Why is my Horizon Hobby ICON A5 oscillating?
- K
  Kevin YatesAug 17, 2025
  Oscillation in your Horizon Hobby Toy can stem from several causes. It might be due to a damaged or imbalanced propeller or spinner, which would require replacement or balancing. Motor vibration can also be a factor, suggesting a need to replace parts or correctly align and tighten fasteners. Other potential causes include a loose receiver or aircraft controls, necessitating alignment and securement or tightening of parts. Worn parts, especially the propeller, spinner, or servo, should be replaced. Finally, irregular servo movement indicates the servo should be replaced.

  Reduced flight time in your Horizon Hobby Toy can occur due to several reasons. Ensure the flight battery is fully charged. If the propeller is installed backwards, reinstall it with the numbers facing forward. A damaged flight battery should be replaced, and you should follow the battery instructions. Cold flight conditions can also affect battery performance, 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.

What causes inconsistent flight performance in Horizon Hobby Toy?
- S
  Stephanie SalazarAug 28, 2025
  Inconsistent flight performance of your Horizon Hobby Toy can be attributed to a few factors. Check if the trim is at neutral; if you've adjusted it more than 8 clicks, adjust the clevis to remove trim. Ensure that Sub-Trim is not being used, as it's not allowed—adjust the servo linkage instead. Also, make sure the aircraft remained immobile for 5 seconds after the battery connection. With the throttle stick in the lowest position, disconnect and reconnect the battery, keeping the aircraft still for 5 seconds.

  Travis LopezAug 30, 2025
  If a control surface on your Horizon Hobby Toy does not move, it could be due to several reasons. There might be damage to the control surface, control horn, linkage, or servo, which would require replacement or repair of the damaged parts, along with control adjustments. Check for any damaged wires or loose connections, connecting or replacing them as needed. Ensure the transmitter is correctly bound or that the correct airplane is selected in the transmitter. A low flight battery charge could also be the cause, so fully recharge it. Lastly, the BEC (Battery Elimination Circuit) of the ESC might be damaged, necessitating ESC replacement.

Why does my Horizon Hobby ICON A5 Toy motor power pulse and then lose power?
- M
  Michael PerkinsSep 2, 2025
  If the motor power pulses and then loses power in your Horizon Hobby Toy, 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. Cold weather conditions can also cause this issue, so consider postponing the flight until it's warmer. The battery could also be old, worn out, or damaged, requiring replacement. Lastly, the battery's C rating might be too small; use the recommended battery.

- A
  Arthur SheaSep 5, 2025
  Excessive propeller noise or vibration in your Horizon Hobby Toy could be due to a damaged propeller, spinner, collet, or motor; replace any damaged parts. The propeller might be out of balance, in which case you should balance or replace it. Also, check if the prop nut is too loose and tighten it.

What to do if Horizon Hobby ICON A5 aircraft will not respond to throttle?
- W
  Wendy MckinneySep 8, 2025
  If your Horizon Hobby Toy aircraft responds to other controls but not to the throttle, it might be because the throttle is not at idle or the throttle trim is too high. Reset the controls with the throttle stick and throttle trim at the lowest setting. Ensure that the throttle servo travel is 100% or greater. The throttle channel could be reversed, so reverse it on the transmitter. Finally, check if the motor is disconnected from the ESC and ensure it is connected.
