About LEGO Bi-Wing

LEGO Bi-Wing (set #3502) is a small, compact build with 25 pieces from the Znap theme, released in 1998. The Znap line features snap-together flexible building system. This is a starter-level build suitable for ages 4+, with an estimated build time of 10-20 minutes. This set dates from the 1990s, a turbulent decade when LEGO launched Star Wars and Mindstorms while navigating financial difficulties.

Set Highlights

  • Compatible with all standard LEGO sets — bricks extend naturally into other sets you own.
  • Play-focused build with interactive elements designed for 4+ builders.
  • Classic-era set from 1998 — no longer in production and popular with collectors.

Build Tips

1

Check the piece count on the bag against the parts list before starting — knowing what you have prevents mid-build surprises.

2

Even in small sets, connection order matters. Follow the steps rather than building sections independently.

3

Keep the instruction booklet after building — it's the most reliable reference for disassembly, cleaning, or reassembly after storage.
