Problem
Possible Cause
Solution
Aircraft will not bind (during
binding) to transmitter
Transmitter too near aircraft during binding
process
Move powered transmitter a few feet from
aircraft, disconnect and reconnect flight
battery to aircraft
Aircraft or transmitter is too close to large metal
object
Move the aircraft or transmitter away from the
large metal object
The bind plug is not installed correctly in the
bind port
Install bind plug in bind port and bind the
aircraft to the transmitter
Flight battery/Transmitter battery charge is
too low
Replace/recharge batteries
Transmitter is a NX8 EU version and receiver is
DSM2
The NX8 EU version is not compatible with
DSM2 receivers
Aircraft will not link (after
binding) to transmitter
Transmitter too near aircraft during linking
process
Move powered transmitter a few feet from
aircraft, disconnect and reconnect flight
battery to aircraft
Aircraft or transmitter is too close to large metal
object
Move the aircraft or transmitter away from the
large metal object
Bind plug left installed in bind port
Rebind transmitter to the aircraft and remove
the bind plug before cycling power
Aircraft bound to different model memory
(ModelMatch™ radios only)
Select correct model memory on transmitter
Flight battery/Transmitter battery charge is
too low
Replace/recharge batteries
Transmitter may have been bound using different
DSM protocol
Bind aircraft to transmitter
Damaged remote receiver or receiver extension.
Required remote receiver is not connected
The receiver goes into failsafe
mode a short distance away from
the transmitter
Check the receiver antenna to be sure it is not
cut or damaged
Replace or contact Horizon Product Support
Main and remote receivers too near each other
Install main and remote receivers at least 2
inches (51mm) apart
Receiver quits
responding during operation
Low battery voltage
Completely recharge flight battery
Loose or damaged wires or connectors between
battery and receiver
Do a check of the wires and connection
between battery and receiver. Repair or
replace wires and/or connectors
Receiver loses its bind
Bind button pressed before transmitter powered on
Rebind by performing binding instructions
Receiver slowly blinking at
landing (DSM2 Only)
Loss of power to the receiver during flight
Check battery voltage
System powered on and connected, then
receiver powered off without powering off
transmitter
Power off transmitter when receiver is
powered off
Flight log registers undesirable
number of fades, losses or holds
or aircraft responds irregularly to
controls
Poor signal reception
Reposition remote receivers for improved RF
signal path diversity
Electronic feedback
Check for and stop feedback from servos or
motor systems to the ESC or receiver
Low power
Check aircraft power draw and increase battery
power or decrease power demand by installed
systems. Ensure all aircraft batteries are fully
charged. Ensure the installed BEC for an electric
aircraft is adequate for the power demand
