X-Racer F303 is a flight controller designed specifically for racing quadcopters. It is designed to work quickly and accurately with the pilot's stick movements. While maintaining a traditional form factor for this class of controller, it features a powerful computing system that allows your quadcopter to react instantly to changing environments. This is a controller you can trust. The only possible use for the controller is piloting racing quadcopters, as it doesn't have a barometer or magnetometer.
Features
8 output lines for connecting ESC and other hardware (like LEDs or squeakers)
Supports Sbus, SumH, SumD, Xbus, PPM and PWM receivers. We recommend using Sbus and PPM as these connection methods save a lot of weight due to the lack of a bunch of wires.
Built-in "black box" (flight recorder) for 16MB, where the controller can record data of all flights, even if you have flown more than a dozen times that day.
The use of a new generation of processors allowed to reduce the loop time (time of execution of one microcontroller cycle). This means that the controller monitors and reacts to changes in the situation even faster.
There is a separate output on the buzzer (buzzer) to search for a lost model.
Built-in sensor for on-board battery voltage.
Firmware
X-Racer F303 uses Cleanflight, a well-known open source firmware. Thanks to this, you can always find a lot of documentation and tips on how to customize this controller, as well as receive regular updates with new options and bug fixes.
The controller is also compatible with Betaflight firmware, which we recommend using. Whenflashing, select the file'spracingf3.hex'.

Attention!
Check the polarity! Very often, by accidentally confusing the polarity, people burn their controllers. Be very careful.
Have you checked the polarity? It's time to do it again. Plus to plus, minus to minus...
Make sure all the input channels are properly connected. Make sure you haven't mixed up the motor numbering. Otherwise you may have a very unpleasant mishap in flight.
