SPECTRE is WUDFLY’s compact sub-250g digital FPV wing built for low, fast, close-range flying.

Developed from the TWIST_DT platform, SPECTRE takes that small, stable twin-motor airframe and rebuilds it around FPV. The camera, video system, electronics, wiring and removable wing structure are all integrated into the aircraft rather than added afterwards.

Light, agile and easy to throw in the car. Built for carving around trees, following terrain and making small spaces interesting.

Key specs:
• Around 215g all-up weight with the reference setup
• Sub-250g digital FPV aircraft
• Designed around DJI O4 Wide, with additional video-system support planned
• Twin-motor configuration with outward-rotating propellers
• Removable inner and outer wing sections
• Removable motor / leading-edge assemblies
• Built around INAV fixed-wing setup
• 3D-printable LW-PLA airframe
• Approximately 12 hours total print time for the reference airframe
• TPU elevon hinges integrated into the lightweight wing structure

What's included:
• SPECTRE 3D-printable STL files
• Complete printing and assembly guidance
• Full SPECTRE user manual covering print, build, wiring and configuration
• Recommended print settings and material guidance
• Reference wiring diagram and electronics layout
• INAV CLI reference setup for the supported flight-controller configuration
• Motor-direction, servo, receiver and ESC setup guidance
• Access to WUDFLY DEV LAB, the private builder Discord for support, updates, bug reports and sharing builds with other pilots

This is a digital aircraft package, not a physical kit.

You will need a 3D printer, the recommended electronics, basic soldering ability and normal FPV fixed-wing setup care. The aircraft has been designed around a defined electronics layout so component placement, wiring, CG and flight-controller setup are already worked into the package.

If you can build and configure an FPV drone, SPECTRE should feel familiar — just smaller, lighter and with wings.
