The X4 SC is not a full size SC truck, more like 3/4. I think its daft of Ansmann to market them as SC trucks when they are clearly to small.
They also come with some odd wheels, i had to buy 2.2/3 wheels and tyres to go on mine, still never raced it as it was not usual size

Ended up getting a CORE as this is the proper SC size and comes wiht the right wheels
