WIY Strila Replica

A non-flying display replica of the WIY Strila — a Ukrainian interceptor drone built as a slim "tail-sitter" quadcopter, with four motors on swept X-wings, a nose sensor, a side pitot boom and a red tail pull-ring. This is a decorative scale model only: it doesn't fly and has no electronics or functional parts.

Designed from reference photos as a parametric model, and sized for easy desktop printing.

✨ Highlights

• Accurate detailing — 4-window ogive motor nacelles, panel screws, section seam lines, belly payload box, side fin, nose cameras and the red tail ring.
• Four propellers that actually spin — they snap onto the motor axles with no glue, so they stay free to turn.
• Glue-together build — clean flat and keyed joints, no screws or hardware of any kind.
• Easy to print — most parts lay flat; only the motor cones want a little support.

🖨️ Printing

• Files are sized as a desk-friendly display: ~310 mm long (about 180 mm across). Want the real-life full size? Just scale to 200% → 620 mm — or scale to taste.
• 17 printed parts: body in 3 sections, plus 4× wing, 4× motor, 4× propeller, the nose probe and the tail ring.
• Suggested colours: dark grey fuselage, black/dark motors, red tail ring (a single colour prints fine too).

🔧 Assembly

Glue is the only thing you need (CA / super glue). Print, clean up any supports, then:

1. Glue the three body sections into one fuselage.
2. Slot each wing into the body, and a motor onto each wing tip.
3. Peg in the nose probe and the tail ring.
4. Snap the propellers onto the motor axles — do not glue these so they keep spinning.

A full step-by-step assembly guide is included.
