This crib sheet for the Spektrum DX6i covers the basic functions and operation of this transmitter.

Basic operation

Turning on and off

The on/ off switch is on the front of the radio. Ensure that all the switches are pushed back (away from you). Turning the radio off saves the settings to non-volatile memory; the batteries can be removed safely without losing the model's settings.

LCD display

When not displaying menu options, the LCD display shows the position of all the electronic trims, the current model memory number and name, the battery voltage, and the value of the countdown/ count up flight timer.

Navigating the menus

The menu system is accessed by pressing on the scroll wheel on the right front of the radio. The cursor or value is moved or changed by rolling the scroll wheel, and the option accepted by depressing the scroll wheel.
There are two levels to the menu system, called the "Adjust List" and the "Setup List"; they can be switched between by using the last menu item on each menu list. To return to the default display, scroll all the way up until "Main" is highlighted in the upper right corner.
Once a menu item has been activated, you can return to the menu lists by scrolling up (left) until "List" is highlighted.

Binding a receiver

Note: Binding a receiver to a transmitter also sets the failsafe values used should the radio link fail or fade. It is common to rebind to reset the failsafe values once the transmitter has been properly set up for the helicopter.
Select the appropriate model memory and switch the transmitter off.
Set the transmitter controls (especially throttle) to their failsafe positions.
Insert the bind plug into the battery/bind channel on the receiver. Plug in the receiver battery.
Holding up the trainer switch on the transmitter, turn on the transmitter power and wait for the receiver lights to stop flashing. Release the trainer switch
You should now have basic control over any servos plugged into the receiver.
Switch the receiver and transmitter off; remove the bind plug from the transmitter.

Adjust List menus

  • Model Select
Allows you to select the desired model memory. Use the scroll wheel until the desired memory number and name is shown, then press the scroll wheel to make those settings active.
  • D/R&Expo
Allows dual rates and exponential values to be set for cyclic and rudder controls.
Different rate and expo values can be set for both dual rate switch position for each control. To change the dual rate or expo value for a given dual rate switch position, flick the switch to the position to adjust, and then select the appropriate value with the scroll wheel, roll the scroll wheel to select the desired value, and the press the scroll wheel again to store the value.
The first value on each row is the dual rate factor to use, and can vary from 0% (no travel at all) to 100% (full/ normal travel). The second value is the exponential and ranges from -100% (extremely sensitive around centre) to +100% (extremely insensitive around centre).
  • Travel Adj
Allows the servo travel of each servo channel to be set, either side of centre.
To adjust a value, highlight the value with the scroll wheel, and depress the scroll wheel. Hold the control that normally corresponds that channel over to the side you wish to adjust, and use the scroll wheel to adjust the value. Push the control over to the other side to adjust the travel on the other side. Finally, depress the scroll wheel to commit the values.
  • Sub trim
Set the servo centre position to be moved, for each servo channel by changing the sub trim.
Use the scroll wheel to select the appropriate servo, depress the scroll wheel and roll the scroll wheel to select the new value, from (up) 100 to (down) 100. Depress the scroll wheel to save the new value.
  • Gyro
Allows a number of settings to do with gyro control to be set.
  • SW
Sets how the gyro gain value is changed: either SW-INH (off), SW-GYRO (changed by gyro (flap) switch), or SW-F.MODE (changed with flight mode switch).
  • RATE
The two rate values set the gyro gain channel value (and so the gyro gain) to use for each switch position. The value ranges from 0% (100% rate mode or heading hold), through 50% (servo mid position, gyro off), to 100% (full heading hold or rate mode). Useful values will tend to be around 25% and 75%.
  • THRO CURVE
Sets the throttle curve; the amount of thottle to use for each collective stick position.
Three 'curves' are provided. The first two, NORM and STUNT, are true 5-point curves; the final one HOLD is for throttle hold and provides a single value for setting an appropriate engine idle.
Scroll to the desired curve name, depress the scroll wheel, select the position to adjust (L, 2, 3, 4, H) (omitted if setting HOLD value), depress the scroll wheel, and then scroll to select the desired value. Depress the scroll wheel to set the current value.
The graph shows the shape of the current throttle curve, with a higher curve meaning more throttle. The point currently being adjusted is shown with a dotted line. The current collective stick position is shown with a heavy vertical line.
  • PITC CURVE
Sets the pitch curve; the amount of collective pitch to use for each collective stick position.
This menu is essentially the same as the throttle curve menu, except that throttle hold has its own true curve.
This menu is enabled if 120-degree swashplate mixing has been selected (see later).
It allows the amount and direction of the cyclic and collective controls to be set. Values range from -125% to +125%.
  • MIX 1, MIX 2
Allows two programmable mixes to be set. Changing the INH to ACT (and press the scroll wheel to set) enables and shows the mix settings.
The first channel is the master (from) channel, the second channel is the slave (to) channel. The rates are the rate to add (+) or subtract (-) to or from the slave channel as the master channel is changed away from centre. SW specifies when the mix is enabled, and can be ON (always on), F.MODE (idle up), GYRO (on gyro switch), AIL D/R or ELE D/R (on aileron or elevator dual rate switch). TRIM specifies whether master channel trim is considered for input.
To disable the mix, change ACT to INH.
  • REVO MIX
Revo mix allows a revolution mix to be specified for both normal mode and idle up. Unless you are using a rate mode gyro, you will want these values to be 0%.

Setup list

  • MODEL TYPE
Allows the model type of ACRO (airplane) or HELI (helicopter) to be selected. ACRO mode is beyond the scope of this guide.
  • MODEL NAME
Allows and 8-character name to be given to the current model.
  • MONITOR
Allows the commanded positions sent to the servos to be viewed graphically.
  • REVERSE
Allows the reversing of the servo channels individually. When setting up a CCPM helicopter, use this menu to get the servos moving together on collective inputs first.
  • SWASH TYPE
Allows you to select 1SERVO90 (mechanically mixed) or CCPM 120 (electronically mixed) swashplate types. If you have 3 servos equally spaced around the swashplate, you need the latter type.
  • THRO CUT
Enables and disables the throttle cut button. When enabled, it should be set to reduce the throttle sufficiently to stop a running internal combustion engine.
  • D/R COMBI
Allows tethering elevator, aileron, and rudder dual rates (and expo) to one switch rather than having each one controlled from their respective switches.
  • TIMER
Allows a timer to be set. Options are DOWN to set a countdown timer (useful for limiting flights so you do not overdischarge your lipos) or UP, the time (for the countdown timer), and SWITCH to set the switch that starts the timer: can be TRAINER, THR CUT or INHIBIT (off).
  • RANGE CHECK
Reduces transmitted radio power in order to do a range check. With range check running you should be able to get 30 paces away from your model while still having full control of your model.
  • POWER SETTING
Sets the output radio power for your location. Options are A-EU 328 and B-US 247. The EU limits output power to 100mW, where as the limit in the US is 200mW.
  • CONTRAST
Allows display contrast to be changed.
  • COPY/RESET
Allows the current model to be copied to another model memory, or the current model reset to default (generally useless) values.
