Radiolink CrossRace Pro APM Flight Controller 37x37 with Gyro, Accelerometer, Barometer Built-in 5V&12V Dual BEC, Support 4-in-1 ESC and ESC Telemetry for Racing Drone, 2-8 Multi-Rotor

UPDATE: I've had this flight controller for a few months now, waiting for a Betaflight target to be released. Nothing ever showed on the support page, so I contacted ATA support. They responded with:I'm so sorry about it. The CrossRace Pro can set parameters by Radiolink Mission Planner, ArduPilot Mission Planner, and QGC Mission Planner. It can only upgrade the firmware from Radiolink and cannot upgrade the open-source firmware.It just has a fly experience of Betaflight(It has the ultimate flying feel, high-speed response and it is mainly manual operation), but it doesn't support the firmware of Betaflight.Not only this, but the Radiolink firmware only suports 5" quads! This is very deceiving advertising, bordering on fraud.And saying that APM flies like Betaflight is like saying a Peterbuilt corners like a Maserati.Worst part is this isn't even a good Flight controller. The pads are tiny and placed all over, and the heat sink gets in the way of wiring. The 4-1 esc connector only works on Radiolink ESC's and there are no pads to solder to for motor outputs 1-4. The connecter has to be repined with a new connecter or cut and soldered.Do not purchase this Flight Controller. You've been warned.

This is a full featured flight controller (FC) that has more features than a type FPV drone pilot needs. It comes with Ardupilot / Arducopter version 4.5.4 installed by default. And at the time of this review, there is no Betaflight 4.5 target available.All of the wiring harnesses you need are included, and it even comes with a piezo beeper and a USB A to USB C data cable.If you need a flight controller for your Ardupilot drone, I highly recommend this one.Pros:* Powerful STM32 H743 MCU* 12 PWM outputs for controlling motors and servos* Includes locking plugs for a solder-free or near solder-free experience.* Has solder pads and everything is well labeled* Ardupilot preinstalled* CNC aluminum heatsink* Well made, high quality PCB and soldered components* Dual BECs* Digital and analog VTX compatible, analog OSD built in* Built in barometerCons:* No public Betaflight or iNav targets available at time of review.
