I appreciate your input and agree with your points to a degree. I too never ran wing cars in the 70’s but did run AFX G-Plus cars in the 80’s and they did run foam in their stock configuration. Having said that, I am not married to foam but the big cars work so much better using them, or at least they did at one time. We need to figure out what we need to do to get the tires to get some grip. I will be at the track next Saturday working the problem. Any and all help would be welcome.
RevoSlot – the tires for RevoSlot were hard to come by and were very inconsistent. The idea was to move to a foam tire that would be far more consistent, easy to source and equally if not more drive-able. The other thing is the Scaleauto foam tire is the same width for everyone where the RevoSlot Porsche uses an 8mm rear tire compared to the Marcos 9mm and the Viper/Toyota 10mm. Now all the cars will run the same 10mm width foam tires.
Realistic Speeds – I don’t think the BRM Group C cars speed will be out of scale, in fact, I believe it will be closer to scale than the other series we run.
The Wear Lines on the Track – The wear lines on the track can be removed after we run the series or we can stick with foam tires moving forward. A question the club will have to answer.
The trouble with wheels/tires……….
In spending a couple of hours running the BRM Group C cars today with the goal of “rubbering in” the track I found there was little if any improvement to the cars grip. I called Alan at 132slotcar to get his input and learned that the BRM wheels/tires I have spec’ed in the rules are a hard compound of foam and will only hook up once the track has many many hours of running. The Scaleauto ProComp 3 tires we used to run are softer and would hook up better but Scaleauto no longer makes the replacement BRM wheels. In looking for a suitable option tonight I discovered Scaleauto produces a wheel/tire that is .5mm wider (16mm vs 15.5mm) and 1mm smaller diameter (27.5mm vs. 28.5mm). Unbelievably, I had mis-ordered a set of these wheels months ago and have them in hand to see just how they will work on the car. I mounted them to a Porsche, Mercedes and a Toyota and they fit perfect on all three. The lower profile also allows the car to sit lower in the rear and that can do nothing other than improve the cornering. I will be taking the cars to the track on Sunday to see how they work. I will update the forum and change the rules if needed.
Randy – The rules were updated a couple of days ago to include the verbiage of having the weights inside the car and not visible.
The motors all have different RPM and Torque ratings to I am going to leave those open choice. The black motor that is in all the newer models will work fine so I wouldn’t worry about changing it.
Randy – you can check a local machine shop and see if they have any surfaced metal plate available for sale. You can usually pick some up for $20-$40.
When I posted the question asking if we were going to publish practice times it was done with the goal of making the series and practice times fair for everyone. To find out practices have already been held or that we will “open the lid” tomorrow without any advance notice is bullshit.
The idea in locking the top was to keep it from being opened by any one individual to practice when others could not. Our regular track is open all the time but the rally track is not and should not be opened without it being posted in advance and available to all.
This was discussed and agreed to by the club members in previous meetings. I have not heard any discussion of that being changed for this series.
When are we allowing practice for this series? I feel like that is a key piece to being competitive. It would be great if we could agree on dates and times early enough for people to adjust their schedules accordingly. Let me know what everyone is thinking.
Very nice work. I love the Sci-Fi angle. Are the pods from a Twilight Zone episode? Thanks for sharing your track/creation.
Mark – At this point I am inclined to say only the BRM wheels will be allowed. This will take away any possible difference between wheels you can get and wheels you can’t get. Update to follow.
Mark – These are virtually the same wheels. The catch is – there are no Scaleauto wheels available anywhere around the world that I looked where the BRM wheels are available from multiple retailers here in the States.

Here are some updated pictures from today’s limited amount of work. This track looks like it will be super fun and fast even though its on the small side.
The new Scaleauto RevoSlot wheels/tires have arrived. I will be testing them over the next few weeks to see how they perform and will update everyone on this forum. Can’t wait to try them.
Mark – Before I update the rules with the new wheel/tire selection I want to confirm that they will work as I hope they will. Once I have some laps with them I will update the rules with the exact wheel/tire spec.
The only bearings that are allowed are the stock closed bearings.
Lubricants? Use what you have. No need for rules regarding lubricants at this time.
