Problem Possible Cause Solution

Aircraft will not respond

to throttle but responds

to other controls

Throttle stick and/or throttle trim too high Reset controls with throttle stick and throttle

trim at lowest setting

Throttle channel is reversed Reverse throttle channel on transmitter

Motor disconnected from receiver Open fuselage and make sure motor is

connected to the receiver

Extra propeller noise or

extra vibration

Damaged propeller, spinner or motor Replace damaged parts

Prop screw is too loose Tighten the prop screw

Prop is out of balance Remove and balance propeller, or replace

with a balanced propeller.

Reduced ﬂ ight time or

aircraft underpowered

Flight battery charge is low Completely recharge ﬂ ight battery

Propeller installed backwards Install propeller with numbers facing forward

Flight battery 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 too low for ﬂ ight conditions Replace battery or use a larger capacity

battery

LED on receiver ﬂ ashes

and aircraft will not bind

to transmitter (during

binding)

Transmitter too near aircraft during binding

process

Power off transmitter, move transmitter a

larger distance from aircraft, disconnect and

reconnect ﬂ ight battery to aircraft and follow

binding instructions

Bind switch or button not held long enough

during bind process

Power off transmitter and repeat bind pro-

cess. Hold transmitter bind button or switch

until receiver is bound

LED on receiver ﬂ ashes

rapidly and aircraft will

not respond to transmit-

ter (after binding)

Less than a 5-second wait between ﬁ rst

powering on transmitter and connecting

ﬂ ight battery to aircraft

Leaving transmitter on, disconnect and

reconnect ﬂ ight battery to aircraft

Aircraft bound to different model memory

(ModelMatch

™

radios only)

Select correct model memory on transmitter

and disconnect and reconnect ﬂ ight battery

to aircraft

Flight battery/transmitter battery charge is

too low

Replace/recharge batteries

Control surface does

not move

Control surface, control horn, linkage or

servo damage

Replace or repair damaged parts and adjust

controls

Wire damaged or connections loose Do a check of wires and connections, con-

nect or replace as needed

Flight battery charge is low Fully recharge ﬂ ight battery

Control linkage does not move freely Make sure control linkage moves freely

Controls reversed Transmitter settings reversed Adjust controls on transmitter appropriately

Motor loses power Damage to motor or power components Do a check of motor and power components

for damage (replace as needed)

Motor power quickly

decreases and in-

creases then motor

loses power

Battery power is down to the point of

receiver/ESC Low Voltage Cutoff (LVC)

Recharge ﬂ ight battery or replace battery that

is no longer performing

Motor/ESC is not armed

after landing

Over Current Protection (OCP) stops the

motor when the transmitter throttle is set

high and the propeller cannot turn

Fully lower throttle and throttle trim to arm

ESC

Servo locks or freezes

at full travel

Travel adjust value is set above 100%,

overdriving the servo

Set Travel adjust to 100% or less and/or set

sub-trims to Zero and adjust linkages

mechanically
