Cheers Neil. I was told it was a 3 pole, what difference will that make exactly? I don't intend to mix capacities I have been running the car on 2s, and although not lighting fast, its still pretty nippy and seeing as I am a begginer still really, it is better for me to have something slower rather than blazing fast and smashing the thing up Can't wait to get my mits on some 4s packs though, should be awesome fun!
