Problem
Possible Cause
Solution
Control surfaces not at
neutral position when
transmitter controls are at
neutral
Control surfaces may not have been
mechanically centered from factory
Center control surfaces mechanically by
adjusting the U-bends on control
linkages
Aircraft was moved after the fl ight
battery was connected and before
sensors initialized
Keep the Aircraft upright and immobile
for 5 seconds after connecting the
battery
SAFE may be active and plane is
not level
Normal operation, review the SAFE
control direction test in this manual for
more details
Aircraft fl ies inconsistently
from fl ight to fl ight
Trims are moved too far from
neutral position
Neutralize trims and mechanically adjust
linkages to center control surfaces
Controls oscillate in fl ight,
(Aircraft rapidly jumps or
moves)
Propeller is unbalanced, causing
excessive vibration
Remove propeller and rebalance or
replace it if damaged
The three spinner screws are loose,
causing excessive vibration
Tighten spinner screws
The motor screw in the bottom of
the plane may be loose
Tighten motor screw
Aircraft does not connect
to transmitter after battery
is connected
Aircraft is not upright and immobile
after battery is connected
Keep the Aircraft upright and immobile for
5 seconds after connecting the battery
Aircraft was powered on before
transmitter and entered bind mode
Power on the transmitter before the
aircraft, except when binding
Problem
Possible Cause
Solution
Aircraft will
not respond
to throttle but
responds to
other controls
Throttle stick not lowered or and/or
throttle trim not centered
Reset controls with throttle stick at lowest
setting and throttle trim centered
Throttle channel is reversed
Reverse throttle channel on transmitter
Motor is disconnected from receiver
Open fuselage and ensure the plug for the
motor is properly installed
throttle cut active
deactivate throttle cut
Extra propeller
noise or extra
vibration
Damaged propeller, prop shaft or
motor
Replace damaged parts
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
