Mixing functions support:
Mixing a channel to another channel. Mixing a channel to itself. Assigning offset to a channel. Linking primary to secondary trim. Rudder to Aileron/Elevator These mixes are available for each model memory:
14 programmable mixes Cyclic to Throttle (HELI) Swashplate (HELI) Elevator to Flap (ACRO) Aileron to Rudder (ACRO)
(ACRO) Aileron>Rudder (SAIL) Aileron>Flap (SAIL) Elevator>Flap (SAIL) Flap>Elevator (SAIL) When you choose a new programmable mix you can select from either a normal mix or a curve mix. Specialized mixes will populate the mixing menu, and change based on aircraft type and wing type selections. Each specialized mix has specific features for its intended function. Normal Mix On the second line select a channel for master control on the left and slave on the right. Inputs for the master channel control both the master and slave channels. For example, Throttle > Rudder makes Throttle the master channel and Rudder the slave channel. A channel monitor at the bottom of the screen shows how channels respond to input during setup. To view a mix on the monitor, the mix switch must be in the active position or the switch set to ON. Rate Change the rate value to control the travel and direction (positive or negative value to reverse) of the slave channel. Offset Change the Offset value to move the effective center position of the slave channel. Positive or negative value determines the direction of the offset. Offset is not available for curve mixes. Trim If the master channel trim should also adjust the slave channel, set Trim to Act. Curve (Page) The Curve value corresponds to each page of values assigned to a switch position. Leave the Curve value matching the highlighted box below the switch position for a basic configuration. Switch Select the switch you wish to use to activate the mix. The black box indicates the switch position where the currently displayed curve page is active, and the tick below the boxes indicates the current switch position. Select ON if you wish to activate the mix full time and do not want to use a switch. TIP: Use Auto Switch Select to select the switch. CAUTION: Always do a Control Test of your model after changing mixes. 32 SPEKTRUM NX20 TRANSMITTER INSTRUCTION MANUALEN Curve Mix If you want to be able to assign the output channel to respond on a curve or act as a switch, the Curve mix option will enable you to move the output channel to any value at up to 7 points along the travel of the input channel. Below the curve values, select a channel for master control on the left and slave on the right. For example, Throttle > Rudder makes Throttle the master channel and Rudder the slave channel. A channel monitor at the bottom of the screen shows how channels respond to input during setup. To view a mix on the monitor, the mix switch must be in the active position or the switch set to ON. Trim If the master channel trim should also adjust the slave channel, set Trim to Act. Curve The Curve value corresponds to each page of values assigned to a switch position. Leave the Curve value matching the highlighted box below the switch position for a basic configuration. EN Switch Select the switch you wish to use to activate the mix. The black box indicates the switch position where the currently displayed curve page is active, and the tick below the boxes indicates the current switch position. Select ON if you wish to activate the mix full time and do not want to use a switch. TIP: Use Auto Switch Select to select the switch. CAUTION: Always do a Control Test of your model after changing mixes. Curve (Page) Advanced Configuration Options The Curve selection in either Normal or Curve mixes can enable you to set up to 9 different settings pages. Curve settings within one mix do not carry over to other mixes. This can be useful if you want to test mixes and not have delete current configurations, or can come into play when using numerous flight modes, with this option there can be a separate mix page for each flight mode. To select the page you want to adjust:
1. Assign the switch and begin with your first switch position. 2. Scroll to the Curve option and change the value to the number you want for that Curve (page). 3. Scroll to the box above the active switch position and press the scroll wheel to assign the Curve (page) to that switch position. 4. Move the switch(es) to the next position you want to configure, select the Curve (page) you want to use, and repeat the process. Sequencer The Sequencer menu option provides this-then-that mixing with a time delay. Four sequences are available to control two functions each (A and B), in 2 timing directions (forward or reverse). Sequences appear throughout function screens as assignable switches. CAUTION: Always review the action of a sequence on the Monitor screen BEFORE operating the model to ensure controls act as desired. Failure to do so could cause a crash, resulting in property damage and or injury. You can program multiple functions to sequentially activate in response to an assigned switch. For example, an assigned Gear switch can open gear doors, lower the gear, then close the doors. In reverse, gear doors open, the gear retracts and the gear doors close. You can assign each Sequencer function to a switch in most Function screens such as Flight Mode, Dual Rate, Mixing, Throttle Curve, Pitch Curve, etc. You can assign several functions to a sequence to decrease the number of controls you need to touch during complex flight transitionsfor example, applying your assigned dual rates and exponential when the landing gear deploys and the flight mode changes. If you select an S-Number-A sequence (e.g. S3A), the sequence operates as a timed 5-position switch. An S-Number-B sequence operates as a timed 3-position switch. The 5 positions correspond to the sequencer values shown on the time delay graph in the second Sequencer screen. In a function screen, highlight each point (04) and select the switch position desired for a function to be active. When S1B (or another sequence-number-B) is selected as a switch in a function, the sequence will operate as a timed 3-position switch. The 3 positions act as kick points of the movement at fixed percentages (equal thirds) of the sequencer output. In a function screen, highlight each point (02) and select the switch position desired for a function to be active. Sequencer Set Up 1. In the first Sequencer screen, select 1 of the 5 available sequences. 2. In the second Sequencer screen, assign a switch to the sequence. We recommend using a 2-position switch. 33 SPEKTRUM NX20 TRANSMITTER INSTRUCTION MANUAL For example, you may move points 1, 2 and 3 closer to the beginning of the sequence so the motion occurs earlier. This results in a delay between point 3 and point 4 at the end of the sequence. Testing the Sequence The Sequencer function determines the response for channels included in the sequence. Refer to the Monitor screen to see how respective channels interact in the Sequencer. TIP: If you need to use a 3-position switch, you must assign one direction to two adjacent switch positionse.g., 0 and 1. Assign the opposite direction to the third switch position. 3. Assign the timing for the Forward and Reverse directions as desired. There is no delay when you use the Nor option. You may also select a delay time between 0 and 30 seconds. 4. Assign names for each sequencer function as desired. 5. Select either Step (S) or Proportional (P) for the Sequencer output. Step: The sequence only changes at kick points. Otherwise, there is a delay in the sequence until it reaches the next kick point. Proportional: The sequence movement is proportional between kick points. The sequence maintains rate and direction until it reaches the next kick point. 6. Adjust the Sequencer motion percentages in the third screen. Range Test The Range Test function reduces the power output. This allows for a range test to confirm the RF link is operating correctly.

NOTICE: Refer to your helicopter, gyro and governor manuals for programming recommendations. To change the Helicopter Icon:
From the Collective Type Screen, select NEXT at the bottom right of the screen. This will access the Heli image screen. Scroll to the icon and click once. Roll the scroll wheel left or right for optional icons. Swash Type The Swash Type menu option assigns the swash type for your particular helicopter model. Select the Swash Type before completing any programming in the Function List. The Swash Type will affect menu options in the Function List. Collective Type The collective type is used to turn on Pull collective for reversed collective. Available settings are Normal and Reverse. Press NEXT from the Swashplate Type screen to access the Collective Type screen. The Collective Type allows the throttle/pitch stick to operate in reverse and ensures trims, curves and all other functions that are to work in reverse function properly. Pitch Curve This function supports adjustment of collective pitch in 5 flight modes. To adjust the Pitch Curve:
1. Select the Pitch Curve you wish to edit (N, 1 or 2). 2. Scroll right to select the points on the curve and edit the respective values. 3. Press the BACK button to save the Pitch Curves and return to the Function List. 42 SPEKTRUM NX20 TRANSMITTER INSTRUCTION MANUALEN Swashplate The Swashplate menu option enables you to adjust the following:
Swashplate Mix Exponential E-Ring Elevator Compensation Use positive or negative Swashplate mix values as needed for correct direction response of the helicopter. Before making adjustments to the Swashplate mix, make sure the throttle/collective pitch input moves the entire swashplate up or down. If the servos are not moving in the same direction, reverse them as necessary in the Servo Setup menu option. When the entire swashplate moves up or down:
1. Adjust the mix value for the Aileron and Elevator channels. If the servos do not move in the correct direction, change the direction of the mixfor example, a positive value instead of a negative value. 2. Adjust the mix value for the Pitch. If the swashplate does not move in the correct direction, change the direction of the value
(negative instead of positive). Gyro The Gyro menu option enables you to assign a gyro gain value to an independent switch or a Flight Mode. Assign the receiver channel connected to the gyro, then assign the switch for gyro options. You can also assign values to available switch positions
(from 1 to 4 rates are available, depending on the switch assigned). Make sure the gyro operates correctly and compensates in the correct direction. Tail Curve The Tail Curve function mixes tail rotor input with the throttle/
collective function to counter torque from the main rotor blades when using a non-heading hold (tail lock) gyro or when using rate mode on a gyro. See Pitch Curve for more information on programming curves. Mixing Cyclic to Throttle Cyclic to Throttle mix prevents rpm loss when aileron, elevator or rudder inputs are given. This mix advances the throttle position with cyclic or rudder control to maintain rpm. At full throttle, Cyclic to Throttle mixing prevents the throttle from over driving the servo. IMPORTANT: Do not use Cyclic to Throttle mix when using a governor. To verify that the Cyclic to Throttle mix is working properly and in the correct direction, move the flight mode switch to one of the active positions. Move the programmed cyclic or rudder channel, noting the throttle position. The throttle position should increase. If the throttle decreases, then the opposite value (positive vs. negative) is needed. Always enable Expo when using a standard rotating-arm servo. The Expo delivers linear movement of the swashplate from a standard rotary servo. When Expo is inhibited, the arm on a rotary servo moves on a curved path with decreased swashplate movement at the extremes of the servo arm travel. NOTICE: Do not enable Expo when using a linear servo. Electronic E-Ring This feature prevents over driving servos by limiting servo travel if the sum of your cyclic and pitch inputs exceeds servo limits. Swashplate The Swashplate Mix typically corrects swashplate timing issues by mixing Aileron to Elevator and Elevator to Aileron. When adjusted correctly, the Swashplate causes the helicopter to roll and pitch accurately with minimal interaction. 43 SPEKTRUM NX20 TRANSMITTER INSTRUCTION MANUALEN SAIL (SAILPLANE) CAUTION: Always do a Control Test of your model with the transmitter after programming to make sure your model responds as desired. NOTICE: Refer to your sailplane manual for recommended control throws. Sailplane Type Use the Sailplane Type Screen to select wing and tail types to match your sailplane model. Diagrams and setup names show on the transmitter screen to show the available setups. Refer to spektrumrc.com for more information about new NX20 Spektrum AirWare updates to support these options.

Sailplane Image In the Sailplane Type screen, select NEXT at the bottom right of the screen. This will access the Sailplane Image screen. Click once on the image and roll the scroll wheel left or right to for optional images. Camber Preset Camber Preset is only available when a 2 aileron servo wing type is selected in Sailplane Type. The Camber Preset function enables you to program the ailerons, flaps, wing tips and elevator for a specific position in each Flight Mode. If flight modes are not active, only one preset position is available and it is always active. The Camber Preset Speed enables the control surfaces to transition over a period of time, up to 30 seconds, when you change flight modes. Move the flight mode switch to the desired position to change the Camber Preset values. Camber System Camber System is only available when 2 aileron wing type is selected in Sailplane Type. The Camber System allows in-flight camber adjustment and is also used as the braking system, often referred to as Crow or Butterfly. The Camber System enables you to assign the Camber System to a different switch in each flight mode. 44 SPEKTRUM NX20 TRANSMITTER INSTRUCTION MANUALEN SAIL Mixing For each of these mixes, you can program each flight mode with different mix values or at 0% if no mix is desired for that specific flight mode. Programming values include independent control of the direction and amount a slave surface moves in relationship to the master surface. Aileron to Rudder The Aileron to Rudder mix is commonly used for coordinated turns. When active, as aileron is applied the rudder moves in the same direction as the turn (right aileron input results in right rudder output). If you assign the flight mode to a switch, a Sub Switch option allows you to assign an additional switch to activate up to 3 Aileron to Rudder mixes for that flight mode. Aileron to Flap 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 (so that right aileron is equivalent to flaps moving as right ailerons). Elevator to Flap Elevator to Flap mix creates additional lift, allowing a tighter turn. The entire trailing edge of the wing (aileron and flap) operates as flaps (camber increase) when you apply elevator. An offset is provided, which is typically used for Snap Flaps. With Snap Flap, no Elevator to Flap mix occurs until the offset value is reached. Typically, this offset is at 70% up elevator so that beyond 70%
the down flap mix comes in, providing additional lift for more aggressive turning (for tight thermals or racing turns). Flap to Elevator Flap to Elevator mix prevents pitch up tendency that occurs when you apply Crow or Butterfly. This mix is typically used only with the Camber System. The Flap to Elevator mix operates as a curve so that the elevator moves down the most during the first 20% of flap deployment, decreases over the next 40%, then remains the same from 60 to 100% of flap travel. For sailplanes with ailerons/tips/flaps, make sure an appropriate Sailplane Type is selected so that tips appear in the transmitter as RAIL and LAIL. Decrease or increase travel on the tip ailerons by creating an AIL > RAIL mix. V-Tail Differential The V-Tail Differential screen enables you to increase or decrease the amount of differential between control surface throws. Positive Differential values decrease the amount of down travel without affecting the up travel on the opposite control surface. Negative Differential values decrease the amount of up travel without affecting the amount of down travel on the opposite control surface. The V-Tail Differential menu option only appears when V-Tail A or V-Tail B is active in Aircraft Type. To adjust the V-Tail Differential:
1. Scroll to Switch and press the scroll wheel. Scroll right to select On (Differential is always on) or assign the differential to a switch position. 2. Press the scroll wheel a second time to save the selection. 3. Scroll to Diff: and press the scroll wheel once to change the value. 4. Press the scroll wheel again to save the selection. 45 SPEKTRUM NX20 TRANSMITTER INSTRUCTION MANUALEN MULTI (MULTIROTOR) CAUTION: Always do a Control Test of your model with the transmitter after programming to make sure your model responds as desired. NOTICE: Refer to your multirotor manual for programming recommendations. The Aircraft Options menu allows you to select a camera gimbal axis. Select None, 1Axis, 2Axis or 3Axis from the Camera Options box. The model icon can be changed by selecting the icon and scrolling left or right to select. Multirotor Image In the Aircraft Options screen, roll to the image. Click once on the image and roll the roller left or right for optional images. F-Mode Setup By default switch B is assigned 3 Flight Modes. You can assign up to five flight modes using any combination of up to two switches. Channel Assign Scroll and Select Channel to assign channel inputs and outputs for each Flight Mode. Each channel can be assigned any switch on the transmitter including but not limited to trim switches, gimbals and the Clear/Back buttons. EXAMPLE: Assign Flight Mode 1 to be your primary flight mode where your gimbals control primary flight axis. Switching to Flight Mode 2, you can have the gimbals control the camera axis and the trim buttons control primary flight axis. TIP: You can also access the Channel Assign from the Channel Assign Menu in System Setup. Trim Setup By default Trims are setup for F Mode, and the trim steps are defaulted to zero for multirotors. If you want to utilize trim in multirotor mode, increase the trim step values above zero. F Mode trim type enables you to save trim values for individual flight modes if you find, for example, the aircraft requires Roll trim in Flight Mode 1 but not in Flight Mode 2. D/R and Exponential Dual Rates and Exponential are available on the PIT, ROL and YAW channels. To adjust the Dual Rate and Exponential:
1. Scroll to the channel and press the scroll wheel once. Scroll left or right to select the channel you wish to change and press the scroll wheel again to save the selection. 2. Scroll to Switch and press the scroll wheel to select. Move the switch you want to assign to D/R. 3. Scroll to dual rate and press the scroll wheel. Scroll left or right to change the value and press the scroll wheel again to save the selection. Exponential affects control response sensitivity around center but has no affect on overall travel. Positive exponential decreases the sensitivity around the center of gimbal movement. 46 SPEKTRUM NX20 TRANSMITTER INSTRUCTION MANUALEN Motor Cut The Motor Cut menu option enables you to assign a switch position to stop the motor. Motor Cut activates regardless of Flight Mode. When you activate Motor Cut, the ALT channel moves to the pre-
programmed position (normally Off). You may need to use a negative value to move the ALT channel to the off position. CAUTION: Always test the model after making adjustments to make sure the model responds to controls as desired. Motor Curve You can use the Motor Curve menu option to optimize the throttle response. A maximum of 7 points are available on the throttle curve. To add points to a Motor Curve:
1. Move the throttle stick to the position where you wish to add the new point. 2. Scroll to Add Pt. and press the scroll wheel to add the point. To remove points from a Motor Curve:
1. Move the motor stick until the cursor is near the point you wish to remove. 2. Scroll to Remove Pt. and press the scroll wheel once to remove the point. If you program multiple throttle curves and you wish to edit one of the curves, that curve must be active in the Motor Curve screen before you can make any changes. 47 SPEKTRUM NX20 TRANSMITTER INSTRUCTION MANUALEN PHYSICAL TRANSMITTER ADJUSTMENTS The NX20 has all the physical transmitter adjustments located around the gimbal face of each gimbal. This arrangement allows for quick and easy adjustments with out taking the back cover off or removing any plugs to access adjustment screws. Available adjustments:
Change the Throttle Ratchet Change the Throttle Tension Adjust Stick Tension Adjust Stick Tension Turn the screws clockwise a small amount using a small Phillips screwdriver to tighten the stick tension and counter clockwise to loosen. NOTICE: Always do a test of stick tension while turning these screws to ensure stick tension is not too loose or too tight. Tightening a screw too much can damage a spring. Loosening a screw too much can let a spring fall off and cause short-circuit in the transmitter. Vertical Tension Horizontal Tension Horizontal Tension Vertical Tension Control Stick Length Adjustment 1. Using a 2mm Allen wrench, turn the setscrew in the stick counterclockwise to loosen it. 2. Make the stick shorter by turning it clockwise or longer by turn ing it counterclockwise. 3. After adjustment of stick length, tighten the setscrew. Gimbal Travel Limit Each gimbal has a switch at the top and bottom that can limit the travel on that sticks vertical movement. Adjusting the gimbal travel limits 1. Remove the covers 2. Move the switches toward the center of the transmitter to use the full travel available. Move the switch to the outside of the case to reduce travel. 48 Gimbal Travel Limit Switches Gimbal Travel Limit Switches SPEKTRUM NX20 TRANSMITTER INSTRUCTION MANUALEN Ratcheted Throttle Smooth Throttle Adjustment Ratchet 1. Locate the throttle strap adjustment screws on both gimbals. The ratchet set screw engages a serrated section on the gimbal for a ratcheted throttle, while the tension set screw engages a strap for smooth tension on the gimbal. 2. To engage the throttle ratchet turn the ratchet set screw clockwise until the ratchet engages. 3. To disengage the throttle ratchet turn the screw counter clockwise until the gimbal moves freely. Smooth Tension 1. To engage the throttle tension, turn the tension set screw clockwise until the Tension engages. 2. To disengage the throttle Tension turn the screw counter clockwise until the gimbal moves freely. Antenna Position We recommend setting up your antenna to be positioned vertical when you are in your most comfortable position for flying. The antenna may also be folded for storage. Ratchet Tension Tension Ratchet Mode Conversion You can select transmitter modes 1, 2, 3 or 4 for the NX20. Converting the mode requires both a programming and a mechanical change. Programming Conversion 1. Change the mode within the System Setup -> System Settings. 2. Calibrate the sticks within the System Settings menu. Mechanical Conversion Mechanical conversion is required to change between Modes 1 and 2 or between Modes 3 and 4. The mechanical conversion consists of the following steps:
1. Change the throttle ratchet/throttle tension; remove the tension on the side that was throttle, and apply the tension on the side that will be throttle. 2. Adjust the elevator centering screw. When changing between modes 1 and 2, or between modes 3 and 4, you must adjust the elevator centering screw. a. Hold the elevator or throttle stick in the full up or full down position when you are adjusting the elevator centering screw. Holding the gimbal stick reduces the load on the elevator centering mechanism and makes it easier to adjust the centering screw. b. Use a Phillips screwdriver to adjust the elevator centering screw. Tightening the screw will disengage the centering spring. Loosening the screw will engage the spring. IMPORTANT: Do not remove the mode change screws too far or you will have to open the case to put it back together.
