get some 3000 epic batteries from tower for 18.00..i have 2 packs and it last me about at least 2 hours of drifting.. and with the brushless set up youll get more run time than a brushed system..and to me a brushless seems the best way to go even if you have to wait forever to save up for it..cause in the end youll be happier cause you saved money and get better performance and no maintence. but really i didnt have that much patiences and i juss bought some cheap electronics cause i wanted to ride already.

about the kit..did you find it hard to put the pin in the spindle part where the wheel hexes go..
