Lots of gossip here! If Boots was treated that bad, don't you think he would be on another team by now?
Of course we expected a better race from Kyosho at the 4wd worlds, but sh!t happens, Tebo had lots of breakages and bad luck (faulty ESC). 2 ZX-6 were on the B main. I don't know what happened to Boots, but 1/10th is not his prime class and the level of this race was huge.
I don't think you can have a definite opinion of a car on one of its first races, while in prototype stage, on such a hard and difficult track.
Maybe the "poor showing" is not a bad thing, now Kyosho does not have so much customer pressure for an early release of the ZX-6. Make it the best they can so we can enjoy a car on pair with the RB6

To be honest the ZX-5 is still awesome, I'm not sure I really "need" another 4wd!
