Were you at either the 2003 or 2004 Mini-Z-Cups Nats?

If you've raced Mini-Zs for almost 2 years, that was prior to RCP Tracks and prior to the MR-02, MMT, and newer PCB F1s. It's also prior to FM MR-01s radios and PCBs. Mini-Zs handle very well or as well as the driver can handle them on an RCP Track. Perhaps, not on ozite without foam tires or outside on pavement. Kyosho also has a limited warranty on the PCB and even if a motor fries, one is cheap enough or you can always add FETS and a rebuildable motor.
