BetaFPV Cetus X Brushless Flight Controller

The BetaFPV Cetus X Flight Controller is the brain your whoop deserves F4 power, brushless motor support, and more acronyms than Joshua Bardwells inbox. Built for the Cetus X FPV Kit but just as happy in your franken-whoop, it gives you smooth, locked-in control without weighing you down. Translation: fewer failsafes, more laps around the living room.

Why You Want It

Because flying with a janky brushed board in 2025 is like running Windows XP in 2025 it technically works, but why would you? This FC brings the reliability of a proper brushless setup in a tiny package. Bonus points: plug-and-play design means you can spend less time soldering and more time crashing into your curtains (dont worry, thatll buff out).

• ESC: 4-in-1 brushless, 5 A continuous (BLHeli_S)
• Gyro: MPU6000 (the one everyone swears by)
• Firmware: BetaFlight compatible (no weird forks, promise)
• Weight: ~3 g (lighter than the solder blob youre about to drop on it)

Whats in the Box*

• 1 BetaFPV Cetus X Brushless Flight Controller
