What are trim switches?The trim switches are switch for adjusting center position of gimbal. Normally, two buttons for vertical adjustment and horizontal adjustment are installed near each gimbal. You can temporarily shift the center position of the gimbal by clicking it up / down or left / right.
With fixed-wing aircraft, the aircraft may be swept up, down, left, or right even if stick is in center position due to distortion of steering surface or misalignment of servo motor settings. Or, with multicopter, if horizontal calibration is not performed correctly, the aircraft may be swept. Trim switches are used to temporarily compensate for this problem.
And after the flight is over, you need to find out what caused the aircraft to be swept and make adjustments and reset the trim. Or if you can't solve the cause of the aircraft being swept, copy the trim settings to "Subtrim" field on OUTPUTS screen of "MODEL Menu" and reset the trim.
Effective range of trim settingsTrim switch settings are stored individually for each MODEL. Switching MODEL also switches trim switch setting. Furthermore, 9 types of " FLIGHT MODE " can be set for each MODEL, and trim switch settings are stored for each "FLIGHT MODE".
