Why is the LED on my E-FLITE Toy receiver flashing rapidly after binding?
- C
  Cynthia GrahamAug 9, 2025
  If the LED on the receiver of your E-FLITE Toy flashes rapidly and the aircraft doesn't respond after binding, there are several potential causes. First, ensure you wait at least 5 seconds after powering on the transmitter before connecting the flight battery to the aircraft. If that doesn't work, and you're using a ModelMatch™ radio, verify that the correct model memory is selected on the transmitter. Also, check and replace or recharge the flight and transmitter batteries if their charge is too low. Ensure the transmitter is bound to the correct model and DSM Protocol, or re-bind to the correct transmitter. Finally, try moving the aircraft and transmitter away from large metal objects, wireless sources, or other transmitters to avoid interference.

  If a control surface on your E-FLITE Toy isn't moving, it could be due to several reasons. Inspect the control surface, control horn, linkage, and servo for any damage; replace or repair any damaged parts and adjust the controls. Check all wires and connections for damage or looseness, and connect or replace them as necessary. Ensure the flight battery is fully charged. Also, make sure the control linkage moves freely.

Why does the motor power on my E-FLITE UMX F4U corsair decrease and increase then lose power?
- P
  pamelamooreAug 19, 2025
  If the motor power of your E-FLITE Toy quickly decreases and increases before the motor loses power, it's likely that the battery power has dropped to the point where the receiver/ESC Low Voltage Cutoff (LVC) is activated. Recharge the flight battery or replace it if it's no longer performing optimally.

What to do if motor/ESC is not armed after landing with my E-FLITE UMX F4U corsair?
- M
  Mitchell ThomasAug 28, 2025
  If the motor/ESC on your E-FLITE Toy is not armed after landing, it's possible that the Over Current Protection (OCP) has stopped the motor because the transmitter throttle is set too high and the propeller cannot turn. To resolve this, fully lower the throttle and throttle trim to arm the ESC.

Why does the servo lock on my E-FLITE Toy?
- A
  Alexis BurnsSep 3, 2025
  If the servo on your E-FLITE Toy locks or freezes at full travel, the travel adjust value is likely set above 100%, overdriving the servo. Set the travel adjust to 100% or less, and/or set sub-trims to zero and adjust the linkages mechanically.
