Problem
Possible Cause
Solution
Ailerons go up
and aircraft will
not respond to
transmitter (after
binding)
Less than a 90-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 was not upright, level or
motionless
Leaving transmitter on, disconnect
and reconnect fl ight battery to aircraft
assuring that the aircraft is upright, level
and motionless
Control surface does
not move
Control surface, control horn, linkage
or servo damage
Replace or repair damaged parts and
adjust controls
Wires 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 loses power
Damage to motor or power
components
Do a check of motor and power
components for damage (replace as
needed)
Motor power quickly
decreases and
increases then motor
loses 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
Motor does not
respond after landing
Over Current Protection (OCP) stops the
motor when the transmitter throttle is
set high and the propeller cannot turn
Fully lower throttle and throttle trim to
arm ESC
AutoLand has not been deactivated
Press and release HP/AL button to
deactivate AuloLand feature
Servo locks or
freezes at full travel
Travel adjust value is set above 100%,
over driving the servo
Set Travel adjust to 100% or less and/
or set sub-trims to Zero and adjust
linkages mechanically
Problem
Possible Cause
Solution
Ailerons go up
aircraft will not bind
to transmitter (during
binding)
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
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 was not placed upright on its
wheels
Place aircraft upright on its wheels after
powering up
