I have installed brush cups in a couple of my chassis and got no improvement. It seems if you were running on a road race track they might help some as they would dissipate the heat better than the plastic and stop the chassis from melting. They would keep the brush springs form being sucked out from under the brushes, which has been a frequent problem lately. At least here in the SC shop. I have also tried brush cups and they did not make any noticable improvment in 15' 7". I agree with Dave in that they probably do work better in a road race. |

quite correct on the brush cups.
the Aurora Super II was based on a customized AFX chassis that was beating the TYCOs pretty handily in organized racing.
those certainly were road courses and the like, I am not aware of any organized drag racing at that time.
not all the improvements could be "TRANSLATED" to a production chassis, so they used what they could.
the young man, still under 18, was hired by Aurora to help design and work out the bugs of the Super II.
understand .... in that chassis the gold plated "spring", which would normally support the brush, was tack welded to the brush cup to help insure a more solid state electrical connection.
they may have been in the process of developing the Magnatraction AFX, but I don't think so.
the idea of a spring under the brush was however being used in the slotless Xlerators chassis.
so the spring in the brush cup that supported the brush was an innovation the young man brought to the project.
so yes, the brush cup was intended for duration and heat reduction to the comm and chassis, a heat sink so to speak, but also an integral portion of transferring electrical energy more efficiently.
can anyone tell us the name of this young man who would go on to help bring many more features in to modern style 1/64 slot car chassis?
?
PS, I have brush cups available. LOL

Mr Porcelli?
So many that have brought performance with innovation, be it a redesign of one part or a complete new thought. This is a hard one.
John Cukus comes to mind also. I don't think Robert Lincoln worked for anyone in the big three, independent innovator. Yes, my answer is Mr Tony Porcelli.

PS, I have brush cups available. LOL I have no idea on the answer, but I love the history lesson Al! The reason I tried them was for better conductivity. It was in one of my unlimited 4g and as I stated....they did not help. Also be prepared to sacrifice a chassis, because if they do not work the chassis is ruined. |

I just ordered 3 new AFX specialty chassis and top plates from Jag Hobbies today. Going for two completely new 4g Comp builds and 1 completely new AFX MT chassis Comp build for the Hot August Nationals. My Gassers should be OK I hope.

I am planning to run a completely new 4 gear car for this race. I hope that it runs well as it is difficult to get it slammed with clearance for the rear wheels.  |

Started doing some work on the cars for the upcoming race in August. Christine was out on the track creating havoc as usual but turning in some
good times also. Only ran over 3 plastic pedestrians, a new low, must have been in a good mood.

Looks like the front bumper has been worn out by running over plastic pedestrians, needs a repaint.
