Actuators / Motors (PX4)

The Actuators page provides a unified interface for configuring motor and servo outputs on PX4 vehicles (PX4 v1.13+).

Geometry / Mixer

The top section displays the vehicle's actuator geometry, dynamically generated from the mixer configuration. For multirotor vehicles, an SVG diagram shows motor positions — you can click individual motors to select them. Each actuator channel has configurable parameters such as position offsets and tilt angles.

Actuator Outputs

The right panel shows all output channels with:

• Function — assign each output to a motor, servo, or other function
• Min / Max — PWM or DShot output range limits
• Failsafe — output value when failsafe is triggered
• Disarmed — output value when the vehicle is disarmed

Actuator Testing

WARNING

Remove all propellers before testing actuators.

With the safety switch toggled, individual actuator sliders appear for testing each channel. An optional All Motors slider allows spinning all motors simultaneously at low throttle for verification.

Actuator Actions

Dynamic action buttons (e.g., beep, identify, 3D mode) are shown based on the vehicle's actuator configuration. The motor identification feature spins motors one at a time to verify correct wiring and rotation direction.
