What to do if LED on receiver flashes rapidly and Horizon Hobby E-flite UMX NIGHT VAPOR RTF aircraft will not respond to transmitter after binding?

  Dale JonesAug 14, 2025
  If the LED on the receiver flashes rapidly and the aircraft doesn't respond after binding, it could be due to several reasons. Firstly, 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, the flight battery or transmitter battery charge may be too low, so try replacing or recharging the batteries. Also, the transmitter might be bound to a different model, so select the correct transmitter or bind to the new one. Finally, check for interference by moving the aircraft and transmitter away from large metal objects, wireless sources, or other transmitters.

Why does LED on receiver flash rapidly and Horizon Hobby E-flite UMX NIGHT VAPOR RTF Toy aircraft will not bind to transmitter during binding?
- N

  The rapid flashing of the LED on the receiver during binding, preventing the aircraft from binding to the transmitter, can occur due to a few reasons. The transmitter might be too close to the aircraft during the binding process; in this case, power off the transmitter, increase the distance between them, disconnect and reconnect the flight battery to the aircraft, and then follow the binding instructions. Another reason could be that the bind button wasn't held while the transmitter was powered on, so power off the transmitter and repeat the bind process, ensuring the button is held. Lastly, interference from large metal objects, wireless sources, or other transmitters nearby could be the cause; move the aircraft and transmitter to a different location and try binding again.

  If your aircraft isn't responding to the throttle but responds to other controls, there are a couple of things you can check: * Ensure the throttle stick and/or throttle trim are at the lowest setting. Reset the controls with the throttle stick and throttle trim in the lowest position. * Also, verify that the motor is properly connected to the receiver by ensuring the plug for the motor is securely installed.

Why does my Horizon Hobby E-flite UMX NIGHT VAPOR RTF have reduced flight time or is underpowered?
- S
  Sandra WagnerAug 28, 2025
  Reduced flight time or an underpowered aircraft can stem from several factors. First, ensure that the flight battery is fully charged. If the battery is damaged, replace it, adhering to the battery instructions. Cold flight conditions can also impact performance, so warm the battery before use. Finally, the battery capacity might be insufficient for the flight conditions; consider replacing it with a larger capacity battery.

Why does Horizon Hobby E-flite UMX NIGHT VAPOR RTF Toy motor power pulse then have loss of power?
- M
  Megan SmithSep 1, 2025
  If the motor power pulses and then cuts out, it's likely due to the battery power dropping to the point of receiver/ESC Low Voltage Cutoff (LVC). Recharge the flight battery or replace it if it's no longer performing adequately.
