Lots of activity in here!
So, let's start at the begining... it looks like you guys have hit on the 1/12 gearing answers yourselves! Cookie's rollouts look acceptable to me. Always monitor the ESC and motor temps!!
Chicago: I will not be attending... someone has to stay home at the fort and keep everything running smoothly! Charlie, Bob, and a bunch of other very friendly and knowledgable people will be there though!
Now, to address the question about brushless/brushed equivalency:
We have striven for a long time to try to make "equivalent" motors for stock and spec racing and I think there are alot of factors that go into this whole debate. As technology changes and our knowledge of it grows what was once considered "equal" can now rather easily outpace what came before.
Obviously the 10.5 and 13.5 classes are pretty popular ... in some areas everyone has migrated to brushless... in others you have situations like you have described where everyone is split... instead of having a large group of racers you now have many small groups of racers.
We (and other manufactures) are currently working with ROAR to try to hammer out some rules/changes that will the best compromise that we can do.
There are many sides of this debate and to go into all of the factors would take far too long than I have in my spare time here at work
But, the simple answer is "Yes," we are working on making it so that the gap between brushed stock/19T and brushless stock/19T is smaller. I really don't see that going back to bonded rotors or limited gear ratios are really feasable for a solution...it would also require alot more scrutineering and that seems to be something that most tracks or people really don't want to do.
It sounds to me like there might be some agreeance on a slower wind motor such as a 15.5 or 17.5 motor with sintered rotor. While this might upset people who already have 13.5s or other motors I would recommend that you compare the cost and life span of a new brushless motor with that of the cost of the brushed motorS, brushes, and equipment you would have needed to get the same performance for the same amount of time with brushed stuff.
