Техническая Спецификация для E-flite RTB 1220 mm EFL10550

Problem

Possible Cause

Solution

Aircraft will not re-
spond to throttle but 
responds to other 
controls

Throttle not at idle and/or throttle trim too high

Reset controls with throttle stick and throttle trim at lowest setting

Throttle servo travel is lower than 100%

Make sure throttle servo travel is 100% or greater

Throttle channel is reversed

Reverse throttle channel on transmitter

Motor disconnected from ESC

Make sure motor is connected to the ESC

Extra propeller noise 
or extra vibration

Damaged propeller and spinner, collet or motor

Replace damaged parts

Propeller is out of balance

Balance or replace propeller

Prop nut is too loose

Tighten the prop nut

Spinner is not tight or fully seated in place

Tighten the spinner or remove the spinner and turn it 180 degrees

Reduced fl ight time 
or aircraft under-
powered

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 flight conditions

Replace battery or use a larger capacity battery

Aircraft will not Bind 
(during binding) to 
transmitter

Transmitter too near aircraft during binding process

Move powered transmitter a few feet from aircraft, disconnect and reconnect 
fl ight battery to aircraft

Aircraft or transmitter is too close to large metal
object, wireless source or another transmitter

Move aircraft and transmitter to another location and attempt binding again

The bind plug is not installed correctly in the bind port  Install bind plug in bind port and bind the aircraft to the transmitter

Flight battery/transmitter battery charge is too low

Replace/recharge batteries

Bind switch or button not held long enough during 
bind process

Power off transmitter and repeat bind process. Hold transmitter bind 
button or switch until receiver is bound

ESC is powered off

Power on the ESC switch

Aircraft will not con-
nect (after binding) 
to transmitter

Transmitter too near aircraft during connecting
process

Move powered transmitter a few feet from aircraft, disconnect and reconnect 
fl ight battery to aircraft

Aircraft or transmitter is too close to large metal
object, wireless source or another transmitter

Move aircraft and transmitter to another location and attempt connecting again

Bind plug left installed in bind port

Rebind transmitter to the aircraft and remove the bind plug before cycling power

Aircraft bound to different model memory
(ModelMatch

TM

 radios only)

Select correct model memory on transmitter

Flight battery/Transmitter battery charge is too low

Replace/recharge batteries

Transmitter may have been bound to a different air-
craft using different DSM protocol

Bind aircraft to transmitter

ESC is powered off

Power on the ESC switch

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, connect or replace as needed

Transmitter is not bound correctly or the incorrect 
airplanes was selected

Re-bind or select correct airplanes in transmitter

Flight battery charge is low

Fully recharge fl ight battery

BEC (Battery Elimination Circuit) of the ESC is
damaged

Replace ESC

ESC is powered off

Power on the ESC switch

Controls reversed

Transmitter settings are reversed

Perform the Control Direction Test and adjust the controls on transmitter
appropriately

Motor power pulses 
then motor loses 
power

ESC uses default soft Low Voltage Cutoff (LVC)

Recharge fl ight battery or replace battery that is no longer performing

Weather conditions might be too cold

Postpone flight until weather is warmer

Battery is old, worn out, or damaged

Replace battery

Battery C rating might be too small

Use recommended battery
