Troubleshooting Guide

Problem
Throttle not at idle and/or throttle trim too high
Aircraft will not
Throttle servo travel is lower than 100%
respond to throttle
but responds to
Throttle channel is reversed
other controls
Motor disconnected from ESC
Damaged fan, nose cone, collet or motor
Excessive fan
noise or excessive Fan is out of balance
vibration
Fan nut is too loose
Flight battery charge is low
Reduced flight
Flight battery damaged
time or aircraft
Flight conditions may be too cold
underpowered
Battery capacity too low for flight conditions
Transmitter too near aircraft during binding process
Aircraft or transmitter is too close to large metal
Aircraft will not Bind
object, wireless source or another transmitter
(during binding) to
The bind plug is not installed correctly in the bind port Install bind plug in bind port and bind the aircraft to the transmitter
transmitter
Flight battery/transmitter battery charge is too low
Bind switch or button not held long enough during
bind process
Transmitter too near aircraft during connecting
process
Aircraft or transmitter is too close to large metal
object, wireless source or another transmitter
Aircraft will not
Bind plug left installed in bind port
connect (after
binding) to
Aircraft bound to different model memory
transmitter
(ModelMatchTM radios only)
Flight battery/Transmitter battery charge is too low
Transmitter may have been bound to a different
aircraft using different DSM protocol
Control surface, control horn, linkage or servo damage
Wire damaged or connections loose
Control surface does Transmitter is not bound correctly or the incorrect
not move airplanes was selected
Flight battery charge is low
BEC (Battery Elimination Circuit) of the ESC is damaged Replace ESC
Controls reversed Transmitter settings are reversed
ESC uses default soft Low Voltage Cutoff (LVC)
Motor power pulses
Weather conditions might be too cold
then motor loses
Battery is old, worn out, or damaged
power
Battery C rating might be too low

Replace rotor or nose cone
Balance the rotor
Replace parts or correctly align fan unit or other parts and tighten fasteners as needed
Align and secure receiver in fuselage
Tighten or otherwise secure parts (servo, arm, linkage, horn and control surface)
Replace worn parts (especially rotor, nose cone, or servo)
Replace servo
If you adjust trim more than 8 clicks, adjust the ball link to remove trim
No Sub-Trim is allowed. Adjust the servo linkage
With the throttle stick in lowest position. Disconnect battery, then reconnect battery and keep the aircraft
still for 5 seconds
DO NOT fly. Correct the direction settings (refer to the receiver manual), then fly
Possible Cause
Solution
Reset controls with throttle stick and throttle trim at lowest setting
Make sure throttle servo travel is 100% or greater
Reverse throttle channel on transmitter
Make sure motor is connected to the ESC
Replace damaged parts
Balance or replace fan
Tighten the fan nut
Completely recharge flight battery
Replace flight battery and follow flight battery instructions
Make sure battery is not cold before use (Do not apply heat to the battery)
Replace battery or use a larger capacity battery
Move powered transmitter a few feet from aircraft, disconnect and reconnect flight
battery to aircraft
Move aircraft and transmitter to another location and attempt binding again
Replace/recharge batteries
Power off transmitter and repeat bind process. Hold transmitter bind button or switch
until receiver is bound
Move powered transmitter a few feet from aircraft, disconnect and reconnect flight
battery to aircraft
Move aircraft and transmitter to another location and attempt connecting again
Rebind transmitter to the aircraft and remove the bind plug before cycling power
Select correct model memory on transmitter
Replace/recharge batteries
Bind aircraft to transmitter
Replace or repair damaged parts and adjust controls
Do a check of wires and connections, connect or replace as needed
Re-bind or select correct airplanes in transmitter
Fully recharge flight battery
Perform the Control Direction Test and adjust the controls on transmitter appropriately
Recharge flight battery or replace battery that is no longer performing
Postpone flight until weather is warmer
Replace battery
Use recommended battery
