      Note: Pilots who have LiteRadio 2 SE in Cetus or Cetus Pro FPV Kit can bind and fly the Cetus X Cetus FC version.

      Auxiliary Flight Function

      Built-in highly precise barometer to detect the height, the version with Cetus FC benefits from great stability due to its position hold mode, and auto-hovering, which enables the drone to stay at the current height. This function also ensures an emergency landing of the drone whenever loses control or is on low battery. Meanwhile, its stable flight allows you to catch the best footage with the FPV Goggles. It really does an immense amount of fun and ease of flight for all pilots. Recommend flying it with BETAFPV VR03 Goggles.

      Powered by 2S, Cetus X has loads of punch and speed, making it smoother and more suitable for outdoor practice, great for the next level. For indoor practice, the Cetus Pro with 1S power, which has the same auxiliary flight function, is easier for initial pilots to control and fly.

      Note: The position hold function is only available in N mode.

      Improved Video Transmission

      Cetus X Brushless Quadcopter comes with M04 25-400mW VTX and C04 FPV camera. The VTX features a lightweight and adjustable output power for longer distance flying. Combining this VTX and the excellent radio link ExpressLRS 2.4G/Frsky D8, pilots can fly whoop drones longer to explore more possibilities and have fun. In addition, C04 FPV camera (based on Caddx Nano Ant Camera/Runcam Nano 4) shows better quality in FPV flight compared with C02 FPV camera.

      Powerful Propulsion System

      Equipped with 1103 11000KV Brushless Motor and Gemfan 2020 4-blade props. 1103 motors are designed for 2S quadcopters with incredible power, smooth and quiet operation, and light enough. Besides, Cetus X quadcopter adopts 2020 4-blade props, which are lighter and durable enough, offering pilots a high-efficiency flight experience.

      Primary Choice for Next Level

      Cetus X Brushless Qaducopter Betaflight FC version supports configuring on Betaflight configurator. It is a primary choice for beginners who start to learn drone configuring, which helps beginners to get advanced level. With the Betaflight configurator, you can calibrate accelerometer, custom OSD content, adjust the video transmitter and etc.

      Note: Please DO NOT configure ESC or Motor settings on Betaflight configurator.

      Betaflight Flight Controller

      Cetus X brushless quadcopter is built-in F4 2S 15A V1.0 FC, supporting ELRS 2.4G protocol. The ELRS 2.4G version comes with betaflight 4.3.1 FC firmware so it supports ELRS V2.0. The ESC on the new board powered by BB51 hardware comes with Bluejay 48k ESC firmware, allowing 1103 11000KV motors to give full play to the efficiency of power. We update the gyro to BOSH BMI270 for better performance and stability since the new F4 2S 15A V1.0 FC.

      For Cetus X ELRS 2.4G version, the Betaflight firmware 4.3.0 and up start to support BMI270 gyro. For Frsky D8 version, we recommend using BETAFPVF411RX 4.2.11 firmware and CLI dump file offered by BETAFPV. 

      The default flight controller firmware enables bidirectional D-shot and is compatible with Bluejay ESC firmware. If you update the 4.3.0 and up firmware for ELRS 2.4G from the Betaflight official site, please flash the CLI dump file for Cetus X.

      Download the firmware and CLI dump file for Cetus X ELRS 2.4G or Frsky.

      The Bluejay firmware could support the BB51 hardware now. Both ELRS and Frsky boards are powered by BB51 hardware. If you want to setup the ESC specification, please use the BLHeliSuite16714902A_Beta or ESC-Configurator.

      Note: Only ELRS 2.4G version supports motor direction set through Betaflight Configurator and SPI Frsky version does not support it. BLHeli Configurator and Bluejay Configurator are invalid for the BB51 ESC (both versions).

      Good beginner drone, possibility to update to ELRS 3

      After leaving negative review on the Cetus X kit I want to be honest and also talk about the positive.

      The drone is good. Especially for beginners. I've only used it over grass so I can't talk about how resistant to crash it but it should be. Otherwise it works, is easy to bind, configurable using Betaflight, can be updated to ELRS 3 to use on any radio. I did update it and it works perfectly. Also two sets of batteries are included, a charger, props, screwdriver, USB C adapter. You don't need anything else to make it wok. Even if in the future you may want more batteries and a charger with more slots and a storage mode (charging/discharging battery to 3.8V to avoid wear during long storage).

      I only wish it was sold with the 550mAh. I only get 3 minutes of flight time with the 450mAh, a bit short.

      EDIT: since then I've noticed that betafpv only published this review as it was positive and deleted the others. The review website shows that only 30% of reviews are published by betafpv, now you know how reliable they are..


      Absolutely delighted with the purchase, customer service was faultless 👌🏻

      Cetus X

      Fast delivery.
      Easy update firmware and conect to radio - not betafpv.
