Problem
Control surfaces not at Control surfaces may not have been
neutral position when mechanically centered from factory
transmitter controls are
Aircraft was moved after the fl ight battery
at neutral
was connected and before sensors
initialized
Model fl ies inconsis- Aircraft was not kept immobile for 5
tently from fl ight to seconds after battery was plugged in
fl ight
Trims are moved too far from neutral
position
Controls oscillate in Propeller is unbalanced, causing excessive
fl ight, (model rapidly vibration
jumps or moves)
Nut on prop shaft is too loose, causing
excessive vibration
Problem
Aircraft will not respond Throttle stick and/or throttle trim too high
to throttle but responds
to other controls
Throttle channel is reversed
Motor disconnected from receiver
Extra propeller noise or Damaged propeller, spinner or motor
extra vibration
Prop is out of balance
Reduced fl ight time or Flight battery charge is low
aircraft underpowered
Propeller installed backwards
Flight battery damaged
Flight conditions may be too cold
Battery capacity too low for fl ight conditions Replace battery or use a larger capacity
LED on receiver fl ashes Transmitter too near aircraft during binding
and aircraft will not bind process
to transmitter (during
binding)
Bind switch or button not held long enough
during bind process
Aircraft or transmitter is too close to large
metal object, wireless source or another
transmitter

Possible Cause
Possible Cause
Solution
Center control surfaces mechanically by
adjusting the U-bends on control linkages
Disconnect and reconnect the fl ight battery
while keeping the aircraft still for 5 seconds
Keep the aircraft immobile for 5 seconds after
plugging in the battery
Neutralize trims and mechanically adjust
linkages to center control surfaces
Remove propeller and rebalance or replace it
if damaged
Tighten the prop shaft nut 1/2 turn
Solution
Reset controls with throttle stick and throttle
trim at lowest setting
Reverse throttle channel on transmitter
Open fuselage and make sure motor is
connected to the receiver
Replace damaged parts
Remove and balance propeller, or replace
with a balanced propeller
Completely recharge fl ight battery
Install propeller with numbers facing forward
Replace fl ight battery and follow fl ight battery
instructions
Make sure battery is warm before use
battery
Power off transmitter, move transmitter a
larger distance from aircraft, disconnect and
reconnect fl ight battery to aircraft and follow
binding instructions
Power off transmitter and repeat bind pro-
cess. Hold transmitter bind button or switch
until receiver is bound
Move aircraft and transmitter to another
location and attempt binding again
