Problem Possible Cause Solution
Aircraft will
not respond to
throttle but re-
sponds 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 set up 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 fl ight conditions Replace battery or use a larger capacity battery
Aircraft will not
Bind (during
binding) to trans-
mitter 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 link (after
binding) to trans-
mitter Transmitter too close to aircraft during linking
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 (Model-
Match™ radios only) Select correct model memory on transmitter
Transmitter may have been bound 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 loca-
tion and attempt linking again
Control surface
does not move Control surface, control horn, linkage or
servo damage Replace or repair damaged parts and adjust
controls
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 decreas-
es 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
