F-Brush
EA-the new formulation of the F-brush might be the real deal. The EA ROAR stocker I bought with them in I ran 4x and after 4-runs-the comm looked almost as good it did out of the package and there was more serrations left on the brush then I've ever seen after 4 runs. Motor ran stout too.
I am going to order a ton more and start doing some motor testing.
Thanks,
Ray
