Why Horizon Hobby E-flite Twin Otter 1.2m aircraft will not bind to transmitter?
- A
  Amy DawsonAug 17, 2025
  If your Horizon Hobby Toy aircraft won't bind to the transmitter, there are several potential causes. First, the transmitter might be too close to the aircraft during binding; move it a few feet away, then disconnect and reconnect the flight battery. Alternatively, large metal objects or wireless sources could be interfering; relocate to another area and try again. Ensure the bind plug is correctly installed in the bind port. A low battery in either the aircraft or transmitter can also prevent binding, so replace or recharge them. Finally, make sure you hold the bind switch or button long enough during the bind process; power off the transmitter and repeat the process, holding the button until the receiver is bound.

Why is my Horizon Hobby Toy aircraft flight time reduced?
- A
  Abigail WilsonAug 20, 2025
  If your Horizon Hobby Toy aircraft has reduced flight time or seems underpowered, it could be due to several reasons. First, ensure your flight battery is fully charged. A backwards-installed propeller can also cause this issue; make sure the numbers face forward. A damaged flight battery should be replaced, following all battery instructions. Cold flight conditions can also affect performance, so warm the battery before use. Lastly, the battery capacity might be too low for the flight conditions, in which case you should replace it with a larger capacity battery.

What to do if Horizon Hobby E-flite Twin Otter 1.2m aircraft will not respond to throttle?
- K
  Kenneth WhiteAug 26, 2025
  If your Horizon Hobby Toy aircraft responds to other controls but not to the throttle, ensure that the throttle stick is at idle and the throttle trim is at the lowest setting. Verify that the throttle servo travel is 100% or greater. Check if the throttle channel is reversed and, if so, reverse it on the transmitter. Finally, confirm that the motor is securely connected to the ESC.

How to fix oscillation in Horizon Hobby E-flite Twin Otter 1.2m aircraft?
- L
  Luis FletcherAug 28, 2025
  If your Horizon Hobby Toy aircraft is experiencing oscillation, it could be due to several factors. A damaged propeller or spinner can cause this, so replace them if necessary. An imbalanced propeller should be balanced. Motor vibration can also lead to oscillation; replace parts or correctly align them, tightening fasteners as needed. A loose receiver should be aligned and secured in the fuselage. Loose aircraft controls should be tightened or secured (servo, arm, linkage, horn, and control surface). Worn parts, especially the propeller, spinner, or servo, should be replaced. Finally, irregular servo movement can cause oscillation, so replace the servo if needed.

Why is my Horizon Hobby E-flite Twin Otter 1.2m propeller making extra noise?
- D
  Dustin CarterAug 31, 2025
  If your Horizon Hobby Toy aircraft is making extra propeller noise or vibrating excessively, it might be due to damaged propeller, spinner, collet, or motor; replace any damaged parts. An out-of-balance propeller can also cause this issue, so balance or replace it. Finally, check if the prop nut is too loose and tighten it if necessary.

What to do if Horizon Hobby E-flite Twin Otter 1.2m control surface does not move?
- P
  perezwilliamSep 3, 2025
  If a control surface on your Horizon Hobby Toy aircraft isn't moving, check for damage to the control surface, control horn, linkage, or servo, and replace or repair any damaged parts, adjusting controls as needed. Inspect wires and connections for damage or looseness, connecting or replacing them as necessary. Ensure the transmitter is correctly bound or that the correct airplane is selected in the transmitter. A low flight battery charge can also cause this, so fully recharge it. Lastly, a damaged BEC (Battery Elimination Circuit) of the ESC might be the issue, requiring ESC replacement.

Why does Horizon Hobby E-flite Twin Otter 1.2m Toy motor power pulse and lose power?
- S
  Sandra MossSep 5, 2025
  If your Horizon Hobby Toy aircraft motor power pulses and then loses power, it could be due to several reasons. The ESC might be using the 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 postpone the flight until it's warmer. An old, worn-out, or damaged battery should be replaced. Finally, the battery C rating might be too small, so use the recommended battery.

Why does my Horizon Hobby Toy have inconsistent flight performance?
- E
  Erin JonesSep 8, 2025
  If your Horizon Hobby Toy aircraft is showing inconsistent flight performance, check that the trim is at neutral. If you adjust trim more than 8 clicks, adjust the clevis to remove trim. Ensure that Sub-Trim is not used; adjust the servo linkage instead. Also, after connecting the battery, keep the aircraft immobile for 5 seconds with the throttle stick in the lowest position. Disconnect and reconnect the battery, then keep the aircraft still for 5 seconds.

Why are the controls reversed on my Horizon Hobby E-flite Twin Otter 1.2m aircraft?
- H
  hperezSep 12, 2025
  If the controls on your Horizon Hobby Toy aircraft are reversed, the transmitter settings may be the cause. Perform the Control Direction Test and adjust the transmitter controls appropriately.

What to do if Horizon Hobby E-flite Twin Otter 1.2m Toy AS3X Control Direction Test shows incorrect response?
- A
  albert83Sep 14, 2025
  If the AS3X Control Direction Test shows an incorrect response on your Horizon Hobby Toy aircraft, do not fly. The direction settings in the receiver are incorrect, which can cause a crash. Correct the direction settings (refer to the receiver manual), then fly.
