What to do if my Horizon Hobby Toy aircraft will not respond to throttle?
- A
  Anthony WilliamsAug 17, 2025
  If your Horizon Hobby Toy aircraft isn't responding to the throttle but responds to other controls, there might be several reasons: * The throttle might not be at idle, or the throttle trim may be too high. To fix this, reset the controls with the throttle stick and throttle trim at their lowest settings. * The throttle servo travel might be less than 100%. Ensure the throttle servo travel is 100% or greater. * The throttle channel could be reversed. If so, reverse the throttle channel on the transmitter. * The motor might be disconnected from the ESC. Ensure the motor is connected to the ESC.

  Oscillation in your Horizon Hobby Toy aircraft can stem from several issues: * A damaged propeller or spinner. Consider replacing the propeller or spinner. * An imbalanced propeller. Balance the propeller. * Motor vibration. Replace parts or correctly align all parts and tighten fasteners as needed. * A loose receiver. Align and secure the receiver in the fuselage. * Loose aircraft controls. Tighten or otherwise secure parts such as the servo, arm, linkage, horn, and control surface. * Worn parts. Replace worn parts, especially the propeller, spinner, or servo. * Irregular servo movement. Replace the servo.

Why does Horizon Hobby Toy motor power pulse and then lose power?
- N
  nathan50Sep 2, 2025
  If the motor power in your Horizon Hobby Toy pulses and then loses power, consider these factors: * The ESC may be using a default soft Low Voltage Cutoff (LVC). Recharge the flight battery or replace it if it's no longer performing well. * The weather conditions might be too cold. Consider postponing the flight until the weather is warmer. * The battery might be old, worn out, or damaged. Replace the battery. * The battery's C rating might be too small. Use the recommended battery.

Why does my Horizon Hobby E-flite Pitts S-1S have inconsistent flight performance?
- K
  Kim JohnsonSep 5, 2025
  If you're experiencing inconsistent flight performance with your Horizon Hobby Toy aircraft, here are a few things to check: * Ensure the trim is at neutral. If you adjust the trim more than 8 clicks, adjust the clevis to remove trim. * Sub-Trim is not allowed. Adjust the servo linkage. * Make sure the aircraft remained immobile for 5 seconds after connecting the battery. Disconnect and reconnect the battery with the throttle stick in the lowest position, then keep the aircraft still for 5 seconds.
