SPEKTRUM DX6i • RADIO INSTRUCTION MANUAL

When you bind your transmitter to a Spektrum receiver, you 
program the receiver with Failsafe defaults. If the receiver loses 
connection to the transmitter, the receiver goes to Failsafe, 
operating in default control positions programmed at binding 
(until connection is restored to the transmitter). 
 
NOTICE: Failsafe varies among receivers. Before using a 
receiver, read receiver’s instructions for Failsafe instructions and 
information.

SmartSafe Failsafe, Hold Last Command Failsafe and  
Pre-Connect Failsafe are set at binding. 
These Failsafes can provide these benefits:

• When only the receiver is powered on (no transmitter signal 

is present), speed controller (ESC) does not arm and electric 
motor is not powered on.

• If connection is lost, SmartSafe moves throttle to position set 

at binding so electric motors power off or gas/glow engines 
decrease to idle.

• If connection is lost, all channels (except for throttle channel) 

hold the last command received from the transmitter. For 

example, if the model is turning when the control connection 
is lost, the model will keep turning until connection to the 
transmitter returns.

 

CAUTION: Restrain model on the ground while binding 

the receiver to a transmitter (which is setting Failsafe) 

or doing a test of Failsafe. When Failsafe is not set correctly, a 
model’s throttle may go to middle or full throttle.

1. Keep bind plug in receiver bind port during binding. 
2. Remove bind plug only after receiver connects to transmitter. 

Note: This test applies only to receivers with these features.

1. Power on receiver and make sure model responds with 

throttle going to lowest setting. 

2. Power on transmitter and wait for connection to the receiver. 
3. Increase transmitter throttle then power off the transmitter. 
4. Make sure model throttle goes to low setting and that all 

controls hold the last command. 

NOTICE: Before flying, ALWAYS make sure the transmitter and 
receiver are bound for the correct failsafe. 

Note: Not all Spektrum receivers have Preset Failsafe.  
Refer to your receiver’s instructions for Failsafe instructions  
and information. 
Preset Failsafe is useful for sailplanes. If there is a loss of signal, 
spoilers can deploy to bring the model down, preventing flyaway. 

CAUTION: Restrain model on the ground while binding 
the receiver to a transmitter (which is setting Failsafe) 

or doing a test of Failsafe. When Failsafe is not set correctly, a 
model’s throttle may go to middle or full throttle.

1. Install the bind plug in the receiver bind port. 
2. Power on the receiver. 
3. Receiver LED will blink, indicating the receiver is  

in bind mode. 

4. Remove the bind plug from the receiver. 
5. Receiver LED will continue blinking. 

6. Move transmitter control sticks and switches to desired 

failsafe positions (throttle to low position). 

7. Move and hold transmitter bind switch in bind position. 
8. Power on the transmitter. 
9. The receiver and transmitter connect in less  

than 15 seconds. 

10. When the receiver connects to the transmitter, the receiver 

LED will show a solid light, indicating bind. 

11. Release the transmitter bind switch. 
12. Remove bind plug from the receiver.

 

1. Power on transmitter and wait 5 seconds. 
2. Power on receiver. 
3. After receiver connects to transmitter, increase transmitter 

throttle then power off the transmitter. 

4. Make sure model throttle goes to low setting and that all 

controls go to preset positions.  

Note: Some analog servos may coast a small amount, even 
without a signal. This is normal.

Where supplied with the transmitter, install the primary receiver 
in your model. Put the primary receiver in protective foam and 
install the receiver in the model using rubber bands or hook-
and-loop straps. Use thick double-sided foam tape to install the 
primary receiver in electric models or helicopters. 

Install the remote receiver apart from the primary receiver to 
improve RF path diversity (a receiver’s ability to detect a signal in 

all conditions). Each receiver needs a different RF environment, 
especially in aircraft containing conductive materials (such as 
large gas engines, carbon fiber, pipes, etc.) which block a radio 
signal.

Install the remote receiver in the model using servo tape. Keep 
primary and remote receiver antennas at least 2 inches (51mm) 
apart. Move antennas so the wires are perpendicular to each 
other, although this is not critical.
