Radiolink Pixhawk Flight Controller

Radiolink's version of the Pixhawk autopilot, with a reworked PCB layout and MS5611 barometer altitude hold for steadier flight at speed. It runs ArduPilot for multirotors, fixed-wings, helicopters and ground vehicles, and suits GPS quadcopters and hexacopters from F450 size up to survey and payload builds.
