The UAV was designed using SolidWorks 2023 and Blender3D, as shown in Fig. 1. The vehicle
features a modular structure, allowing for easy disassembly and transportation. Its wings, fuselage,
tail, and rudders can be individually detached. The frame was constructed using carbon fiber rods
and plywood, with the plywood components cut into shape using a laser cutter. All mounting parts
were 3D-printed using PLA, while the outer surface was made from Depron sheets.
The initial version of the UAV encountered several design issues, which were addressed before its
test flight (Fig. 2). The vehicle successfully took off in both stabilize and GPS-guided modes,
reaching an altitude of approximately 30 meters in VTOL mode. It then transitioned smoothly into
fixed-wing flight and landed in VTOL mode (video). The total flight time was about 5 minutes,
entirely in VTOL mode.
