User Manual for Scorpion Tribunus 06-120A ESC

Quick Guide from the Manual

The Scorpion Tribunus 06-120A ESC is a high-performance electronic speed controller available in SBEC and OPTO versions. Before first use, you must perform a throttle range calibration. Always remove the propeller or pinion gear when working on the model with the battery connected to prevent accidental injury. The ESC uses Morse code via the motor to indicate status and errors.

Installation and Wiring

Refer to the wiring diagrams on page 3 for specific connections. Ensure battery polarity is correct (red to red, black to black). Solder quality connectors to the motor and battery wires. Mount the ESC with the heatsink facing outward, ensuring adequate airflow. If using zip ties, secure them around the metal heatsink, not the components.

Throttle Calibration

Throttle calibration is required before the first flight. Turn on your transmitter and set the throttle curve to 0% minimum and 100% maximum. Connect the battery, wait for the beep, then move the throttle to the lowest position. You will hear two beeps and a Morse code signal confirming calibration is stored.

PC and Android Configuration

The ESC can be configured via PC or Android using the Scorpion Sproto platform. Download the software from the official Scorpion website. You will need the Scorpion V-Link II cable and, for Android, an OTG cable. Always click the SAVE button after changing settings on any page to write the data to the ESC.

Helicopter Mode

This mode enables the internal governor. Key settings include Soft Start Acceleration (0-30% spool-up), Acceleration (30-100% spool-up), and Bailout Acceleration for autorotation recovery. Ensure you calibrate the throttle range before setting up the bailout switch.

Airplane Mode

Configure Drag Brake to control propeller behavior at 0% throttle. Adjust Throttle Acceleration based on aircraft size (e.g., 500ms for large planes, 350ms for smaller ones). Select PWM mode (Regular or Complimentary) based on whether regenerative braking is required.

Protection Settings

Configure safety limits to protect your equipment. Key parameters include Cutoff Delay, Minimum Voltage, Maximum Temperature, and Maximum Current. The ESC can also track Battery Max Capacity to trigger a power reduction when a set amount of capacity is consumed.

VBar Integration

The Tribunus ESC supports integration with Mikado VBar Control. Connect the slave cable to the RPM port of the VBar NEO. Ensure the latest firmware is installed on the ESC. Use the VBar Control manager to download the Scorpion ESC Support app to enable telemetry and setup features.

Anti-Spark DIY Kit

The included Anti-Spark kit helps prevent sparks when connecting high-voltage batteries. Follow the instructions on page 16 or 17 to solder the PTC resettable fuse to the positive wire and insulate it with the provided heat shrink.
