Bongi,

Try to find out where they race 1/8th off road. A decent model shop should be able to tell you or you can try one of the guys selling stuff on Taobao (Chinese kind of Ebay).

The guys from RCinPRC (I saw the message there to) may be able to help. There is an off road track here in Guangzhou so there should be something in Shanghai as well....... If not, find some land and get some workers to make you one... lol

I've been out of China and RC for awhile but keen to get back into in in the next year if possible.

Good Luck
