Why does the nose of my Horizon Hobby E-Flite HABU STS aircraft rise steeply at half throttle?
- V
  valerieadamsSep 1, 2025
  If your Horizon Hobby Toy aircraft's nose rises steeply at half throttle, several factors could be responsible. The wind may be too gusty or strong, so postpone flying until it calms down. The elevator might be trimmed 'up' too much; if trim adjustments exceed 4 clicks, adjust the push rod length. Also, the battery may not be installed in the correct position; move it forward approximately 1/2 inch.

Why does the trim change when I switch flight modes on my Horizon Hobby Toy?
- M
  Matthew BowenAug 30, 2025
  If the trim changes when you switch flight modes on your Horizon Hobby Toy, it could be due to the trim not being at neutral. If you need to adjust the trim more than 8 clicks, return the trim to neutral and manually adjust the clevis to center the trim. Also, avoid using Sub-Trim; instead, adjust the servo arm or the clevis.

What to do if my Horizon Hobby Toy aircraft will not connect to the transmitter after binding?

  Garrett DoughertyAug 29, 2025
  If your Horizon Hobby Toy aircraft will not connect to the transmitter after binding, there could be a few reasons. The transmitter might be too close to the aircraft during the connecting process; move the powered transmitter a few feet away, disconnect, and reconnect the battery to the aircraft. Interference from metal objects, wireless sources, or other transmitters could also be the issue; move the aircraft and transmitter to a different location and try connecting again. Ensure both the aircraft and transmitter batteries are adequately charged; replace or recharge them if needed. Lastly, the transmitter may have been bound to a different model using a different DSM Protocol; bind the aircraft to the transmitter.

  If your Horizon Hobby Toy aircraft will not bind to the transmitter, several factors could be the cause. First, the transmitter might be too close to the aircraft during the binding process; move the powered transmitter a few feet away, then disconnect and reconnect the battery to the aircraft. Another cause could be interference from a large metal object, wireless source, or another transmitter nearby; move the aircraft and transmitter to another location and try binding again. Lastly, ensure that both the flight battery and transmitter battery have sufficient charge; replace or recharge them if necessary.

Why does my Horizon Hobby E-Flite HABU STS aircraft keep turning in one direction?
- L
  Lauren CooleyAug 27, 2025
  If your Horizon Hobby Toy aircraft keeps turning in one direction, it may be due to incorrect rudder or aileron adjustments. Adjust the stick trims. Then, land the aircraft and manually adjust the aileron and/or rudder linkages to eliminate the need for transmitter trim.

Why is my Horizon Hobby E-Flite HABU STS Toy aircraft difficult to control?
- A
  Anna JeffersonAug 25, 2025
  If your Horizon Hobby Toy aircraft is difficult to control, it could be due to several factors. A wing or tail may be damaged and need replacement. A damaged rotor also affects control, so land immediately and replace it. Another cause might be the center of gravity being behind the recommended location; shift the battery forward and do not fly until the correct center of gravity is achieved.

Why is the flight time too short on my Horizon Hobby E-Flite HABU STS?
- J
  Jasmine ColeAug 23, 2025
  If the flight time of your Horizon Hobby Toy is too short, there are several potential causes. Ensure the battery is fully charged by recharging it. Avoid flying at full throttle for the entire flight; fly at just above half throttle to extend flying time. Also, consider the wind speed; it might be too fast for safe flight, so fly on a calmer day. Finally, inspect the rotor for damage and replace it if necessary.
