Need help with 4S racing setup

Is everyone running higher votage race setups?

1512 2.5d, 4ea. 2s 5000 neu energy lipos=$645 for lipos and motor that won't make it the full length of the A-main. It's frustrating the tecnology is not there yet.

I think I need a crt.5, xxx4, or mt2 to turn laps until there's better race buggy setups to buy. I love my brushless/lipo mf2 but the track is too dry and loose most of the time for two wheel drive.

Thank you for the advise gentlemen
