- F
  Frederick McdonaldAug 13, 2025
  If your E-FLITE Toy aircraft won't respond to the throttle but responds to other controls, first, ensure the throttle stick and trim are at their lowest settings by resetting the controls. Also, verify that the throttle servo travel is at least 100%. Check if the throttle channel is reversed and correct it on the transmitter if needed. Finally, make sure the motor is properly connected to the ESC.

How to fix oscillation in E-FLITE Viper 70mm EDF Toy aircraft?

  brian00Aug 17, 2025
  If your E-FLITE Toy aircraft exhibits oscillation, it might be due to several factors. Check for a damaged propeller or spinner and replace them if necessary. Ensure the propeller is balanced. Address any motor vibration by replacing parts or correctly aligning and tightening fasteners. Secure a loose receiver in the fuselage and tighten any loose aircraft controls, such as servos, arms, linkages, horns, and control surfaces. Replace any worn parts, especially the propeller, spinner, or servo. If there is irregular servo movement, replace the servo.

What to do if E-FLITE Viper 70mm EDF Toy aircraft will not connect to transmitter after binding?
- C
  Carol JamesAug 21, 2025
  If your E-FLITE Toy aircraft will not connect to the transmitter after binding, the transmitter may be too close to the aircraft; move it a few feet away and reconnect the flight battery. Ensure that neither the aircraft nor the transmitter is near large metal objects, wireless sources, or other transmitters. Rebind the transmitter to the aircraft and remove the bind plug. Select the correct model memory on the transmitter. Replace or recharge batteries if the flight or transmitter battery charge is too low. If the transmitter was bound to a different aircraft using a different DSM protocol, bind the aircraft to the transmitter.

  If your E-FLITE Toy aircraft will not bind to the transmitter, move the transmitter a few feet away from the aircraft and try again. Ensure that the aircraft and transmitter are not near any large metal objects, wireless sources, or other transmitters. Verify that the bind plug is correctly installed in the bind port. Replace or recharge the batteries in both the flight battery and the transmitter if their charge is low. Power off the transmitter and repeat the bind process, holding the bind button or switch until the receiver is bound.

Why is E-FLITE Viper 70mm EDF aircraft flight time reduced?
- D
  Debra MeyerSep 1, 2025
  If you are experiencing reduced flight time or underpowered performance with your E-FLITE Toy aircraft, fully recharge the flight battery. Make sure the propeller is installed correctly with the numbers facing forward. If the flight battery is damaged, replace it, following the battery instructions. Ensure the battery is warm before use, as cold flight conditions can affect performance. Consider replacing the battery or using a larger capacity battery if the current one is too low for the flight conditions.

Why E-FLITE Viper 70mm EDF Toy has inconsistent flight performance?
- B
  Bryan HaleySep 5, 2025
  If your E-FLITE Toy aircraft exhibits inconsistent flight performance, ensure the trim is at neutral; if you adjust trim more than 8 clicks, adjust the clevis to remove trim. Sub-Trim is not allowed, so adjust the servo linkage. Also, after connecting the battery, keep the aircraft immobile for 5 seconds with the throttle stick in the lowest position.
