to fine tune each of the aircraft camber On The Fly (OTF) Trim Function settings while in the air. See the section for more information. The Speed setting enables the control surfaces to transition over a period of time, up to 120 seconds, when the flight mode is changed.
Page 193 CAMBER SYSTEM The Camber System menu is activated when the model type is set to Sailplane and when one of the multi-servo aileron wing types is selected in Sailplane Type in the Model Setup menu. The Camber System allows camber adjustment in flight and is used as the braking system. Each flight mode can have the camber system assigned differently and can use different input controls for each.
Page 194 IN-FLIGHT CAMBER CONTROL Each flight mode can have an independent configuration with different offsets and travel. Some flight modes may have a small range of camber (drooped trailing edge), while others may have a small range of reflex (raised trailing edge). Common practice is to have some flight modes utilize a small amount of travel for fine trailing edge control and some flight modes to use a large amount of travel to act as flaps.
Page 195 IN-FLIGHT BRAKING In-flight braking requires simultaneous flap and aileron deployment in order to create drag and slow the aircraft. These complicated mixing functions are often referred to as Crow or Butterfly. Crow is a flight mode where the flaps deploy and the ailerons reflex upward. The sailplane is put into a steep dive before crow is deployed, and even the fastest, most streamlined sailplanes can be landed slowly, with precision.
Page 196 For example, a basic 3 flight mode setup on an electric sailplane with a 4 servo wing may be configured so that: • In launch mode: The spoiler stick operates the motor as a throttle stick for the motor. Camber is controlled from a slider and is mixed to ailerons so the flaps and ailerons work together as flaps.
Page 197 • In land mode: The motor is disabled using the motor cut menu. The spoiler stick deploys crow. - At high stick the camber is neutral. - As the stick is moved down, the flaps are dropped and the ailerons are reflexed up. - A flap to elevator mix provides down elevator as the crow is applied to compensate for pitch changes.

Page 273 RANGE TEST The Range Test menu is used to confirm that receiver installation is working. From Model Setup, touch Range Test. Follow the on-screen instructions to perform a range test. This test should be performed multiple times from multiple model orientations to verify the radio component installation.
Page 274 In addition to watching if the model loses control, more specific data is available from the receiver to learn how well the installation is working. Telemetry receivers report the receiver performance directly in this menu as well as on the Spektrum Airware dashboard telemetry screen; receivers without telemetry can use the Spektrum Flight Log (SPM9540).
Page 275 TIP: It is important to note the flight log data is reporting the reception quality of the Spektrum signal received at the model. It does not represent the telemetry link strength. The control link can take advantage of multi-link technology, while the telemetry signal cannot.
Page 276 GUIDELINES FOR DSM2 INSTALLATIONS • It is normal to have as many as 50–100 antenna fades during a flight. • If the RF link is performing optimally, frame losses per flight should be less than 20. • Holds are unacceptable. If a hold occurs, investigate and correct the issue before next flight.
Page 277 GUIDELINES FOR DSMX INSTALLATIONS • Use fades for comparison only. All attached receivers should have similar fades. If not, investigate poorly performing receivers (location, antenna orientation, etc) and correct. • In conventional models during a normal flight, frame losses should be less than 100 on all receivers. •...
Page 278 RECEIVER INSTALLATION Always install receivers where the antennas are placed as far possible from metal, batteries, wires, fuel tanks and other objects. Receivers with integrated telemetry should be installed with a focus on the antennas attached to the main part of the receiver in an optimal location, as this will be the only antenna transmitting telemetry information.
Page 279 MODEL START WARNINGS Model Start Warnings are used to warn of the state of specific modes or features that are active when RF is powered on. Three trigger options are available: • STICK INPUT: Triggers the alert based on movement of one of the analog control inputs. •...
Page 280 By default, the system warns when attempting to power on the RF signal with the throttle stick over 10% by speaking “Throttle High.” Multiple model start warnings can be configured.

Page 285 Cross Fire system requires the Cross Fire serial port adaptor (SPMA3090, not included). Consult the manufacturer’s manual for use of any external RF device. Horizon Hobby does not provide support for external RF devices connected to the iX20 transmitter.
Page 286 SPEKTRUM RF The touch switch defines whether or not Spektrum RF is transmitted along with the data stream coming from the data port when other protocols are selected. The switch defaults to on when the Protocol is set to Inhibit.
Page 287 SERIAL PORT POWER (9.5V) The Serial Port will provide 9.5V for external devices by selecting the touch switch. This power supply has been designed to support up to 1 amp of current. Battery use will be affected and the expected use time will decrease when using this option to power external devices. Set the Transmitter Battery Warning alarm in System Settings, System Configuration to 25% when powering external devices through the serial port to ensure there is ample reserve battery time to support current demands and ensure safe operation.
Page 288 AIRCRAFT TYPE Aircraft Type defines what type of model configuration the iX20 is set up to control. Therefore, this menu should be the first step after creating a new model. The choices made in this menu define default channel assignments and enable pre-defined mixes with custom menus designed specifically for the selected application.
Page 289 AIRCRAFT TYPE (AIRPLANE) Wing Tail Choose from eleven common airplane wing Choose from ten common configurations for control configurations. The default configuration rudder and elevator. is Normal, which is a single aileron servo Similar to the elevon options above, there are configuration.
Page 290 Most pilots use Normal (low throttle to the bottom of transmitter). For pilots who use reverse throttle (low throttle to the top of the transmitter, high throttle to the bottom), the iX20 can be configured as such for correct operation.

Page 295 GPS technology* to hold a position and the pilot can move the pitch/roll control stick to guide the camera gimbal without affecting the multirotor. *GPS technology for position hold are not part of the features of the iX20. This function must be installed on the flight controller onboard the aircraft.
Page 296 FLIGHT MODE SETUP Flight Modes can help a pilot manage a wide variety of switches and functions. Pilots can use flight modes to manage rates, expo, mixes, audio alerts, and other functions. By defining several flight modes, pilots can maximize the aircraft’s performance using different configurations without having to use multiple switches.
Page 297 EXAMPLES OF FLIGHT MODE APPLICATIONS Acro: Airplane pilots can take advantage of flight modes to manage different phases of the flight, instead of having to operate different switches. For example, a scale airplane might have a flight mode for take-off with a few degrees of flaps, no elevator compensation, landing gear down, and low rates.
Page 298 the speed the helicopter responds also changes with head speed. By putting all of the related functions in flight modes, every function can be tailored to work correctly with the other settings in that mode. Sailplane: Sailplane pilots commonly use flight modes to define a wide array of configurations, which can have a drastic impact on how a high performance sailplane flies.
Page 299 USING FLIGHT MODE SETUP Assign a single switch for up to three modes. Swipe up the right side of the screen to scroll to the bottom of the menu and change the text-to-speech flight mode name or re-assign the currently selected switch position to a different flight mode.
Page 300 Adding another switch will add more flight modes to the flight mode assignment table: • Switch 1 will move the flight mode selection left or right in the table. • Switch 2 will move the flight mode selection up or down in the table. •...
Page 301 • The Priority Switch can override the table. One switch position will always be Switches. This position uses switches 1–3 to choose between the flight modes in the assignment table. The other switch positions can be assigned to specific flight modes.
Page 302 HOLD (HELICOPTER) Hold, commonly referred to as throttle hold, is a flight mode that allows the pilot to eliminate power to the rotor blades while maintaining cyclic and blade pitch control. Hold is enabled in the Flight Mode Setup menu and is configured in the Model Adjust, Throttle Curve and Pitch Curve menus.
Page 303 To enable the throttle hold function, touch the Hold Switch drop down menu button to select the desired switch. Select the switch position(s) to activate Hold. After the Hold mode is enabled in the Flight Mode Setup, the curves can be adjusted in the Throttle Curve and Pitch Curve menus.
Page 304 TRIM SETUP Use the Trim Setup menu to change the size of the trim step and the trim type.
Page 305 Trim Step: Adjusting the trim step value determines how many “clicks” of trim you input each time you press the trim button. Changing the trim step value to 0 disables the trim for the channel. To change the trim step value: 1.
Page 306 Trim Type: The two types are Common (default) and F-Mode. Common trim type maintains the same trim values for all flight modes. F-Mode trim type enables you to save trim values for each individual flight mode. For example, if an aircraft requires aileron trim in flight mode 1 but not in flight mode 2, use F-Mode trim to add the required trim in flight mode 1 and not affect the other.
Page 307 Trim Assignment: In some instances, such as airplane model type throttle, trim input may be reassigned to a different location.
Page 308 CROSS TRIMS Normal and Cross trim options are available. Normal trims align with the control stick; for example, the throttle trim is next to the throttle stick. Cross trims swap the position of the trims; for example, the throttle trim is next to the elevator stick and vice versa.
Page 309 MENU SETUP The Menu Setup option allows for customization of many of the menus in the iX20 by specifying a receiver, channel count or activating other options.
Page 310 The My List button is configurable for each model Receiver: Touch the receiver button to select the Spektrum receiver being used from the popup menu.
