Each year when I was 8/14 years old, I built 3 or 4 F1 for playing at race car. It was better than play with real 1/24 or 1/43 models because i could change the wheels, install a driver, restore the car after a crash and reconfigure the car each years.
Now i continue to build F1 each years and my sons are playing with these. I try to respect the details and the differences between the differents cars (see the wings and the noses) as well as possible. I try to have new idea for building realistic cars. My sons particularly appreciate to change the "camera", black or yellow, which is the difference between the two cars of a team.
A set could include one car or several cars with a driver and two "cameras" for each car and maybe a podium and pits...
