well guys, thx for all info.
I bought the car online (modellbau-seidel.de, delivery within 3 days!). It became a DB-01R.
The build was a breese (Tamiya-quality
) and as my son was not racing this weekend, I tried the car myself.
It was the stock setup, and on a full astroturf indoortrack so the setup was much too soft.
But with a little adjusting the car became very fun to drive.
It is just faboulous, knowing that you are competing with a plastic € 230,00-car againts much pricier carbon cars
