Six numbered bags deliver a brisk 30-45 minute build. A compact Technic spine locks in the front-wheel wishbones; System bricks then sculpt the skinny nose, side-pods and the RB20’s distinctive sloping fin, completed with two printed dark-blue wedges. Red Bull is the only car in the wave with a raised cockpit “scale plate” that the halo rests against, and a trans-yellow window piece cleverly doubles as the intake trim. New printed P-Zero slicks widen the stance, while a hinged halo and removable nose let you seat the driver or stage quick pit stops. Everything looks razor-sharp from shelf height, though some small panels are attached by just one or two studs, so vigorous play can send them flying.
