X-Racer F303 Flight Controller
This board has everything you need, and nothing you don't. The board's layout and functions are tailored only to fpv racers and acro fliers, which results in a durable and low-cost, yet extremely effective flight controller for your next build.
The gyro is precise and the board is reliable. When other boards toast or stop working for no reason, this board will continue working hard for you and your quad. XRacer F303 V3.1 Flight Controller SPI boasts an updated and more accurate gyro over previous versions, able to run high refresh rates while still keeping up with the complex calculations which you demand.
The board’s layout makes it easy to setup and get running, and the provided wiring diagram (shown below), means you can get your board going on the very first try. When others are down for repairs, you’ll stay in the air. Give this flight controller a try, you’ll be glad you did.
Use the firmware titled "X_RACERSPI" on Betaflight.
