LEGO Technic Race Jet Aircraft 42117

The LEGO Technic Race Jet Aircraft (42117) is a 2-in-1 building set that provides an introduction to engineering concepts. The primary model is a propeller-driven race plane with a functional mechanism linked to the wheels, causing the propeller to spin as the aircraft is moved forward. This design familiarizes builders with the gear systems characteristic of the LEGO Technic theme. The construction focuses on creating a sturdy frame and functional moving parts from the set's components, resulting in a model suitable for both display and active play.

This set's components can be reassembled into a secondary model, a jet aircraft, which offers a different building challenge and aesthetic. The jet model also incorporates moving parts, providing continued engagement after the initial build is complete. Printed instructions for the race plane are included, while digital 3D instructions for the jet aircraft are accessible through the LEGO Builder app. This dual-build capability allows for an extended construction process using the same collection of 154 pieces.
