Problem
Possible Cause Solution
Reduced fl ight
time or aircraft
underpowered Flight battery charge is low Completely recharge fl ight battery
Propeller is installed backwards Install propeller with numbers facing forward
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 is too low for fl ight
conditions Replace battery or use a larger capacity
battery
LED on receiver
fl ashes rapidly
and aircraft
will not bind
to transmitter
(during binding) Transmitter is 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 was not held
while transmitter was powered on Power off transmitter and repeat bind process
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
LED on receiver
fl ashes rapidly
and aircraft will
not respond to
transmitter (after
binding) Less than a 5-second wait between
fi rst powering on transmitter and
connecting fl ight battery to aircraft Leaving transmitter on, disconnect and
reconnect fl ight battery to aircraft
Aircraft is bound to a different model
memory (ModelMatch

Select correct model memory on transmitter
and disconnect and reconnect fl ight battery
to aircraft
Flight battery/transmitter battery
charge is too low Replace/recharge batteries
Transmitter may have been bound to

of power Battery power is down to the point of
receiver/ESC Low Voltage Cutoff (LVC) Recharge fl ight battery or replace battery that
is no longer performing
Servo locks or
freezes at full
travel Travel adjust value is set above 100%
overdriving the servo Set Travel adjust to 100% or less and/or
set sub trims to Zero and adjust linkages
