Matrix 1S Brushless Flight Controller|G4 4IN1

Matrix 1S Brushless Flight Controller (4IN1 Version)

The Matrix 1S Brushless Flight Controller is designed to redefine 1S whoop performance. This page introduces the 4IN1 version (analog-focused) only.

The 4IN1 version integrates FC and ESC with a built-in OSD and provides solder pads for an external VTX, delivering excellent flexibility for analog setups. Featuring the iconic cross-design architecture, a newly developed BEC, 12A continuous / 18A peak ESC, and the STM32G473 MCU with 55% faster processing than F411, it offers easy setup, professional-grade control, and uncompromised flight dynamics for modern 1S whoops.

Attention

The Matrix FC is crafted for newcomers and recreational pilots. Its robust 1mm-thick PCB enhances durability, and the beginner-friendly design makes installation and operation simple.

For advanced pilots seeking ultra-light weight and race-winning agility, the Air FC is the definitive choice, engineered to push the limits of FPV flight performance.

Flight controllers are covered for manufacturer defects only. Damage caused by user error, crashes, installation or removal, modifications, power surges, electrical fires, or water exposure is not covered.
