Here is a little video or the Top Races and the Chinese whip top.
We raced just before Mark had to leave for the airport so we did not have time to polish the racing technique. We did no have specific rules and we just ran a distance that would not make us sweat.
But it was enough to verify that it is a lot of fun.
For the Chinese whip I recommend raising the volume to the max to get a better idea of how it sounded.

On the last sequence you can see Mechtop together with Mark and SirBoot32.
