Why Horizon Hobby champ s+ aircraft does not connect to transmitter?
- C
  Christy LeonardJul 27, 2025
  There are several reasons why your Horizon Hobby Toy aircraft might not connect to the transmitter. Ensure the aircraft remains upright and immobile for 90 seconds after connecting the battery. If you're using a ModelMatch™ radio, verify you've selected the correct model memory. Low battery charge in either the flight or transmitter battery could also be the cause, so try replacing or recharging them. Also, confirm that your transmitter is compatible with Spektrum DSMX/DSM2 technology. Interference from large metal objects, wireless sources, or other transmitters can also prevent connection; try moving to another location.

How to fix Horizon Hobby Toy controls oscillating in flight?

  If the controls of your Horizon Hobby Toy are oscillating in flight, causing rapid jumps or movements, the issue could stem from an unbalanced propeller causing excessive vibration. Remove the propeller and rebalance it, or replace it if it's damaged. Another potential cause is a prop screw that's too loose, leading to vibration. Ensure the prop screw is properly tightened.

What to do if Horizon Hobby champ s+ aircraft will not respond to throttle?
- A
  Alfred HallAug 9, 2025
  If your Horizon Hobby Toy aircraft isn't responding to the throttle but responds to other controls, start by resetting the controls with the throttle stick and trim at the lowest setting. Also, check if the throttle channel is reversed and correct it on the transmitter. Ensure the motor is properly connected to the receiver by opening the fuselage. Another reason could be that AutoLand was not deactivated after landing. Deactivate AutoLand by pressing the AL/HP button or changing flight modes and lowering the throttle.

Why Horizon Hobby champ s+ has reduced flight time?
- L
  Laura DouglasAug 14, 2025
  Reduced flight time or an underpowered Horizon Hobby Toy aircraft can occur due to a low flight battery charge. Fully recharge the flight battery. Ensure the propeller is installed correctly, with the numbers facing forward. A damaged or old flight battery can also cause this issue, so replace it as needed and follow the battery instructions. Cold flight conditions can also affect battery performance; ensure the battery is warm before use. Finally, the battery capacity might be too low for the flight conditions, so consider replacing it with a larger capacity battery.

  Stacy MezaAug 20, 2025
  If you're experiencing extra propeller noise or vibration with your Horizon Hobby Toy, the propeller, spinner, or motor might be unbalanced, causing excessive vibration. Try balancing these parts, or replace them if damaged. Another possible cause is a loose prop screw; make sure to tighten it.
