🟢 What Is BR10621?
BR10621 is a 3,861-piece 1:8 scale concept supercar in a rare vacuum-electroplated emerald green finish – a deep, lustrous metallic sheen that catches light with a jewel-like brilliance well beyond ordinary painted bricks. This track-inspired racer features a fully reproduced simulated V8 engine with rotating cooling fan blades that spin as the wheels roll, a detailed racing cockpit, and an open-armour display mode that lets you switch between a sleek racing configuration and an aggressive battle-style stance. Out of the box it's a static display – no batteries needed – with openable doors and hood. Its signature upgrade is a rear exhaust steam-smoke effect, unlocked with the separately sold RC Power Kit along with electric gullwing doors, an adjustable lifting chassis, LED headlights and RC driving. At 60 cm (23.6 in) long, it's a commanding centrepiece for any collection.
💨 Steam-Smoke Effect – The Signature Upgrade
The BR10621's headline feature is the rear exhaust steam-smoke system – with the separately sold RC Power Kit, the atomizers puff simulated white smoke from the twin rear exhausts, adding a dramatic visual dimension that sets this supercar apart from ordinary brick models.

⚠️ Safety & Care
⚠️ Product Information
Safety warning: Contains small parts – choking hazard. Not suitable for children under 14. Keep loose parts away from infants and toddlers. All bricks are made from non‑toxic ABS material intended for adult‑oriented model construction.
RC & atomizer note: Use clean water only in the atomizers – no oils, fragrances or commercial smoke fluid. Follow the wiring instructions and charge the battery packs under adult supervision.
Care: The electroplated emerald-green finish is chosen for its lustre – seat parts squarely rather than dragging them, dust with a soft dry cloth, and keep out of prolonged direct sun to protect the finish.
❓ Real Questions, Straight Answers
What builders ask before choosing this emerald green supercar.
“Does it smoke out of the box?”
No. The atomizers that create the steam-smoke effect come with the separately sold RC Power Kit, along with the motors, remotes and battery boxes. The standard set is a static display with the V8 engine, rotating fan blades and open-armour mode.
“How is the green different from a painted model?”
It's vacuum-electroplated, not painted – a custom metallic finish with a jewel-like lustre and depth that ordinary painted bricks simply cannot match. The emerald green shifts and catches light like a precious stone.
“Is the electroplated finish fragile?”
It's chosen for a durable lustre but it's still a coating – seat parts squarely rather than dragging them, dust with a soft dry cloth, and keep out of prolonged direct sun.
“What’s included in the RC Power Kit?”
The separately sold RC Power Kit includes motors, two 2.4G remotes, two atomizers, rechargeable battery boxes, LED lights and extension cables. It unlocks steam-smoke effect, electric gullwing doors, lifting chassis, open-armour mode, LED lights and RC driving. None of these parts are in the standard set.
“What does open-armour mode do?”
The open-armour mode lets you switch between a sleek racing configuration and an aggressive battle-style stance – the body panels reconfigure to reveal the mechanical structure underneath. It's built into the standard set, no kit required.
“Does the V8 engine's fan really spin?”
Yes. The V8 engine's cooling fan blades are mechanically linked to the wheels – when you roll the car, the fan spins in sync. It's a genuine mechanical feature that works on the static set with no batteries.
“How difficult is the build at 3,861 pieces?”
High difficulty – recommended for experienced builders aged 14+. The V8 engine with rotating fan blades, open-armour mechanism and detailed bodywork are the most technically rewarding parts. The numbered bags and full‑colour illustrated manual keep each phase manageable. Estimated build time is 16–24 hours.
“What if a piece is missing or damaged?”
Within 48 hours of delivery, send us a short unboxing video and clear photos to admin@brickroyal.com. We’ll replace any confirmed missing or damaged parts free of charge – no need to return the set. We want every builder to complete their supercar.
“Is it stable enough for a display shelf?”
Absolutely. The assembled model measures 60 × 27.5 × 16.5 cm – a substantial presence. The chassis is solid and rigid, built with ABS material and multiple cross‑locking structures, so it provides stable support during normal display. The wide track and low stance allow stable placement on any flat surface.
“How do I know which RC kit is compatible?”
The BR10621 RC Power Kit is designed specifically for this model. It includes all motors, remotes, atomizers, battery boxes, LED lights and cables needed. For custom setups, contact admin@brickroyal.com for compatibility guidance.
