Firmware Upgrade - Zerotech YS-S4 User Manual

YS-S4 Multi-rotor Autopilot User Manual V1.4
You will need a TX with at least 7 channels to use the Gimbal function. Use channel 7 on your transmitter for
gimbal control and assign it to a knob switch, Channel 7 will now adjust your gimbal pitch location and will
continue to stabilize the camera at all angles of pitch. The spare channels may be used for other applications.
Normally roll servos will maintain gimbal stabilization in the middle position. If your gimbal tilts to one side it can
be adjusted it by clicking "Enter Setup" in the Setting section (CH5 must in manual and the throttle set to
minimum) Now the CH7 knob can be used for controlling gimbal roll. The gimbal roll's balance position may be
fixed and saved by clicking "Quit Setup". Now CH7 will revert to controlling gimbal pitch.
