I have been racing 1/12TH even longer than Jason, and I have to agree with his comments. The cars in that video may, and I say only MAY, have been faster for the first minute but that is all. Did you see them struggling to finish? At the very worst, after the 4 minute mark a 17.5 boosted car would start to eat them up, badly. A modern 1S mod can dump a 6000+ pack in 8 minutes. That is very serious power and would cream those cars. 17.5 blinky is bringing racers into the class because it is slow enough to be driveable. If you want to go faster, pop a 3.5 in there and let her rip.
