which micro??
 

i want to race a micro but dont know which one to go for or which is the best setup ? any advice at all ? cheers

also could i use my core rc 5008 servo

in my opinion if your only going to race indoors i'd go for the carisma gtb as its a very popular car at the moment but if you want to race outdoors on say dirt and gravel i'd go for the losi mini 8ight or the emb-1 as the diffs are in a sealed casing and cant get stones or dirt inside them, unlike the gtb,

lots of info and advice here about the Micro class. :)
