Actually, at some of the smaller tracks up north stock 4 cell 1/12th is getting too fast for novices wanting to get into it.

Thats not the main reasin for trying LiPo though. Its battery life. I race competatively. This means replacing batteries every 4 months or so even though I take obsessive care of them. After 4 months wether you race them or not, take care of them or not thier IR's go up, run time goes down, cells drop dead for no reason, etc....

I have 2 year old LiPo packs for my R/C planes and helis that are still as good as the day I got them.

I will be testing 1s2p (3.7v) 4000mah and 5000mah LiPo packs in 2 weeks at the next MINNREG race in practice to see for myself how the car handles. I plan on testing a Novak 10.5 and a Novak 4.5.
