# DroPix Flight Controller
PX4 does not manufacture this (or any) autopilot. Contact the [manufacturer](https://store.drotek.com/) for hardware support or compliance issues.
The DroPix system includes integrated multithreading, a Unix/Linux-like programming environment, completely new autopilot functions such as Lua scripting of missions and flight behavior, and a custom PX4 driver layer ensuring tight timing across all processes.
This flight controller is manufacturer supported.
