HI Renjie,

Just got back from China. Did not have much time for RC but I went to the shop in Beijing. They have pretty good inventory down there. I have asked them if I can go to race track but unfortunately they was not planning that evening. Here is the contact number for that RC car store guy: 13801396637 (cell), 64207706. He does not speak almost not english. They had pretty good cars down there. I bought Futaba 4PK 2.4 for 360$.

Regards,

Narra
