Problem Possible Cause Solution
Aircraft will not respond
to throttle but responds to
other controls Throttle is not at idle and/or throttle trim is too high Reset controls with throttle stick and throttle trim
at lowest setting
Throttle servo travel is lower than 100% Make sure throttle servo travel is 100% or greater
Throttle channel is reversed Reverse throttle channel on transmitter
Extra propeller noise or
extra vibration Damaged propeller and spinner, collet or motor Replace damaged parts
Propeller is out of balance Balance or replace propeller
Reduced fl ight time or air-
craft underpowered Flight battery charge is low Completely recharge fl ight battery
Propeller is installed backwards Install propeller with numbers facing forward towards the
front of the aircraft
Flight battery is damaged Replace fl ight battery and follow fl ight battery instructions
Flight conditions may be too cold Make sure battery is warm before use
Battery capacity may be too low for fl ight conditions Replace battery or use a larger capacity battery
Aircraft will not Bind (dur-
ing binding) to transmitter Transmitter is 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 aircraft or transmitter away from large metal object
Bind plug is not installed correctly in bind port extension Install bind plug in bind port extension and bind
aircraft to transmitter
Flight battery/Transmitter battery charge is too low Replace/recharge batteries
ESC switch is off Power on ESC switch
Aircraft will not link (after
binding) to transmitter Transmitter is 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 aircraft or transmitter away from large metal object
Bind plug is left installed in bind port extension Rebind transmitter to aircraft and remove 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 to a different model (using
different DSM Protocol) Bind aircraft to transmitter
ESC switch is off Power on ESC switch
Control surface does not
move Control surface, control horn, linkage or servo damage Replace or repair damaged parts and adjust controls
Wire is damaged or connections are loose Do a check of wires and connections, connect
or replace as needed
Transmitter is not bound correctly or the incorrect model
was selected Re-bind or select correct model in transmitter
BEC (Battery Elimination Circuit) of the ESC is damaged Replace ESC
ESC switch is off Power on ESC switch
Controls reversed Transmitter settings are reversed Do the Control Direction Test and adjust controls on
transmitter appropriately
Motor power pulses then
motor loses power ESC uses default soft Low Voltage Cutoff (LVC) Recharge fl ight battery or replace battery
that is no longer performing
Weather conditions might be too cold Postpone flight until weather is warmer
Battery is old, worn out or damaged Replace battery
Battery C rating might be too small Use recommended 25C battery
