In recent years, I had dropped the Technic collection because I was a bit fed up trucks. And here comes that this fantastic race car, beautifully designed and full of punch, a real treat for design and engine. The assembly starts with the multiple gears which will actuate the moving parts. Be careful to avoid mistakes, because the construction is really delicate, and I had to disassemble several parts where I had not read the plan. It connects the interior fittings (seats, engine and pistons, 4-wheel suspensions), then the body formed of solid parts and of "holes". Finally, the engine allows, via a lever instead of the gearbox, opening and closing the hood, both doors separately, and out the rear wing. Some stickers (not essential) come decorate the solid parts. The front wheels are directional course. Note the presence of numerous new pieces. This car will remain for sure in the annals!
