The flight controller that defines the future of drones

The first version of Fusion Engineering’s state-of-the-art flight controller—the Fusion Reflex—is the key to a new generation of drone flights. Designed with reliability and flexibility in mind, the Fusion Reflex is adaptable for any type of multirotor drone.

Aside from its light aluminium sleek design and powerful hardware, the real strength of the Reflex comes from the software. Written completely from the ground up in the Rust programming language and based on the latest research, Fusion Engineering’s flight control meets the needs of the commercial drone applications of the future.

The Fusion Reflex

The Fusion Reflex is perfect for drone manufacturers that work on drone applications for the future. We work hard every day to deliver you the finest state-of-the-art flight controller that will fit your design the best. User friendliness, safety and compliance are our top priority. Contact us now and get your hands on ground-breaking tech built from the ground up for the commercial drone market and designed for the future.


Three years in the making with the TU Delft Research Lab; testing with the Royal Netherlands Aerospace Centre (NLR). Built from the ground up for the commercial drone market. Fault-tolerant by design. No legacy systems to get in the way. Based on Rust programming language.

  • Fully functioning nonlinear INDI controller, including trajectory control
  • Compatible with QGroundControl and other software requiring MAVLink communication
  • Optimized data management system for easier data gathering and analysis
  • Flexible in drone lay-out: works with any multirotor configuration
  • Written in an isolated modular software architecture, significantly improving reliability

Future features of the Reflex include fault detection and fault-tolerant control, advanced state estimation, an improved user interface and much more.


Revolutionary tech, ahead of its time.
The Fusion Reflex is perfect for commercial drone companies that want to develop the next generation of drone solutions. We use the newest algorithms; facilitating the next generation of drone applications. Enter new markets and deploy for applications you didn’t consider possible.

Compliant with EU and US regulation.
Higher standards than currently required for granted Part 107 waivers. Designed to meet the EU requirements of SAIL 5 & 6, the highest risk mission classes for drones. This will make it possible to fly in places where it is not yet allowed right now.

Benefit today from more reliable and user-friendly software. Save time and costs by not having to worry about flight control. Installing it is easy: plug it in, set a few numbers and you’re good to go. No need for endless tinkering and tweaking. Still need some help? No worries, we offer full integration support.

A glimpse into the future

We are constantly improving our flight controller so you get the best quality. Therefore, our team will continue working on software updates. Here’s some of the new improvements you can expect.

Over the last months we implemented trajectory control and made UI and configuration improvements. Furthermore, we included triple GPS for heading support and did the implementation of our unique INDI based flight control. Additionally, fault detection and fault tolerant control will be implemented over the coming months.
