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.

With 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.

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.

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.

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.

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).

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).
4. If control issues exist, call the Horizon Product Support Team at 1-877-504-0233 for further assistance.

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

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.

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.

The AR6200 features the SmartSafe™ fail-safe system.
SMARTSAFE:
• Prevents unintentional electric motor response on start-up.
• Eliminates the possibility of over-driving servos on start-up.
• Establishes low-throttle fail safe if the RF signal is lost.
• Maintains last-commanded control surface position in the event of RF link interruption.
: Fail-safe positions are stored via the stick and switch positions on the transmitter
during binding.

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.

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.

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.

With all radio installations, it is vital the onboard power system provides adequate power without interruption
to the receiver even when the system is fully loaded (servos at maximum flight loads). This becomes especially
critical with giant-scale models that utilize multiple high torque/ high current servos. Inadequate power systems
that are unable to provide the necessary minimum voltage to the receiver during flight loads have become the
number-one cause of in-flight failures. Some of the power system components that affect the ability to properly
deliver adequate power include: the selected receiver battery pack (number of cells, capacity, cell type, state of
charge), switch harness, battery leads, regulator (if used), power bus (if used).
While Spektrum’s receivers’ minimum operational voltage is 3.5 volts, it is highly recommended the system
be tested per the guidelines below to a minimum acceptable voltage of 4.8 volts during ground testing. This
will provide head room to compensate for battery discharging or if the actual flight loads are greater than the
ground test loads.

1. When setting up large or complex aircraft with multiple high torque servos, it’s highly recommend that
a current and volt-meter (Hangar 9 HAN172) be used. Plug the volt-meter in an open channel port in
the receiver and, with the system on, load the control surfaces (apply pressure with your hand) while
monitoring the voltage at the receiver. The voltage should remain above 4.8 volts even when all servos
are heavily loaded.
: The optional Flight Log has a built-in volt meter and it can be used to perform this test.
2. With the current meter in line with the receiver battery lead, load the control surfaces (apply pressure
with your hand) while monitoring the current. The maximum continuous recommended current for a
single heavy-duty servo/battery lead is three amps while short-duration current spikes of up to five
amps are acceptable. Consequently, if your system draws more than three amps continuous or five
amps for short durations, a single battery pack with a single switch harness plugged into the receiver for
power will be inadequate. It will be necessary to use multiple packs with multiple switches and multiple
leads plugged into the receiver.
: The Flight log can not measure current draw. Please note that if the flight log is used to
measure voltage, the HAN172 current meter still must be used to measure the draw of the servos.
3. If using a regulator, it’s important the above tests are done for an extended period of 5 minutes. When
current passes through a regulator, heat is generated. This heat causes the regulator to increase
resistance, which in turn causes even more heat to build up (thermal runaway). While a regulator may
provide adequate power for a short duration, it’s important to test its ability over time as the regulator
may not be able to maintain voltage at significant power levels.
4. For really large aircraft or complex models (for example 35% and larger or jets) multiple battery packs
with multiple switch harnesses are necessary or in many cases one of the commercially available power
boxes/ busses is recommended. No matter what power systems you choose, always carry out test #1
above making sure that the receiver is constantly provided with 4.8 volts or more under all conditions.
5. The latest generation of Nickel Metal Hydride batteries incorporate a new chemistry mandated to be
more environmentally friendly. These batteries, when charged with peak detection fast chargers, have
tendencies to false peak (not fully charge) repeatedly. These include all brands of NiMH batteries. If
using NiMH packs be especially cautious when charging making absolutely sure that the battery is fully
charged. It is recommended to use a charger that can display total charge capacity. Note the number of
mAh put into a discharged pack to verify it has been charged to full capacity.

4. Q: Sometimes my receiver loses its bind and won’t connect, requiring rebinding. What happens if the
bind is lost in flight?
A: The receiver will never lose its bind unless it’s instructed to. It’s important to understand that during
the binding process the receiver not only learns the GUID (code) of the transmitter but the transmitter
learns and stores the type of receiver that it’s bound to. If the trainer switch is pulled on the transmitter
at any time and the transmitter is turned on, the transmitter looks for the binding protocol signal from
a receiver. If no signal is present, the transmitter no longer has the correct information to connect to a
specific receiver and in essence the transmitter has been “unbound” from the receiver. We’ve had several
customers using transmitter stands or trays that unknowingly depress the bind button and the system is
then turned on, losing the necessary information to allow the connection to take place. We’ve also had
customers that didn’t fully understand the range test process and pull the trainer switch before turning
on the transmitter, also causing the system to “lose its bind.” If the system fails to connect, one of the
following has occurred:
• The wrong model has been selected in the model memory (ModelMatch).
• The transmitter is near conductive material (transmitter case, truck bed, etc.) and the reected 2.4GHz
energy is preventing the system from connecting. (See #2 above)
• The trainer switch was pulled and the radio was turned on unknowingly (or knowingly) previously,
causing the transmitter to no longer recognize the receiver.

Your DSM2 equipped 2.4GHz system is intuitive to operate, functioning nearly identically to 72MHz systems.
Following are a few common questions from customers:
1. Q: Which do I turn on first, the transmitter or the receiver?
A: It doesn’t matter, if the receiver is turned on first-the throttle channel doesn’t put out a pulse position
at this time, preventing the arming of electronic speed controllers, or in the case of an engine powered
aircraft, the throttle servo remains in its current position. When the transmitter is then turned on
the transmitter scans the 2.4GHz band and acquires two open channels. Then the receiver that was
previously bound to the transmitter scans the band and finds the GUID (Globally Unique Identifier code)
stored during binding. The system then connects and operates normally. If the transmitter is turned
on first, the transmitter scans the 2.4GHz band and acquires two open channels. When the receiver
is turned on, the receiver scans the 2.4GHz band looking for the previously stored GUID, and when it
locates the specific GUID code and confirms uncorrupted repeatable packet information, the system
connects and normal operation takes place. Typically this takes 2 to 6 seconds.
2. Q: Sometimes the system takes longer to connect and sometimes it doesn’t connect at all. Why?
A In order for the system to connect (after the receiver is bound) the receiver must receive a large number
of continuous (one after the other) uninterrupted perfect packets from the transmitter in order to connect.
This process is purposely critical of the environment ensuring that it’s safe to fly when the system does
connect. If the transmitter is too close to the receiver (less that 4 feet) or if the transmitter is located near
metal objects (metal transmitter case, the bed of a truck, the top of a metal work bench, etc.) connection
will take longer and in some cases connection will not occur as the system is receiving reflected 2.4GHz
energy from itself and is interpreting this as unfriendly noise. Moving the system away from metal
objects or moving the transmitter away from the receiver and powering the system up again will cause
a connection to occur. This only happens during the initial connection. Once connected the system
is locked, and should a loss of signal occur (fail-safe), the system connects immediately (4ms) when
signal is regained.
3. Q: I’ve heard that the DSM system is less tolerant of low voltage. Is this correct?
A: All DSM receivers have an operational voltage range of 3.5 to 9 volts. With most systems this is not a
problem as in fact most servos cease to operate at around 3.8 volts. When using multiply high current
draw servos with a single or inadequate battery/ power source, heavy momentary loads can cause the
voltage to dip below this 3.5 volt threshold thus causing the entire system (servos and receiver) to
brown out. When the voltage drops below the low voltage threshold (3.5 volts), the DSM receiver must
reboot (go through the start up process of scanning the band and finding the transmitter) and this can
take several seconds.
: Receivers manufactured after July of 2007 offer a quick connect feature that reconnect
immediately when recovering from a low voltage “brown out.”
Please read the receiver power requirement on page 21 as this explains how to test for and prevent
this occurrence.
