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

Disconnect and reconnect the fl ight battery 
while keeping the aircraft still for 5 seconds

Model fl ies inconsis-
tently from fl ight to 
fl ight

Aircraft was not kept immobile for 5 
seconds after battery was plugged in

Keep the aircraft immobile for 5 seconds after 
plugging in the battery

Trims are moved too far from neutral 
position

Neutralize trims and mechanically adjust 
linkages to center control surfaces

Controls oscillate in 
fl ight, (model rapidly 
jumps or moves)

Propeller is unbalanced, causing excessive 
vibration

Remove propeller and rebalance or replace it 
if damaged

Nut on prop shaft is too loose, causing 
excessive vibration

Tighten the prop shaft nut 1/2 turn

Aircraft will not respond 
to throttle but responds 
to other controls

Throttle stick and/or throttle trim too high

Reset controls with throttle stick and throttle 
trim at lowest setting

Throttle channel is reversed

Reverse throttle channel on transmitter

Motor disconnected from receiver

Open fuselage and make sure motor is 
connected to the receiver

Extra propeller noise or 
extra vibration

Damaged propeller, spinner or motor

Replace damaged parts

Prop is out of balance

Remove and balance propeller, or replace 
with a balanced propeller

Reduced fl ight time or 
aircraft underpowered

Flight battery charge is low

Completely recharge fl ight battery

Propeller installed backwards

Install propeller with numbers facing forward

Flight battery 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 too low for fl ight conditions

Replace battery or use a larger capacity 
battery

LED on receiver fl ashes 
and 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 pro-
cess. Hold transmitter bind button or switch 
until receiver is bound

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
