Extra 300 1.3 m
Problem Possible Cause Solution
Aircraft will not
respond to throttle
but responds to
other controls
Throttle not at idle and/or throttle trim 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
Motor disconnected from ESC Make sure motor is connected to the ESC
Extra propeller
noise or extra vi-
bration
Damaged propeller and spinner, collet or motor Replace damaged parts
Propeller is out of balance Balance or replace propeller
Prop nut is too loose Tighten the prop nut
Reduced flight
time or aircraft
underpowered
Flight battery charge is low Completely recharge flight battery
Propeller installed backwards Install propeller with numbers facing forward
Flight battery damaged Replace flight battery and follow flight battery instructions
Flight conditions may be too cold Make sure battery is warm before use
Battery capacity too low for flight conditions Replace battery or use a larger capacity battery
Aircraft will not
Bind (during bind-
ing) to transmitter
Transmitter too near aircraft during binding
process
Move powered transmitter a few feet from aircraft, disconnect and re-
connect flight battery to aircraft
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
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
Bind switch or button not held long enough dur-
ing bind process
Power off transmitter and repeat bind process. Hold transmitter bind
button or switch until receiver is bound
Aircraft will not
connect (after
binding) to trans-
mitter
Transmitter too near aircraft during connecting
process
Move powered transmitter a few feet from aircraft, disconnect and re-
connect
flight battery to aircraft
Aircraft or transmitter is too close to large metal
object, wireless source or another transmitter
Move aircraft and transmitter to another location and attempt connect-
ing again
Bind plug left installed in bind port
Rebind transmitter to the aircraft and remove the bind plug before cy-
cling power
Aircraft bound to different model memory
(ModelMatch
TM
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
aircraft using different DSM protocol
Bind aircraft to transmitter
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
Transmitter is not bound correctly or the incor-
rect airplanes was selected
Re-bind or select correct airplanes in transmitter
Flight battery charge is low Fully recharge flight battery
BEC (Battery Elimination Circuit) of the ESC is
damaged
Replace ESC
Controls reversed Transmitter settings are reversed
Perform the Control Direction Test and adjust the controls on transmitter
appropriately
Motor power
pulses then motor
loses power
ESC uses default soft Low Voltage Cutoff (LVC) Recharge flight 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 battery
