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

conditions
Replace battery or use a larger capacity
battery
LED on receiver
fl ashes rapidly
and aircraft will
