RTFhawk is an advanced autopilot system designed by the PX4 open-hardware project. It features advanced processor and sensor technology from ST Microelectronics® and a NuttX real-time operating system, delivering incredible performance, flexibility, and reliability for controlling any autonomous vehicle.

The benefits of the RTFhawk system include 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. These advanced capabilities ensure that there are no limitations to your autonomous vehicle. RTFhawk allows existing APM and PX4 operators to seamlessly transition to this system and lowers the barriers to entry for new users to participate in the exciting world of autonomous vehicles.

The flagship RTFhawk module will be accompanied by new peripheral options, including a digital airspeed sensor, support for an external multi-color LED indicator and an external magnetometer. All peripherals are automatically detected and configured.

Documentation and User Guides

Note: RTFhawk is a PPM-input autopilot, which means that it gets RC input from a single cable to the receiver, either via the PPM port, the Futaba S.BUS port, or the special satellite receiver port for Spektrum gear. Most modern RC receivers allow for PPM output, but some, such as non-S.BUS Futaba receivers, do not. If your receiver does not support PPM output, please add a PPM encoder boardoption to your order below.

RTFhawk includes:  Board ver. 2.4.5 no pbc changes from 2.4.3, just 4 cap values have changed. now come with backup battery Installed

all the boards will be solder / and updated for plug and play/ battery installed.

100% compatible with Pixhawk 1 to1. download all software from the main website. the normal mission plannner will update the board with no problems
