Problem
Possible Cause
Solution
Aircraft will
not respond
to throttle but
responds to
other controls
ESC did not arm because throttle stick and/or
throttle trim too high
Lower throttle stick and throttle trim to lowest
setting
Throttle channel is reversed
Reverse throttle channel on transmitter
Motor disconnected from ESC
Make sure motor is connected to the ESC
Servo travel setup is less than 100%
Adjust servo travel to 100% or slightly greater
Extra propeller
noise or extra
vibration
Damaged propeller, spinner or motor
Replace damaged parts
Prop nut is too loose
Tighten the prop nut
Prop is out of balance
Remove and balance propeller, or replace with
a balanced propeller
Spinner is not tight or fully seated in place
Tighten the spinner or remove the spinner and
turn it 180 degrees
Reduced fl ight
time or aircraft
underpowered
Flight battery charge is low
Completely recharge fl ight battery
Propeller installed backwards
Install propeller properly
Flight battery damaged
Replace fl ight battery and follow fl ight battery
instructions
Flight battery is too cold
Make sure battery is warm before use
Battery capacity too low for power drawn
Replace battery or use a larger capacity battery
Aircraft will not
Bind (during
binding) to
transmitter
Transmitter too near aircraft during binding process
Power off transmitter, move transmitter a
larger distance from aircraft, disconnect and
reconnect fl ight battery to aircraft and follow
binding instructions
Bind switch or button not held long enough during
bind process
Power off transmitter and repeat bind process.
Hold transmitter bind button or switch until
receiver is bound
Flight battery/Transmitter battery charge is too low
Replace/recharge batteries
Bind pins on receiver are not correctly
connected
Connect receiver bind pins as instructed and
bind transmitter to receiver
Aircraft or transmitter is too close to large metal
object, wireless source or another transmitter
Move aircraft and transmitter to another
location and attempt binding again
Aircraft will not
connect (after
binding) to
transmitter
Transmitter too close to aircraft during connecting
process
Power off transmitter, move transmitter a
larger distance from aircraft, disconnect and
reconnect fl ight battery to aircraft
Flight battery/Transmitter battery charge is too low
Replace/recharge batteries
Aircraft bound to different model memory
(ModelMatch™ radios only)
Select correct model memory on transmitter
Transmitter may have been bound to a different
aircraft using different DSM protocol
Bind aircraft to transmitter
Bind pins on receiver are connected
Ensure bind pins on receiver are not connected
Aircraft or transmitter is too close to large metal
object, wireless source or another transmitter
Move aircraft and transmitter to another
location and attempt connecting again
Control surface
does not move
Control surface, control horn, linkage or
servo damage
Replace or repair damaged parts and adjust
controls
Servo wire damaged or connections loose
Do a check of wires and connections, connect
or replace as needed
Flight battery charge is low
Fully recharge fl ight battery
Control linkage does not move freely
Make sure control linkage moves freely
Controls reversed Transmitter settings reversed
Adjust controls on transmitter appropriately
Motor power
quickly
decreases and
increases then
motor loses
power
Battery voltage is down to the point of receiver/ESC
Low Voltage Cutoff (LVC)
Recharge fl ight battery or replace battery that
is no longer performing
