Troubleshooting Guide
Problem Possible Cause Solution
Aircraft will
not respond to
throttle but re-
sponds to other
controls Throttle stick and/or throttle trim is too
high Reset controls with throttle stick and
throttle trim at lowest setting
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
Extra propeller
noise or extra
vibration Damaged propeller, prop shaft or motor Replace damaged parts
Nut on prop shaft is too loose Tighten the prop shaft nut 1/2 turn
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
Problem Possible Cause Solution
Control surfaces
not at neutral po-
sition when trans-
mitter 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 link-
ages
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 in-
consistently 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, (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, caus-
ing excessive vibration. Tighten the prop shaft nut 1/2 turn

1. Disconnect the fl ight battery from the
ESC (Required for safety and battery
life).
2. Power OFF the transmitter.
3. Remove the fl ight battery from the
aircraft.

4. Recharge the fl ight battery.
5. Store the fl ight battery apart from the
aircraft and monitor the battery charge.
6. Make note of the fl ight conditions and
fl ight plan results, planning for future
fl ights.
