Welcome to our Tech blog.

Today I will introduce a tiny UAV that is easy to build and fun to fly.

Model Information​

TThe Tiny Wing is a 3D-printable UAV with a 380 mm wingspan and a single pusher motor. Its name highlights the small form factor and lightweight design — just 100 g all up weight (AUW). The aerodynamics have been optimized for efficiency and agility.

  • Infill: 0%

Body:

  • Temperature: 220–250°C
  • Extrusion ratio: 0.6
  • Spiral vase mode: Off
  • Zero hopping
  • Avoid crossing perimeters during printing
  • Infill: 5% adaptive cubic

Assembly​

  1. Control surfaces

    • Cut out the aileron cutouts along the trailing edge.

    • Glue servo horn to aileron servo horn servo horn

  2. Wing Tip

    • Cut 1.75mm * 10mm printing wire glue to tip of wing, and glue wing tip
    • wing tip

  3. Servos and linkages

    • Mount the 2 g servos inside the fuselage pockets.

  5. Canopy

    • Insert 5×3 mm magnets into the canopy and fuselage slots. Drop on CA glue in before insert magnets
    • Ensuring correct polarity.

  1. Final checks
    • Verify CG (use the two dots under the fuselage as reference). For the maiden flight, it’s recommended to keep the CG slightly nose-heavy.
    • Ensure the ailerons move freely and in the correct direction.
