Problem

Possible Cause

Solution

Aircraft will not respond to throttle but 
responds to other controls

• Throttle not at idle at control setup so throttle 

 

not armed

• Throttle channel is reversed

• Bind with throttle stick and throttle trim at 

 

lowest setting 

• Reverse throttle channel on transmitter

Extra propeller noise or extra vibration

• Damaged propeller, motor or motor mount
• Loose propeller and spinner
• Propeller blades installed backwards 

• Replace damaged parts
• Tighten parts for propeller and spinner
• Remove and install propeller blades correctly

Reduced flight time or aircraft  
underpowered

• Flight battery charge is low
• Propeller blades installed backwards
• Flight battery damaged

• Completely recharge flight battery
• Remove and install propeller blades correctly
• Replace flight battery and obey flight battery 

instructions

LED on receiver flashes rapidly  with bind 

plug installed and aircraft will not link to 

transmitter

• Transmitter too near aircraft during 

 

binding process

• Aircraft not bound to transmitter

• Aircraft bound to different model memory 

 

(ModelMatch radios only)

• Low charge in transmitter batteries

• Disconnect then reconnect flight battery 

 

to aircraft

• Move transmitter a few feet from aircraft, 

 

disconnect and reconnect flight battery to  

aircraft and re-bind

• Bind transmitter to aircraft receiver 

• Select correct model memory on transmitter

• Replace or charge transmitter batteries

Control surface does not move, or is slow 
to respond to control inputs. 

• Control surface, control horn, linkage or 

 

servo damage

• Wire damaged or connections loose

• Parts not secured in fuselage

• Replace or repair damaged parts and 

 

adjust controls

• Do a check of wires and connections for lose 

wiring, connect or replace as needed

• Make hook and loop fastenings tight so no parts 

move in fuselage

Controls reversed

•  Channels need to be reversed in receiver

• Do the Control Direction Test and adjust controls 

on transmitter appropriately

Motor loses power

• Damage to motor,  or power components

• Do a check of batteries, transmitter, receiver, 

ESC, motor and wiring for damage (replace as 

needed)

Motor power pulses then motor loses 
power

• ESC uses default soft Low Voltage Cutoff (LVC)

• Recharge or replace flight battery
