Why is my Horizon Hobby E-FLITE Slow Ultra Stick 1.2m Aircrafts oscillating?
- G
  Grant ValentineJul 29, 2025
  If your Horizon Hobby Aircrafts experience oscillation, several factors could be responsible. A damaged or imbalanced propeller or spinner can cause this issue, so replace the propeller or spinner, or balance the propeller. Motor vibration can also lead to oscillation; in this case, replace parts or correctly align all parts and tighten fasteners as needed. Other potential causes include a loose receiver (align and secure it in the fuselage), loose aircraft controls (tighten or secure the servo, arm, clevis, horn, and control surface), worn parts (replace worn parts, especially the propeller, spinner, or servo), or irregular servo movement (replace the servo).

What to do if my Horizon Hobby E-FLITE Slow Ultra Stick 1.2m has inconsistent flight performance?
- S
  Samuel TurnerAug 12, 2025
  Inconsistent flight performance in Horizon Hobby Aircrafts can stem from a few key issues. First, ensure that the trim is at neutral. If you adjust the trim more than 8 clicks, adjust the clevis to remove trim. Second, verify that Sub-Trim is not in use, as it is not allowed; instead, adjust the servo linkage. Finally, make sure the aircraft remains immobile for 5 seconds after connecting the battery with the throttle stick in the lowest position. Disconnect and reconnect the battery, keeping the aircraft still for 5 seconds.
