Hi 
Has this improved the lap times on your cars .. motors ?

Lap times have decreased by a few seconds, there is a definite audible improvements and to the feel under thumb and finger rotation.

I am trying to find a motor RPM tester, the ones that suggest are for RC cars or planes etc that require more stuffing around such as painting white lines on wheels/tyres. If you know of an RPM tester fo9r Slot cars and have a link that would be appreciated. 

I'd say regardless just removing all that garbage out of the motor would have to add to some performance

Now, THAT is the question. 
I always do an rpm test , pre and post dip to be sure that I get a proven performance uplift.
