hi guys. i've been thinking about getting a Tekno RC V3 Brushless Kit for my losi 8b as i'm getting fed up with nitro and like the idea of running a brushless 8b as my boy has a few leccy cars and they just seem so much easier plus we can use them outside my house unlike my nitro's and petrol rc's.now i'm new to brushless set up's and lipo's so what i really need to know before i buy the tekno kit is what kind of brushless + lipo set up would i need ? and is the tekno kit worth getting or is there a better one out there.i race my losi 8b so i would need it to be just as fast as my nitro and get at least 20 min run times out of it.so any info and links would be a great help as i really ain't got a clue
