Hpi Pro 4 Bl

[Thunderbruiser]

I just won a slightly upgraded pro 4 and i wanna run a bl sys. that will give both run time yet be pretty fast on 6 cells....I was thinking for the novak 4.5 but i know i could get a faster system then that so i was just wondering what's your opions on that....this car will be used for drift,track, and fun....so i don't want just pure speed!
