5-Cylinder Radial Engine

5-Cylinder Radial Engine — 863 Piece Engine Building Set

Goqi (Goqi GQ3700) built 5-Cylinder Radial Engine as an engine meant for display, and the brick work reflects that. It runs to 863 pieces at 1:10 scale and takes around 2-4 hours to complete.

What Youre Building

The model is assembled as crankcase, rotating assembly and valvetrain, each finished as a separate unit before final assembly. Completed, it measures 22 cm x 25 cm x 8 cm (8.66 in x 9.84 in x 3.15 in). At 1:10, the proportions are set for display rather than play.

Inside the Box

863 ABS bricks with consistent clutch power, sorted into numbered bags. A printed manual guides the build step by step. Every brick is compatible with the major building systems, so parts from an existing collection drop straight in. If a piece is missing or damaged, our spare-parts guarantee covers the replacement.

The Build

Rated easy, this is an approachable build suited to builders new to sets of this size. Expect roughly 2-4 hours for a first pass at a steady pace. Working through the engine in stages keeps the bench manageable.

Display & Specifications

Finished, the engine sits best on a desk, where the moving internals are the point. Allow 22 cm of width for the footprint.
