The new Pixracer (formerly called XRacer) is available now and its fully supported by the Arducopter and PX4 community. Its a genuine open source project, already running with PX 4 stack software / QGroundControl (QGC), as well with Arducopter / Mission Planner (MP).
This is not just another small Pixhawk knock off or derivate, the Pixracer is the first autopilot of the new FMUv4 Pixhawk generation. Its coming with an upgraded Invensense Sensor generation (bye bye tricky LSM 303), a plug in Wifi board and last not least with a 2MB Flash : A real upgrade compared to former versions.
