What to do if E-FLITE Horizon Hobby UMX Voodoo P-51D have reduced flight time?
- M
  Melissa ScottAug 3, 2025
  If your E-FLITE Drone has a reduced flight time, several factors could be the cause. First, completely recharge the flight battery. If that doesn't work, check if the propeller is installed backwards and, if so, install it with the numbers facing forward. The flight battery may also be damaged, in which case you should replace it, following the battery instructions. Cold flight conditions can also reduce flight time, so ensure the battery is warm before use. Finally, the battery capacity might be too low for the flight conditions; consider replacing it with a larger capacity battery.

Why E-FLITE Horizon Hobby UMX Voodoo P-51D aircraft will not respond to throttle?
- S
  susanfloresAug 7, 2025
  If your E-FLITE Drone doesn't respond to the throttle but responds to other controls, the throttle stick or trim may be too high; reset the controls with both at their lowest settings. Another potential reason is that the throttle channel is reversed; reverse the throttle channel on the transmitter. Finally, the motor may be disconnected from the receiver; open the fuselage and ensure the motor is properly connected.

What to do if E-FLITE Horizon Hobby UMX Voodoo P-51D controls oscillate in flight?
- D
  dwayne83Aug 15, 2025
  If the controls on your E-FLITE Drone are oscillating in flight (rapidly jumping or moving), there are a couple of things to check. First, the propeller might be unbalanced, causing excessive vibration; remove the propeller and rebalance it, or replace it if it is damaged. Also, make sure that the propeller screw is not loose, causing vibration; if it is, tighten the propeller screw.

Why LED on receiver flashes and E-FLITE Horizon Hobby UMX Voodoo P-51D will not bind to transmitter?
- K
  Karen GonzalezAug 20, 2025
  If the LED on the receiver of your E-FLITE Drone flashes and the aircraft won't bind to the transmitter, it could be due to several reasons. The transmitter might be too close to the aircraft during binding; power off the transmitter, move it further away from the aircraft, disconnect and reconnect the flight battery, and then follow the binding instructions. Also, the bind switch or button might not be held long enough; power off the transmitter and repeat the binding process, holding the bind button or switch until the receiver is bound. Finally, the aircraft or transmitter might be too close to a large metal object, wireless source, or another transmitter; move the aircraft and transmitter to another location and try binding again.

Why E-FLITE Horizon Hobby UMX Voodoo P-51D Drones model flies inconsistently from flight to flight?
- P
  Philip SimsAug 25, 2025
  If your E-FLITE Drone flies inconsistently from flight to flight, ensure the aircraft remains immobile for 5 seconds after plugging in the battery. Also, if the trims are moved too far from the neutral position, neutralize the trims and mechanically adjust the linkages to center the control surfaces.

How to fix E-FLITE Horizon Hobby UMX Voodoo P-51D control surfaces not at neutral position?
- P
  Paula PooleAug 28, 2025
  If the control surfaces of your E-FLITE Drone are not at the neutral position when the transmitter controls are at neutral, it could be because the control surfaces were not mechanically centered at the factory; center them mechanically by adjusting the U-bends on the control linkages. Another possibility is that the aircraft was moved after the flight battery was connected and before the sensors initialized; disconnect and reconnect the flight battery while keeping the aircraft still for 5 seconds.
