Possibly not. It seems that this runs APM, which is an open source autopilot system. On their install pages, the Raspberry Pi is listed as a companion computer (presumably to be hooked to some other device that runs the code) (which this system might not do) but the Beaglebone Black (which I guess is similar to the Raspberry Pi, so might be what they do here) requires installation of realtime patches for Linux. This works by patching the Linux kernel to make almost all of it preemptable, (replacing spinlocks with mutexes) so interrupts can be acted on more quickly.
