- H
  Heather SmithJul 31, 2025
  If a control surface on your E-FLITE Toy isn't moving, consider these potential causes: 1. There may be damage to the control surface, control horn, linkage, or servo. Replace or repair any damaged parts and adjust the controls. 2. Damaged wires or loose connections could be the culprit. Check the wires and connections, reconnecting or replacing them as necessary. 3. A low flight battery charge can prevent movement. Fully recharge the flight battery. 4. The control linkage might not be moving freely. Ensure that it can move without obstruction.

  If the motor on your E-FLITE Toy is losing power, it could be due to: * Damage to the motor or power components. Inspect these for damage and replace them if needed. * The prop shaft nut being too tight. Loosen it until the propeller shaft turns freely.

What to do if motor power quickly decreases and increases then motor loses power on my E-FLITE Toy?
- E
  Elizabeth JacobsAug 13, 2025
  If the motor power on your E-FLITE Toy quickly decreases and increases before the motor loses power, the battery power is likely low, triggering the receiver/ESC Low Voltage Cutoff (LVC). Recharge the flight battery or replace it if it's no longer performing adequately.

Why is the motor/ESC not armed after landing on my E-FLITE Toy?
- J
  Jessica CookAug 17, 2025
  If the motor/ESC on your E-FLITE Toy is not armed after landing, the Over Current Protection (OCP) may be stopping the motor because the transmitter throttle is set too high and the propeller cannot turn. Fully lower the throttle and throttle trim to arm the ESC.

Why does the servo lock or freeze at full travel on my E-FLITE Toy?
- M
  Mrs. Michelle RodgersAug 21, 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.
