Ascent GT PRO Z40 VTX digital video system, 5.8GHz, 1080P 60FPS, Avatar Pro V2 camera

Ascent GT PRO Z40 - a new generation digital FPV video system that combines the high-performance Ascent GT PRO VTX video transmitter with the Z40 dual-camera module. The system supports video transmission in 1080P resolution at 60 frames/s, providing high detail, minimal latency and a stable digital signal.

The camera is equipped with two sensors: a wide-angle for observation flight and a telephoto camera with variable magnification for detailed observation of distant objects. Switching and zoom control is carried out via the flight controller using MSP DisplayPort.

The video transmitter supports automatic and manual frequency selection, Canvas Mode OSD, integration with Betaflight, INAV and ArduPilot, as well as firmware updates via USB Type-C.

Due to the wide power range, compact dimensions and mounting holes of 20×20 mm and 25.5×25.5 mm, the system is easily integrated into FPV drones of various classes.
