    *Acknowledgements: AlienWhoop V2.1 is inspired by AlienFlight F3 Quad Brushed V1

    ** Back by popular demand we've refined the V2 with Blackbox, dedicated FrSky SBUS signal inverter, more UARTs, and easier to solder pads for the external receiver.


    • Quick reference diagrams of board layout and functionality
    • Pre-build suggestions and Pro-Tips
      • Plan your build
      • Know in advance which pads you need before you solder
    • Basic build guide for the novice and pro alike
    • Firmware and settings
      • Note: It's important to try the stock settings, especially the PIDs and filters. They have been carefully selected to meet the challenge of optimizing whoop flight. Deviating from the suggested settings can cause unexpected flight behavior or fly-aways.

    We'd love to participate in your build process. Join us on Discord to hang out and pick up tips from other pilots as you build and configure your AlienWhoop. Building alone can be very frustrating and confusing so do yourself a favor and join the community.
