Troubleshooting Guide

Problem
• Aircraft will not respond
to throttle but responds to
other controls
• Extra propeller noise or
extra vibration
• Reduced flight time or
aircraft underpowered
• LED on receiver flashes
rapidly and aircraft will
not link to transmitter
• Control surface does not
move
• Controls reversed
• Motor loses power
• Motor power pulses then
motor loses power
• Motor/ESC is not armed
after landing

Possible Cause
• Throttle not at idle and/or throttle
trim too high.
• Throttle channel is reversed
• Damaged propeller and spinner
or motor
• Flight battery charge is low
• Propeller damaged
• Flight battery damaged
• Flight conditions may be too cold
• Battery capacity may be low for
flight conditions.
• Less than a 5-second wait after
powering transmitter and before
connecting flight battery to aircraft
• 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
• Control surface, control horn,
linkage or servo damage
• Wire damaged or connections
loose
• Flight battery charge is low
• Control trim out of adjustment
• Pushrod stuck on dried paint or
decal
• Transmitter settings reversed
• Damage to motor, or power
components
• ESC uses default soft Low Voltage
Cutoff (LVC)
• Over Current Protection (OCP)
stalls motor when the transmitter
throttle is set high and the
propeller cannot turn
Solution
• Reset controls with throttle stick
and throttle trim at lowest setting
• Reverse throttle channel on
transmitter
• Replace damaged parts
• Completely recharge flight battery
• Replace damaged parts
• Replace flight battery and follow
flight battery instructions
• Make sure battery is warm before
use
• Replace battery or use a larger
capacity battery
• Disconnect then reconnect flight
battery to aircraft
• Move powered transmitter a few
feet from aircraft, disconnect and
reconnect flight battery to aircraft
• Bind transmitter to aircraft receiver
• Select correct model memory on
transmitter
• Replace or charge transmitter
batteries
• Replace or repair damaged parts
and adjust controls
• Do a check of wires and
connections, connect or replace as
needed
• Fully recharge flight battery
• Adjust trims to restore full control
• Free pushrod from paint/decal
• Do the Control Direction Test and
adjust controls on transmitter
appropriately
• Do a check of batteries, transmitter,
receiver, ESC, motor and wiring for
damage (replace as needed)
• Recharge flight battery or replace
battery that is no longer performing
• Fully lower throttle and throttle trim
to arm ESC
