im looking at getting back into the sport and i am just going to use a 13 year old car, id say that its more about the driving style than what car you have.
get a half decent power plant and learn how to drive it then race... you will win more race and be higher up the table, having a half decent motor and being able to drive it to the max (consistant driving). Rather than having a beast of a motor and not being able to tame it and use 100% power.
id say that the ftx 's and mad rats for £89 RTR would be a fine starting point with a slight motor upgrade.
£89 or less for a RTR mad max or ftx or one of the lPR cars (slightly more £119 but come with better electrics and motor)
Maybe a motor i still run mod brushed £6 - £35
wouldnt bother with springs
lipos ace gens ar brill from giant cod and the C ratings have been tested and actually perform better than advertised! £17 for a 4000mah 25C
my two cents..... oh plus if you do have an underdog car and start winning due to consistant driving it also looks better
