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 fl ight 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
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 fl ight 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
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 and perpendicular to each other
Receiver quits 
responding during 
operation
Low battery voltage
Completely recharge fl ight 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
Transmitter stand or tray could be pressing the bind 
button
If stand is pressing bind button, remove from stand and 
rebind
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 pow-
ered 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. nsure the installed BEC 
for an electric aircraft is adequate for the power demand
