The X-Racer flight controller has just been upgraded to the F4 processor. Let’s take a look at the features of this FC in this review.

The XRacer F303 has been one of the most solid FC’s out there, and FPVModel has upgraded the processor to an F4 for more processing power. The new XRacer F4 has very similar pin layout, features to the predecessor, but added OSD capability to it.

- STM32 F4 MCU with MPU6000 Gyro
- Supports Betaflight OSD
- 6 PWM outputs, allows hexacopter configuration
- Supports Frsky, Flysky as well as Spektrum receivers
It’s a simple FC that aims at those who don’t trust flight controllers with integrated PDB. However here are some of the things that you need to be aware of:
- The X-Racer F4 has built-in inverter for SBUS, but no built-in inversion for Smart Port – therefore “uninverted signal” hack is required if you want to run Smart Port
- It needs to be powered by 5V only, and cannot be powered directly by LiPo; which also mean you need to run a separate wire for VBAT
Too bad the motor pins are not at the four corners, which is a popular FC feature for easy and clean wiring.
Overall, I think the X-Racer F4 is designed for those who aren’t a fan of the popular AIO boards. It’s a plain simple board for simple setups where you don’t need all the fancy features. If you like the F3 version then you should definitely consider this new FC as replacement should be pretty straight-forward.
I am recently a bit busy but I should test this FC in a quad soon and report back.
