# 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 Drotek® DroPix autopilot is based on the Pixhawk®-project (opens new window) FMUv2 open hardware design. It runs the PX4 Flight Stack on the NuttX (opens new window) OS.

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.
