    Why does the trim change when flight mode is switched on my Spektrum AR635 Remote Control?
    • A

      If the trim changes when the flight mode is switched on your Spektrum Remote Control, it's likely because the trim or sub-trim isn't at neutral. If you adjust trim more than 8 clicks, adjust the clevis to remove trim. No Sub-trim is allowed. Adjust the servo arm or the clevis.

      When the flight mode is switched on your Spektrum Remote Control, a trim change can occur if the trim isn't at neutral. If you've adjusted the trim by more than 8 clicks, adjust the clevis to remove trim. Also, sub-trim is not allowed; instead, adjust the servo arm or the clevis to ensure proper neutral positioning.

    Why does my Spektrum AR635 oscillate?
    • B
      Brian CantrellAug 6, 2025
      If your Spektrum Remote Control exhibits oscillation, it could be due to several factors. You might be flying over the recommended airspeed in 3D mode; if so, switch to GF mode. Other potential causes include a damaged or imbalanced propeller (replace or balance it), motor vibration (replace parts or correctly align/tighten fasteners), a loose receiver (align and secure it), or loose aircraft controls (tighten or secure servo, arm, linkage, horn, and control surface). Flight condition variations may also contribute; adjust gain accordingly. Worn parts or irregular servo rotation may require gain adjustments, parts replacement, or servo replacement. Ensure the correct transmitter type is assigned in the receiver. If oscillation persists, decrease gain.

    What to do if my Spektrum Remote Control has incorrect response to the AS3X Control Direction Test?

      Laura BennettAug 11, 2025
      If your Spektrum Remote Control gives an incorrect response to the AS3X Control Direction Test, it is due to incorrect direction settings in the receiver. In this case, DO NOT fly. Correct the direction settings (refer to the receiver manual), then fly.

      Keith KlineAug 21, 2025
      If you observe an incorrect response during the AS3X Control Direction Test with your Spektrum Remote Control, **DO NOT fly** the model. This issue arises from incorrect direction settings in the receiver, which could lead to a crash. To resolve this, correct the direction settings by referring to the receiver manual before attempting to fly.

      Natalie SmithNov 15, 2025
      If your Spektrum Remote Control exhibits oscillation, several factors could be at play. First, if you're flying over the recommended airspeed in 3D mode, switch to GF mode. Other potential causes include a damaged or imbalanced propeller (replace or balance it accordingly), motor vibration (replace parts or correctly align/tighten fasteners), a loose receiver (align and secure it), or loose aircraft controls (tighten or secure servo, arm, linkage, horn, and control surface). Flight condition variations may also be a factor; adjust the gain to suit current conditions like wind, updrafts, altitude, humidity, and temperature. Worn parts, especially the propeller, pivot points, or servo, can also cause oscillation, so adjust the gain or replace these parts. Irregular servo rotation necessitate...
