P2K Brush Question
 

I got a couple Copperheads for stock racing and they need brushes. Anyone know what I should use? I'll be running offroad buggy and mod 2wd with GTXs and Lipos. I really need to know if I need laydown or upright brushes, but a recommendation model-wise would be welcome as well. Thanks in advance.

P2K's are laydown brushes. Use some Reedy 768's if you can get them, or 767X if not.
Also to get a few more rev's use some polarised springs. Trinity purple and red's with the harder brush on the +ve side ;)
