I'm a lucky guy living in Thailand, few minutes away from where the next Worlds will be held.
Many official teams have been here already. Hotbodies, Xray (last day today), Kyosho, Yokomo and Tamiya ran several days of private testing on the Bangkok RCS track. Believe me, all the great drivers on Earth will attend for sure.
Hara is now 1/8 GP Buggy World Champion, I'm pretty sure he can be ISTC Worlds Champion this year too...
