Actually to prove my point there is a local guy who was racing yesterday and he has the xfactory carbon chassis and he just couldn't get his b5m to work (track was a lil loose) so he said hes going to put it back stock.

I think the key to stock is a good motor (not a $200 motor but like a killshot with a HT rotor which is what I run), battery and maybe do some things to lighten the drive train like pucks and aluminum top shaft. Thats it.
