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 Bardwell’s 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 (don’t worry, that’ll buff out).

Specifications

• Processor: STM32F4 (because F7 would be overkill on a 65 mm whoop, calm down)
• 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 you’re about to drop on it)

What’s in the Box*

• 1× BetaFPV Cetus X Brushless Flight Controller
• 1× Pre-soldered PH2.0 or BT2.0 connector (depending on your kit)

Disclaimer

Box contents may differ, but the FC is always included — we’re not here to sell you empty PCBs. Yet.

Still Here?

If you’ve scrolled this far, you’re either an F4 spec nerd or just lonely — either way, the BetaFPV Cetus X brushless flight controller gives you solid whoop performance in a featherweight board. Add to cart, or keep pretending brushed motors are “retro cool.”
