Care: Dust with a soft dry cloth and keep out of prolonged direct sun to protect the finish. Avoid moisture on the electrical components.

The pistons move. The BR0116 includes an L motor that drives the pistons up and down inside the transparent engine block. The motion is visible through the cover, and the gears rotate in sync. It's a fully interactive mechanical building set — not a static display.

No. The dynamic module requires 6× AAA (7号) batteries for the motor, sound, and spray functions. A 7号电池电源盒 is included, but the batteries themselves are not included — please supply your own. Check the manual for the exact battery type.

Clean water only — nothing else. Oils, fragrances, or chemicals can clog or damage the sprayer. Follow the manual for the fill level and don't run it dry.

The 4-speed switch lets you select between four speed settings for the piston movement. Turn the switch to change the pace — from a slow idle to a fast rev. It adds a layer of interactivity to the model.

Yes — the included sound module plays engine audio when the dynamic module is activated. The sound is synced with the piston motion for an immersive mechanical experience.

Mid-to-high difficulty — recommended for experienced builders aged 14+. The engine structure and dynamic module assembly are the most technically interesting parts. Numbered bags and a full-colour manual keep each phase manageable. Estimated build time is 6–10 hours.

Absolutely. The BR0116 is designed to look great as a display piece. The gold/silver/black colour scheme and transparent engine cover make it a striking addition to any desk, shelf, or workshop. It's both an interactive model and a collector build.
