I live in Rayleigh and want to race every now and again. Lawford/ Coastal in Ipswich look cool but are a bit of a drive. Is eastrax closer, what format, what tyres motors etc are you running. So far i have only got one 4500 mah pack- orion rocket.... I need to get another stick pack...will it need to be 4500 or can i save a few pennies?
