thanks for the reply, but when "at the track" for some testing on springs and brushes, how do you "monitor" what changes were "good or bad"????
so before placing the motor on the track, you have a "head start" on working on a combination/starting point that is suseptible to the track conditions and type of performance you are lookin for on that particular day....
