He drives 1/10th scale for Team Pursuit....i think they don't have a 1/8th scale car, so he goes with Kyosho
Another example is Dario Balestri, he drives for Team Magic in 1/10th, and for Motonica in 1/8th

They had a 1/8th car long before the TC came out. He was running it at the CC. I guess he needed more speed for the worlds though
