James, for club racing....you are fine to just give the motor a quick cleaning....clean the brushes with a comm stick....then clean the comm real quick....you should be fine....might be wise to give a cut on the comm before the main...
At a big race though, I would cut the comm every run and replace the brushes as needed....
The website is up.....batteries are in tomorrow and will be shipping on tuesday like mad....over 100 packs have already been sold!
CCristo, KR arms are coming....probably next two weeks....the machinist is working on the trinity arms now....KR arms will go down to him next....
Later EddieO
