快X最齊 <- Yup but it doesn't mean they always have all parts of TCX...
But for me it is not a too big issue as i always online order parts for my RC car.
It is really much more easy to find parts for xray in HK.
From what I saw at RC tracks, Xray parts are much more durable than any other brand. And HPI parts are not that cheap.
For fun, I will vote for Xray. But, for serious racing driver, maybe TCX will perform better? if u don't really care about the cost of replacing parts....
