Spektrum’s DX6i 6-channel radio system offers advanced programming features normally only available in
sophisticated radio systems. The DX6i incorporates 2.4GHz DSM2™technology, offering full “beyond the limits
of sight” range ideal for all types and sizes of electric, gas, and glow-powered aircraft. No longer will you have to
wait for a frequency pin or be concerned that someone may inadvertently turn on to your same frequency. With
Spektrum™DSM2 technology, when you’re ready to fly any aircraft—from parkflyers and helicopters to giant-
scale—simply turn on, and go flying!

Your DX6i transmits on the 2.4GHz band and utilizes DSM2 second-generation Digital Spread Spectrum
Modulation offering beyond visual range in all types and sizes of aircraft. Unlike conventional narrow
band systems, Spektrum’s 2.4GHz digital DuaLink™technology is virtually immune to internal and external
radio interference.
Included with your DX6i is an AR6200 6-channel receiver. The AR6200 combines an internal and external receiver,
offering superior path diversity. The DX6i transmitter simultaneously transmits on two frequencies, creating dual
RF paths. This dual path redundancy, plus the fact that each of the two receivers is located in a slightly different
location exposes each to a different RF environment and creates a bulletproof RF link in all conditions.
.0%&-."5$)
With patented ModelMatch™ technology, you’ll never mistakenly attempt to fly your model using the wrong
memory again. The DX6i features ModelMatch technology that prevents the operation of a model if the wrong
model memory is selected. During binding, the receiver actually learns and remembers the specific model memory
(1 of 10) that the transmitter is currently programmed to. Later, if the incorrect model is selected in the transmitter
and the receiver is turned on, the model simply won’t operate, preventing a possible crash. Change programming
to the matching model memory and you are set to fly.

You’ll be glad to know the DX6i is compatible with all current Spektrum and JR brands of DSM aircraft receivers.
However when using the DX6i with one of the Spektrum parkflyer receivers, like the AR6000, AR6100, AR6100E,
AR6300, etc., it’s imperative that these receivers be limited to flying parkflyer-type aircraft and mini and micro
helicopters only.

DX6i systems that are included in some Ready-To-Fly aircraft (like the E-flite Blade 400) require 4 AA batteries
while DX6i systems purchased separately include rechargeable NiMH batteries and an overnight charger.
*/45"--*/(5)&#"55&3*&4
For transmitters that require 4 AA batteries:
Remove the battery door and install 4 AA batteries, noting the polarity of each corresponds with the diagram in the
battery holder. Replace the battery door.
/PUF: Optional NiCd or NiMH 1.2 volt AA rechargeable batteries can also be used. A charge jack
is located on the left side of the transmitter for convenient recharging.

Several versions of the DX6i include rechargeable NiMH batteries and a 4.8-volt charger. It is imperative that you
fully charge the transmitter. To do so, using the included wall charger, leave the charger and batteries connected
overnight.
The charger supplied with this system is designed to recharge your transmitter batteries at a rate of 150mA.
Do not use this charger for equipment other than Spektrum. The charging plug polarity may not be the same
and equipment damage can result. During the charging operation, the charger’s temperature is slightly elevated.
This is normal.

A charging jack is located on the left side of the transmitter. If rechargeable batteries are used they can be
conveniently charged without removing them from the transmitter using the charge jack. IMPORTANT: All
Spektrum charge jacks are center pin negative. This is the opposite of many chargers. Before using a charger,
make sure the connector is center pin negative. This can be done using a voltmeter. Also, unlike conventional
radio systems that use 8 cells to power the transmitter, the DX6i uses 4 cells. This is due to the electronics being
more efficient. When charging, be sure to use a charger designed for 4 cells (4.8-volt battery pack) when charging
the transmitter.
53"/4.*55&310-"3*5:
The center pin on all Spektrum transmitters is negative. Therefore, the center pin on all Spektrum chargers is
negative, not positive. This is different from many other manufacturers’ chargers and radio systems. Beware of
improper connections based on “color coded” wire leads, as they may not apply in this instance. You must make
sure that the center pin of your Spektrum transmitter is always connected to the negative voltage of your charger
for correct polarity hookup.

The DX6i employs digital trim levers on aileron, elevator, throttle, and rudder. The ADT (Advanced Digital Trim)
feature is designed to automatically store the selected trim values for each model. When a different model is
selected, the previously stored trim positions for that model are automatically returned to their previous settings.
Visual trim positions are displayed on the main screen. The trims feature dual speed scrolling. Holding the trim

The AR6200 incorporates dual receivers, offering the security of dual path RF redundancy. An internal
receiver is located on the main PC board, while a second remote receiver is attached to the main board with
a 6-inch extension. By locating these receivers in slightly different locations in the aircraft, each receiver is
exposed to its own RF environment, greatly improving path diversity (the ability for the receiver to see the
signal in all conditions).

Install the main receiver using the same method you would use to install a conventional receiver in your aircraft.
Typically, wrap the main receiver in protective foam and fasten it in place using rubber bands or Velcro straps.
Alternately, in electric models or helicopters, it’s acceptable to use thick double-sided foam tape to fasten the main
receiver in place.
Mounting the remote receiver in a slightly different location, even just inches away from the primary receiver,
gives tremendous improvements in path diversity. Essentially, each receiver sees a different RF environment and
this is key to maintaining a solid RF link, even in aircraft that have substantial conductive materials (i.e. larger gas
engines, carbon fiber, pipes, etc.), which can attenuate the signal.
Using servo tape, mount the remote receiver keeping the remote antennas at least 2 inches (51mm) away from the
primary antenna. Ideally, the antennas will be oriented perpendicularly to each other, however, we’ve found this to
not be critical. In airplanes, we’ve found it best to mount the primary receiver in the center of the fuselage on the
servo tray and to mount the remote receiver to the side of the fuselage or in the turtle deck.
In helicopters, there is generally enough room on the servo tray to achieve the necessary separation. If necessary,
a mount can be fashioned using clear plastic to mount the external receiver.

In gas- and glow-powered aircraft where vibration is present, the servos should be mounted using the supplied
rubber grommets and bushings. Do not over-tighten the mounting screws. The diagram will assist you in properly
mounting the grommets and bushings. In electric and non-powered aircraft, there are many acceptable methods
for mounting the servo, including servo tape and even glue. See the information included with your aircraft for the
recommendation for installing servo(s) in your aircraft.

Before each flying session, and especially with a new model, it is important to perform a range check. The DX6i
incorporates a range testing system which, when placed in the RANGE CHECK program and the trainer switch is
activated and held, reduces the output power, allowing a range check.

1. With the model resting on the ground, stand 30 paces (approx. 90 feet) away from the model.
2. Face the model with the transmitter in your normal flying position. Place the transmitter in the range test
screen (see page 51 or 98) and pull and hold the trainer switch on the top of the transmitter. This causes
reduced power output from the transmitter.
3. You should have total control of the model with the trainer switch pulled at 30 paces (90 feet).

The AR6200 receiver must be bound to the transmitter before it will operate. Binding is the process of teaching the
receiver the specific code of the transmitter so it will connect to that specific transmitter. Once bound, the receiver
will only connect to the transmitter when the previously bound model memory is selected. If another model
memory is selected, the receiver will not connect. This feature is called ModelMatch™and prevents flying a model
using the wrong model memory.
1. With the system hooked up as shown, insert the bind plug in the charge plug receptacle.
2. Turn on the receiver switch (not included). Note that the LEDs on both receivers should be flashing,
indicating that the receiver is ready to bind.

3. Establish the desired fail-safe stick positions: normally low throttle and flight controls neutral.
4. Pull and hold the trainer switch on the top of the transmitter while turning on the power switch. Within
a few seconds the system should connect. The LEDs on the receivers should go solid, indicating the
system has connected.
5. Remove the bind plug from the charge jack before turning off the receiver and store it in a
convenient place.
6. After you’ve programmed your model, it’s important to rebind the system so the true low throttle and
neutral control surface positions are programmed.

Smartsafe is ideal for most types of electric aircraft and is also recommended for most types of gas- and glow-
powered airplanes and helicopters. Here’s how SmartSafe works.
3&$&*7&3108&30/-:
When the receiver only is turned on (no transmitter signal is present), the throttle channel has no output, to avoid
operating or arming the electronic speed control. In glow-powered models, the throttle servo has no input so it
remains in its current position.
"'5&3$0//&$5*0/
When the transmitter is turned on, and after the receiver connects to the transmitter, normal control of all channels
occurs. After the system makes a connection, if loss of signal occurs, SmartSafe drives the throttle servo only to its
preset fail-safe position (low throttle) that was set during binding. All other channels hold their last position. When
the signal is regained, the system immediately (less than 4 ms) regains control.
