540 Silvercan Motor Tuning - Johnson and Mabuchi
Our fastest driver, Yuichiro Takaya, recently conducted a seminar about tuning 540 silvercan motors. With his tuned Johnsons doing 21,000rpm legally without magnet zapping, we were all eager to pick up some tips.

He started by handing out a piece of paper with his notes. What the ??? hahaha. He then proceeded to talk for 30 minutes which helped decipher the notes.

Here are the key points that is per my understanding. I hope I understood correctly.
Basically the motor will give most power when brush contact is full yet there is still an "arc" or "curve" when viewing the motor brush. Then the power drops of when the brush becomes too short, maybe because spring tension is too light by then.
This was only his first seminar. There is more to come. Stay tuned!
