Fuzzy I read the same thing, and I have a hard time believing that. Eric has been running TC and mod oval in preparation for Snowbirds so he hasn't had time to do his own 12th scale motor tuning. I can't speak for Mo or the other guys up north but I bet they are working on tuning the brushes for 12th scale. I'm guessing your best bet right now for that info is Mo Denton. I would like to add that I have a VERY hard time believing the EA Motorsports F brush is poor in lower voltage racing. The key is that nobody has found or posted the tune for that situation. I'm going to step out on a limb here and say that a good brush is a good brush, it just needs a really good motor man to find find the sweet spot.
