Honestly unless you want to do high speed runs,where is 47 not fast enough in an Erevo?I'm not sure what you do with yours,whatever you drive, but with mine I do stuff like this http://s531.photobucket.com/albums/d...t=100_0619.flv Now I did enjoy my Medusa on 6s and running about 60,for the 5 minutes the Quark would handle it :) and thats about all I felt was neccasary,since it led to reglueing my tires.As it is the Novak blows the tires off every few runs,so thats enough for me.
