Pitch Curve Adjusting the Normal Pitch Curves The DX6 offers three independent pitch curves with three adjustable points per curve. This function allocates a separate pitch curve setting during Normal, Stunt, and Throttle Hold modes to maximize flight performance. Once the pitch curves are established, each can be activated in flight, using the two-position flight mode switch and the throttle hold switch. Each of the three points on the pitch curve are independently adjustable from 0–100%.
Throttle Curve Adjusting the Normal Throttle Curve Adjustment of the throttle curve is very similar to the pitch curve adjustment described in the preceding section. Two throttle curves are available—normal and stunt. The normal or hover throttle curve has three points (L,2, H) and the stunt or flight throttle curve has two points (L and 2). The two throttle curves are activated by the flight mode switch located on the top left rear corner of the transmitter.
Important Gyro Information Note: After flight trimming the helicopter, or anytime the rudder trim is changed, It is important to rebind the system (see Binding page 60) to set the fail-safe position to the rudder’s true neutral. With many types of gyros, each time the radio is turned on the gyro senses the servo output position and establishes this as the center for that flight.

Charging the Transmitter Transmitter It is important to fully charge the transmitter battery prior to each flying session. The charger supplied with the system (SPM7105) is designed to recharge your transmitter battery at a rate of 50mA. For the initial charge, or if the transmitter hasn’t been used for several months, it’s important to charge the transmitter battery for 24 hours to achieve a full charge. Subsequent charges of 10–12 hours (approximately overnight) are recommended.
Trainer System The DX6 features a built-in trainer system. The transmitter can be used as either a master (trainer) or as a slave (trainee). The DX6 is compatible with all other Spektrum™ and JR® radios that have built-in trainer systems. An optional Trainer Cord (SPM6805) is needed. ������ ������������ ����� �������������� �������� ������������ ��������� ��������� ��������������� �������� ���������������� Operating the Trainer System 1.

CHAPTER 1: TRANSMITTER CONTROLS DIGITAL TRIM LEVERS The DX6 features four digital trim levers with a direct trim display feature for ultra precise adjustments. When a trim input is given, the display screen will automatically change to show the trim value for current channel being adjusted. Once the trim change has been completed, the screen will automatically return to the previous screen display after 2–3 seconds.
LITHIUM BATTERY Note: The DX6 has a 5-year lithium battery to protect your programmed data against main transmitter battery failure. If your system displays “error” or your data resets to the factory defaults, return your transmitter to Horizon Service Center (see page 93) for lithium battery replacement. CONTROL STICK LENGTH ADJUSTMENT To adjust stick length, use a 2mm Allen wrench to loosen the setscrew located inside the end of the stick.
RANGE TESTING ������������������ ������������������������������ Before each flying session, and especially with a new model, it is important to perform a range check. The DX6 incorporates a system which, when the bind button on the back of the transmitter is pressed, the output power reduces allowing for a range check. HOW TO RANGE TEST THE SYSTEM 1. With the model resting on the ground, stand 30 paces (approx. 90 feet) away from the model. 2.
BINDING ����������� ����������������� ����������������������������� ������� ������ Each Spektrum™ transmitter has a GUID (Globally Unique Identifier) code. Binding is the process of programming the receiver to recognize the GUID of a single specific transmitter. Binding teaches the receiver the specific GUID of that transmitter, so that the receiver will only listen to the information from its previously bound transmitter and ignores everything else.

CHAPTER 3: KEY INPUT AND DISPLAY Two input keys are located at the lower faceplate of the DX6 transmitter. The keys are used to access and program the transmitter.
CHAPTER 5: INPUT MODE AND FUNCTION NORMAL DISPLAY ������������������������ ��������������� ������������ � ��������������� When the power switch is turned on, the screen will read as shown in the diagram. This screen is referred to as the normal display. DIRECT TRIM ACCESS DISPLAY The Direct Trim function of the DX6 can be accessed through the use of any of the four digital trims levers (throttle, aileron, elevator, or rudder).
SYSTEM MODE To enter system mode, press the SCROLL and INCREASE buttons simultaneously upward while turning on the transmitter. You can now select any of 6 system mode functions shown here in the flow chart. Press the SCROLL button upward to move through the system mode functions. Information for each function is located on the page number listed next to the function name. To exit the system mode, press the SCROLL and INCREASE buttons upward simultaneously or turn off the transmitter.
FUNCTION MODE To enter the Function mode, turn on the transmitter. Press the SCROLL and CHANNEL buttons simultaneously upward until a beep is heard. The display will change accordingly and show the last active function. Press the Scroll button to scroll through the functions one by one as shown in the flowchart below. Once the appropriate function is selected, press the CHANNEL button downward to select the appropriate channel.
CHAPTER 6: FUNCTIONS (SYSTEM MODE) MODEL TYPE SELECTION Two types of aircraft programming are available with the DX6, airplane (AC) and helicopter (HE). When entering the model type selection function, the current model type will appear on the screen. (This will be the current model type set as the factory default or the last model used.) When you press the INCREASE or DECREASE button to change the model type, the new model type indicated on the screen will flash.
DATA RESET The data reset function allows you to reset all the programming in the current model selected (1–10) to the factory default settings. Before using the Data Reset function, it is important to enter the model selection function and select the desired model number (1–10) for which you want to reprogram to the factory settings. The model selection function is described on page 36.
DUAL RATE SWITCH SELECTION The dual rate switch position is selectable and the elevator and aileron dual rates can be combined on one switch. This allows a single switch to be used when moving from high rates to low rates. Exponential Rate (EXP) is also available for both aileron and elevator and works in conjunction with the dual rate function to provide reduced sensitivity movements around neutral while allowing maximum servo travel.
WING TYPE SELECTION Flaperon, V-tail, and Delta Mixing are available for aircraft that require these functions. The flaperon feature is used when two servos are located in the wing, one to control each aileron plus this function allows the ailerons to be drooped or raised while still functioning fully as ailerons. V-Tail Mixing combines rudder and elevator for V-Tail operations. The Delta Wing function allows the aileron to also act as the elevator, while retaining independent use of both functions.
WING TYPE SELECTION (CONTINUED) ��� �������� ������� ������������������������������ ���������������������������� ��������������������������� ���������������������������� ���������������������������� TO ACTIVATE FLAPERON (FPR) MIXING (WING TYPE MODE) 1. In System Setup mode, press the SCROLL button until “MIX WNG” appears on the screen. 2. Press the INCREASE button to activate Flaperon Mixing. V-TAIL V-Tail Mixing requires two servos, each connected to the right and left tail control surfaces.
WING TYPE SELECTION (CONTINUED) DELTA-WING MIXING Delta or Elevon Mixing is designed for flying wing type airplanes and employs two servos in the wing to control two trailing edge control surfaces for pitch and roll control. Elevator stick inputs will cause the two wing servos to function in conjunction with one another in the same direction to create an up/down movement of both surfaces to control pitch.
MODEL SELECTION The DX6 has memory for ten models. It can store the settings for ten airplanes, ten helicopters, or any combination of both types of models. ��������������������������� ����������������������������� ���������������������� ��������������������� ������������������������� ������������������ ACCESSING THE MODEL SELECTION FUNCTION 1. Press the SCROLL and INCREASE buttons upward simultaneously and hold. 2. Turn on the transmitter to enter the system mode. 3.
MODEL NAME ENTRY The DX6 allows a three-digit name to be input for each of the ten models available. The current model will be displayed in the normal display. This feature helps identify different aircraft types or model setups.
CHAPTER 7: FUNCTIONS (FUNCTION MODE) SERVO REVERSING Servo reversing is a convenient function used in the setup of a new aircraft. It is used to change the direction of servo rotation in relation to the corresponding stick movement. Servo reversing is available for all six channels.
DUAL RATE Different types of maneuvers require varying amounts of control movements. Snap rolls require large control movements, while smooth maneuvers like long slow rolls are best performed with smaller control movements. Dual rates allow you to change the control movements in flight at the flip of a switch. This allows you to execute maneuvers requiring both radical control movements and small control movements during a single flight. Dual rate is available for the aileron and elevator channels.
EXPONENTIAL Programmable exponential adjustments are offered on the aileron and elevator channels on the DX6 system. Exponential is a function that allows you to tailor the response rate of the controls as compared to the stick inputs. The purpose of exponential is to reduce the sensitivity in the middle portion of stick movement, while still allowing full travel at the end of the stick movement. The adjustable range of the Exponential function is from 0–100%.
SUB-TRIM Sub-trim is an electronic trim that is available for each of the six channels. Sub-trim is particularly useful to precisely neutralize the servo position electronically, when it difficult to achieve the desired position mechanically. Note: It is recommended to use as little Sub trim value as possible for adjustment.
TRAVEL ADJUSTMENT The amount of servo travel is adjustable in each direction independently for each of the six channels. The adjustment range is from 0% to 150%. Travel adjustment is factory set at 100% for all channels. The travel adjustment value direction displayed on the screen coincides with the position of the stick or switch (e.g., flap switch, gear switch). This function is useful to adjust control surface travel without the need for mechanical adjustment.
AILERON-TO-RUDDER MIXING On some types of aircraft, it is desirable to mix aileron and rudder to make coordinated turns. The DX6 allows the mixing of aileron-to-rudder and allows you to adjust the amount and direction of aileron to rudder mixing. The aileron-to-rudder mixing can be left on all the time or it can be turned off with the selection of one of three switches on page 32.

Press the CHANNEL button until “MIX ARS” appears on the screen. 2.
ELEVATOR-TO-FLAP MIXING Elevator-to-flap mixing in opposite directions (elevator up and flaps down) is commonly used to increase the pitch rate of an aircraft. This is commonly used in fun fly airplanes. Mixed in the same direction (elevator up, flaps up) it prevents tip stalling in high alpha maneuvers. This is very popular with 3D airplanes. This function can be always be left on, or turned off and on, via one of three selectable switches. See page 46 for more on Elevator-to-Flap mixing.

Press the CHANNEL button until “MIX EFS” appears on the screen. 2.
DIFFERENTIAL Aileron differential is used to correct roll to yaw coupling and adverse yaw characteristics during rolling maneuvers. In order to activate differential, the flaperon or Delta wing type must be selected in the system mode (see page 35). Also, each aileron control surface must have its own servo with the right aileron servo plugged into the aileron channel (#2) on the receiver and the left aileron servo plugged into the Flap Aux 1 channel (#6) on the receiver.
FLAP-TO-ELEVATOR OFFSET TRIM When the flaps are deployed, most airplanes exhibit pitching tendencies (most pitch nose up with down flap). Elevator offset trim is designed to prevent this pitching. Flap-to-elevator offset trim automatically changes the elevator trim to a preset value when the flap switch is activated. Note: Flap-to-elevator offset trim is also useful as a dual elevator trim even for airplanes without flaps.
PROGRAMMABLE MIXING (A, B, C) In airplane mode, the DX6 offers three programmable mixes (A, B, and C) allowing numerous mixing options. This function allows mixing any one channel to any other channel. The mix can remain ON at all times, or be switched ON/ OFF in flight using a number of different switches. Each channel is identified by channel numbers 1-6 (i.e., 2 = aileron, 4 = rudder, etc.). The channel appearing first is known as the “master channel,” or the channel to which you want to mix.

OFFSET MIXING OFFSET ADJUSTMENT The purpose of the mixing offset feature is to redefine the neutral position of the slave channel to be mixed. Any desired position may be selected for the offset reference point. To set the offset position, Place the master channel’s stick to the desired position and press either the INCREASE or DECREASE keys. This position is now stored in the memory and its offset value from the neutral position of the master channel is indicated numerically on the LCD display.
PROGRAMMING A RUDDER DUAL RATE Programmable mixing is a powerful feature that offers many creative options. As an example, a dual rate rudder can be easily added and turned on/ off via a selected switch. By mixing rudder-to-rudder, (4-4) selecting the desired switch to turn on/off the mix and by assigning positive values to increase the rudder travel, or negative values to reduce the travel a rudder dual rate is added that offers independent throw values in each direction.

SPEKTRUM DX6 • AIRCRAFT PROGRAMMING GUIDE
CHAPTER 1: TRANSMITTER CONTROLS DIGITAL TRIM LEVERS The DX6 features four digital trim levers with a direct trim display feature for ultra precise adjustments. When a trim input is given, the display screen will automatically change to show the trim value for current channel being adjusted. Once the trim change has been completed, the screen will automatically return to the previous screen display after 2–3 seconds.
LITHIUM BATTERY Note: The DX6 has a 5-year lithium battery to protect your programmed data against main transmitter battery failure. If your system displays “error” or your data resets to the factory defaults, return your transmitter to Horizon Service Center (see page 93) for lithium battery replacement. CONTROL STICK LENGTH ADJUSTMENT To adjust stick length, use a 2mm Allen wrench to loosen the setscrew located inside the end of the stick.
RANGE TESTING ������������������ ������������������������������ Before each flying session and especially with a new model, it is important to perform a range check. The DX6 incorporates a system which when the bind button on the back of the transmitter is pressed, the output power is reduced allowing for a range check. HOW TO RANGE TEST THE SYSTEM 1. With the model resting on the ground, stand 30 paces (approx. 90 feet) away from the model. 2.

The display will change accordingly and show the last active function. Press the SCROLL button to SCROLL through the functions one by one as shown in the flowchart below. Once the appropriate function is selected, press the CHANNEL button downward to select the appropriate channel.
CHAPTER 6: FUNCTIONS (SYSTEM MODE) MODEL TYPE SELECTION Two types of aircraft programming are available with the DX6, airplane (AC) and helicopter (HE). When entering the model type selection function, the current model type will appear on the screen. (This will be the current model type set as the factory default or the last model used.) When you press the INCREASE or DECREASE button to change the model type, the new model type indicated on the screen will flash.
DATA RESET The data reset function allows you to reset all the programming in the current model selected (1–10) to the factory default settings. Before using the Data Reset function, it is important to enter the model selection function and select the desired model number (1–10) for which you want to reprogram to the factory settings. The model selection function is described on page 70.
DUAL RATE SWITCH SELECTION The dual rate switch position is selectable and the elevator and aileron dual rates can be combined on one switch. This allows a single switch to be used when moving from high rates to low rates. Exponential Rate (EXP) is also available for both aileron and elevator and works in conjunction with the dual rate function to provide reduced sensitivity movements around neutral while allowing maximum servo travel.
GEAR/GYRO SWITCH SELECTION The DX6 gear/gyro switch selection function enables the dual rate values of the gyro to be combined with one of four switches (flight mode, throttle hold, aileron dual rate, elevator dual rate). This feature is for use with gyros that offer a dual rate sensitivity adjustments.. The most common use for this feature would be to combine the gyro dual rate adjustment with the flight mode switch.
MODEL SELECTION The DX6 has memory for ten models. It can store the settings for ten airplanes, ten helicopters, or any combination of both types of models. ��������������������������� ����������������������������� ���������������������� ��������������������� ������������������������� ������������������ ACCESSING THE MODEL SELECTION FUNCTION 1. Press the SCROLL and INCREASE buttons upward simultaneously and hold. 2. Turn on the transmitter to enter the system mode. 3.
MODEL NAME ENTRY The DX6 allows a three-digit name to be input for each of the ten models available. The current model will be displayed in the normal display. This feature helps identify different aircraft types or model setups.
CHAPTER 7: Function Mode SERVO REVERSING Servo reversing is a convenient function used in the setup of a new aircraft. It is used to change the direction of servo rotation in relation to the corresponding stick movement. Servo reversing is available for all six channels.
DUAL RATE Dual rate is available for the aileron and elevator channels. The purpose of this function is to allow for in-flight selection of two preset servo travels for each of these channels. The amount of travel is adjustable from 0-125%. The factory settings for both switch positions (0 and 1) are 100%. Either position may be selected as the low or high rate by placing the switches in the desired position and adjusting the value for that position. Operation of these switches is described on page 68.
EXPONENTIAL Programmable exponential adjustments are offered on the aileron and elevator channels on the DX6 system. Exponential is a function that allows you to tailor the response rate of the controls as compared to the stick inputs. The purpose of exponential is to reduce the sensitivity in the middle portion of stick movement, while still allowing full travel at the end of the stick movement. The adjustable range of the Exponential function is from 0–100%.
SUB-TRIM Sub-trim is an electronic trim that is available for each of the six channels. Sub-trim is particularly useful to precisely neutralize the servo position electronically, when it difficult to achieve the desired position mechanically. Note: It is recommended to use minimal sub trim values as possible for adjustment. If more that 20–30 points are required, it is suggested that a mechanical linkage adjustment be performed at the servo by rotating the servo horn on the spline and adjusting the linkage.
TRAVEL ADJUSTMENT The amount of servo travel is adjustable in each direction independently for each of the six channels. The adjustment range is from 0% to 150%. Travel adjustment is factory set at 100% for all channels. The travel adjustment value direction displayed on the screen coincides with the position of the stick or switch (e.g., flap switch, gear switch). This function is useful to adjust control surface travel without the need for mechanical adjustment.
THROTTLE HOLD The throttle hold function enables the throttle to be held in a specific location, while allowing the remaining channels to function normally. The purpose of this function is for autorotation landings, however, many pilots find throttle hold useful as an arming switch for electric helicopters to prevent the motor from accidentally running if the sticks or switches are bumped, or in the wrong position.
PITCH CURVE The DX6 offers three independent pitch curves with three adjustable points per curve. This function allocates a separate pitch curve setting during Normal, Stunt, and Throttle Hold modes to maximize flight performance. Once the pitch curves are established, each can be activated in flight using the two-position flight mode switch and the throttle hold switch. Each of the three points on the pitch curve is independently adjustable from 0–100%.
ACCESSING THE PITCH CURVE FUNCTION 1. Turn on the transmitter. 2. Press the SCROLL and INCREASE buttons simultaneously to enter the Function mode. 3. Press the SCROLL button until “PLN” appears on the screen. The letter to the far right indicates the specific pitch curve section that you are in (N, S or H). The letter in the center indicates the point that is selected. 4. Press the CHANNEL button to select the pitch point of the pitch curve you want to change. 5.
THROTTLE CURVE Adjustment of the throttle curve is very similar to the pitch curve adjustment described in the preceding section. Two throttle curves are available—normal and stunt. The normal or hover throttle curve has three points (L,2, H) and the stunt or flight throttle curve has two points (L and 2). The two throttle curves are activated by the flight mode switch located on the top left rear corner of the transmitter.
ACCESSING THE THROTTLE CURVE FUNCTION 1. Turn on the transmitter. 2. Press the SCROLL and INCREASE buttons simultaneously to enter the function mode. 3. Press the SCROLL button until “TLN” appears on the screen. The letter to the far right indicates the specific throttle curve mode that you are in (N, S, or H). The letter in the center indicates the throttle point that you can adjust. 4. Press the CHANNEL button to select the throttle point of the throttle position that you have selected (L, 2, or H). 5.
REVOLUTION MIXING Revolution Mixing is only used with conventional (non-heading hold) gyros. The Revolution Mixing function combines tail rotor input with the throttle/collective function to counteract the torque created by the engine. When properly adjusted, the helicopter will climb and descend without a tendency to yaw in either direction. Revolution mixing is for use with non-heading lock gyros only.
PROGRAMMABLE MIXING (A) The DX6 in Helicopter mode offers one (1) programmable mix to be used for a number of different purposes. The functions allow mixing any one channel to any other channel. The mix can remain on at all times or be switched off in flight using a number of different switches. Each channel is identified by channel numbers 1-6 (i.e., 2 = aileron, 4 = rudder, etc. The channel appearing first is known as the Master channel or the channel to which you want to mix.

Any desired position may be selected for the offset reference point. To set the offset position, Place the master channel’s stick to the desired position and press either the INCREASE or DECREASE keys. This position is now stored in the memory and its offset value from the neutral position of the master channel is indicated numerically on the LCD display.
PROGRAMMING A RUDDER DUAL RATE Programmable mixing is a powerful feature that offers many creative options. As an example a dual rate rudder can be easily added and turned on/ off via a selected switch. By mixing rudder to rudder, (4-4) selecting the desired switch to turn on/off the mix and by assigning positive values to increase the rudder travel, or negative values to reduce the travel, a rudder dual rate is added that offers independent throw values in each direction.
CCPM SWASHPLATE MIXING CCPM (Cyclic Collective Pitch Mixing) mixing is used for helicopters that utilize a 120° CCPM swashplate control system. CCPM is a type of mixing where three servos are connected to the swashplate and operate in unison and independently to control pitch and cyclic inputs. Refer to the diagram below for proper 120° Three Servo-CCPM identification and connection.

CCPM SERVO LOCATIONS The 120° CCPM system requires the use of three servos to operate, Aileron, Elevator, and AUX 1 (Pitch). The labeling of these servos can become quite confusing because with the CCPM function, the three servos no longer work independently, but rather as a team, and their functions are now combined. For this reason, we will refer to the three servos in the following manner: Aileron Servo: We will refer to this servo as the “Left” servo. The channel number for this servo is CH2.
CCPM SERVO CONNECTIONS HOW 120 CCPM WORKS 120° Three-Servo CCPM relies on the radio’s special programming rather than a mechanical mixer to operate the swashplate to achieve pitch and cyclic control. The radio’s 120° Three-Servo CCPM function automatically mixes the three servos to provide the correct mixing inputs for aileron (roll), elevator (fore and aft pitch), and collective pitch. The following is an example of how each control input affects the servo’s movement: 1.
