hi doobe, just finished mine w/alot of help from this forum.Mine has been a bit of a hard case as it's 5lbs6oz rcm conversion w/truck tires so i ended up w/MM and medusa36-60 on 2&3 S.Out here in the OC the St folks are running MM/5700,the veleneon KV?,and Many are running the GTBw/6.5 and all seem to be having realiable success for racing good luck and by all means have fun first
