If I have extra cash for nothing, here are my Fastest Setup Dream :
Lipo 8000HV 4S2P 14.8V Pack
HV4.5 High-Voltage Brushless Motor
HV HIGH-VOLTAGE BRUSHLESS ESC
Three Capacitors in parallel mode from Novak Electronics HV/Super Duty Power Cap Harness: 2700µF
And my Tamiya 415MSX, with stupid FDR and foam tires.
