it think the big thing about brushless is whether it will stick around or not. the first week of truck the crowd was huge and now its down to about 12-15 drivers. i cant wait to run brushless and i hope it sticks around.
I said the same thing 2 years ago but I see in some TC races brushed motors are still beating brushless set-ups. And with two classes still with brushes it should be fine. You may see more guys run 2 classes with brushless offered.
