Built in high capacity black box featuring 16mb flash memory. This will allow you to store an entire days worth of flights while you are out in the field burning through multiple batteries and flights. Next generation F3 processor for efficient flight calculations and those lower loop time youve been reading about.
The size of the flight controller follows the form thats so typical in all the others allowing you to mount to the majority of the frames out on the market without the need of changing mounting holes on most base plates.
8 PWM I/0 lines for ESCs and added options you may choose.
Supports Sbus, SumH, SumD, Xbus, PPM, PWM recievers but has a recommended and weight saving direct connection specifically for Sbus, which is our recommended connection for flight control.
Buzzer port for audible lost model location.
Convienent pin outs for easy, reliable soldering.
Only available in Acro style, no barometer or magnetometer.
The X-Racer flight controller runs on the open source Cleanflight software and its compatible with the Boris B. Betaflight firmware. The hex file to use is spracingf3 hex.
Failure to adhere to these warnings will void your warranty and destroy your flight controller.
Observe polarity at all times. Double check all connections before applying power. It is very common for users to accidentally reverse polarity, try not to let it happen to you.
After double checking all connections its a good idea to triple check connections...positive to positive, negative to negative. Make certain all channel inputs match corresponding outputs or else undesired flight characteristics will happen.
Keep magnets away from flight controller.

#1 Choice for Serious Racers
The X-Racer F303 flight controller was designed for the serious racer. We have followed the idea of simplicity and kept the basic rugged design of servo style pinouts so you do not have to worry about the fragility of plastic connectors in a crash.
This X-Racer flight controller only comes in one version...ACRO! This is not a flight controller that is designed to fit the needs of everyone, it is a flight controller designed to fit the needs of racers and free style flyers.
The X-Racer is backed by the reputation of FPV Model giving you a flight controller that you can trust.
Differences Between V2.1 and V3.1:
V2.1 uses MPU6050 with I2C & spRacingf3 firmware.
V3.1 uses MPU6000 with SPI & X_RACERSPI firmware. DSHOT compatible!!!
V3.1: The newest version of the X-RACER F303 is Version 3.1. We have listened to your requests for SPI and we have changed the MPU 6050 over to MPU 6000 in order to give you those faster loop times that you have been asking for. We have tried to keep the changes minimal with this and have left all of the previous changes that many requested the same. This board still comes with the through holes for Vbat, RSSI, and the buzzer. It also comes with the dedicated SBUS and RGB LED connections. X-Racer is designed for racers and acro pilots so we keep the design simple and durable. Have fun with it!

Rc-toys Multi Rotor safty Tip Keep your PROPS OFF not installed until you are fully conversant/understand in full the functions of your Tx in full including TRAV (end Points), the arm and disarm procedures - realise that for a noob skiping or out-of-order set-up steps or moving sticks, or even static - PROPS may start at anytime without warning. Never install props prior to calibration of the ESC and testing the gyro orientation, and arm/disarm testing of the board - YOU are responsible - make sure your actions and your Copter is safe. Never ASSUME the props will not start - removing the props removes the risk.
