BetaFPV Matrix 1S Brushless Flight Controller (3IN1/4IN1)

The Matrix 1S Brushless Flight Controller redefines 1S whoop performance with two purpose-driven architectures: the 3IN1 for DJI O4 digital dominance (integrating FC, ESC, and ELRS 2.4G RX while omitting analog OSD), and the 4IN1 for analog mastery (adding built-in OSD + solder pads for external VTXs). Both feature the iconic cross-design architecture, newly developed BEC, 18A peak ESCs, and the STM32G473 MCU for 55% faster processing—delivering effortless setup, pro-tier control, and uncompromised flight dynamics that rewrite 1S standards.

Attention

Crafted for newcomers and recreational pilots, the Matrix FC features a robust 1mm board for enhanced durability, a solder-free design for easy installation, and a beginner-friendly experience. For advanced pilots, the ultra-thin and lightweight Air FC is the definitive choice, engineered with race-winning agility to push the boundaries of FPV flight performance.
Flight controllers are covered for manufacturer defects. Issues arising from user errors, physical crash damage, damage during installation or dismantling, modifications, power surges, electrical fires, or water exposure are not covered.

Bullet Points
