I will try to translate a bit,
The first guy interviewed is the runner of the club in the area of Paris. They do 1:8 and 1:10 RC since 1985 but this was the first mini-z race they ever organized, 4 more races are scheduled. That day, they had 96 drivers
so the timing was pretty tight. The track measures 27x27ft and the lanes are 3.3ft wide, lap lengh is 200ft.
They say that the track is OK for miniz racers but a little tight for F1 cars and they will adapt the layout for them in the future. The second guy explains the differences of the mini z compared to regular RC. He also insists on low price for the RTR kit but price can double if you go for special parts.
