very nice conversion man,
what motor is that in the CEN? ... wow you really switched a lot around on that chassis, looks like you moved the RX box to the other side and up front? and cut the brake servo mounts out? i was thinking of doing the same, however i was possibly wanting to use a brake servo for brakes, just because the brakes are really abrupt through the mamba.
again nice conversion.

BTW, i'm not a revo freak anymore. :P i was when i started but i dont like them anymore. however that is also a nice conversion.
thanks,
Aaron
