Two of my friends have purchased the 4 car sets of LXX Char G cars. By our testing, it appears that the LXX numbers correspond to the Bit Char G frequencies as follows:
LXX 01 - 27 mhz
LXX 02 - 35 mhz
LXX 03 - 45 mhz
LXX 04 - 57 mhz
Funny thing, however, the LXX 27 mhz (01) controller seems to control both 27 and 57 mhz cars (bits). We are completely at a loss to explain this phenomenon, however.
