ALTA X HD FPV System Overview

The HD FPV System for ALTA X is made up of four components:

Alta X HD FPV Camera Bay
Alta X Brain Bay
HD FPV Video Transmitter & Camera (MSP display port digital video systems with Canvas Mode)
Freefly Systems ALTA X

Key Benefits

Purpose-built integration for Freefly ALTA X
Real-time HD FPV with integrated flight telemetry
Designed for operational safety and pilot awareness
Stable, thermally managed performance for professional use
Internal, serviceable, and future-ready design
Developed and supported by XM2 Labs in Australia

Enhance your piloting with the ALTA X HD FPV System.

This upgrade transmits real-time status messages from the ALTA X flight controller through high-definition video to your HD FPV goggles or field monitor. The ever-improving HD FPV signal provides low-latency, sharp, and stable video, removing the graininess often seen in analog systems.

The ALTA X HD FPV system wirelessly transmits critical flight telemetry, including battery voltage, heading, and ground speed, via Status Messages to a compatible 2.4 GHz or 5.8 GHz receiver or monitor. Compatible with the DJI O4 Air Unit, Walksnail Avatar HD Pro V2, and other digital video systems with Canvas Mode and an MSP display port.

Additional PWM Outputs: Alta X Retractable Landing Gear Upgrade

The system includes three user-configurable PWM outputs integrated into the Brain Bay, offering versatile control options. We recommend connecting XM2's Retractable Landing Gear for the ALTA X to one of these PWM outputs. This setup enhances safety by allowing the Brain Bay to manage the landing gear’s functionality. Specifically, it prevents the Alta X landing gear from retracting while the drone is on the ground and enables the legs automatically lower during auto landings.

ALTA X HD FPV Camera Bay

The ALTA X HD FPV Camera Bay securely manages your HD FPV video transmitter and camera, enabling stable camera footage and active cooling for the device. You can adjust and lock the camera angle before takeoff. The design allows for easy installation of your camera and transmitter, and it fits directly into Bay 1 at the front of the ALTA X aircraft. It’s also been designed to be compatible with future digital VTX FPV camera systems.

ALTA X Brain Bay

The ALTA X Brain Bay serves as the core component of the HD FPV ecosystem, housing our MAVTx operating system developed by XM2 Labs. MAVTx facilitates seamless communication among the ALTA X flight controller, the Brain Bay, and the HD FPV Camera bay, granting users full access and control of the Digital OSD. Additionally, the Brain Bay features three user-configurable PWM outputs, seamlessly integrated for enhanced payload control options.

HD FPV Video Transmitter & Camera

Wirelessly transmit and receive high-definition video and essential flight telemetry: such as battery voltage, heading, and ground speed between the Alta X and compatible 2.4 GHz - 5.8 GHz transmitter / receiver.

Note: Power is required and not supplied.

ALTA X HD FPV System Power Compatibility (tested)

12V DC to DC Regulator for Alta (recommended)
Alternatively, connect the Brain Bay Power Input Cable (XT60 or XT30) to a 7.4V - 25.2V power source. Plug the JST-PH 2-pin connector into the Brain Bay power input.

Warning: The Brain Bay must be powered by a 2S-6S power source (7.4V - 25.2V). Connecting the Brain Bay to ALTA X flight packs will cause permanent damage to both the Brain Bay and HD VTX.

Available in Two Versions
