Additionally, it supports Betaflight Configurator, a popular application for customizing and fine-tuning RC aircraft.

Key advantages of the BetaFPV Cetus X

Premier Choice for the Next Level

The quadcopter delivers impressive speeds and rapid throttle response thanks to its robust 2S powerplant, making it an excellent option for beginners advancing their skills.

ExpressLRS 2.4G System

Available with a built-in ExpressLRS 2.4G receiver—the most popular radio link known for ultra-low latency and excellent control range—allowing pilots to fly indoors or confidently explore outdoor landscapes.

Upgraded Video Transmission

Outfitted with an adjustable 25–400mW M04 VTX and a C04 FPV camera (based on Caddx Nano Ant or Runcam Nano 4), ensuring better image quality and signal stability over longer distances compared to C02 cameras.

Betaflight Customization Support

With full support for the Betaflight Configurator, pilots can learn how to calibrate the accelerometer, customize the On-Screen Display (OSD), manage VTX settings, and gain essential hands-on experience with flight controller setups.

Durable 360° Frame Protection

Inheriting the classic white aesthetics of the Cetus series, the frame is constructed from rugged PA12 material for superior impact resistance. Full 360° guards protect the props during indoor and outdoor training, while the camera tilt adjusts from 0° to 40° to suit your flight speed.
