Waxahachie Regional BRM and ScaleAuto Race

I would be interested in running the Scaleauto race

I plan to attend as a marshall/observer. I have a BRM 962, with AW upgrade kit that can be borrowed to race. I have spare crowns, motor and tires.

If you have the car and are going why would you not join the race. It will be a blast Racing on a 155'blue king track with big cars with 20 people

All,

For anyone on the fence about getting a ScaleAuto car and wondering if it will work on our track - they will! ScaleAuto released a new soft compound tire that works great on our track. If you are purchasing one of these cars I would recommend getting these tires as well. They will allow you to use the ScaleAuto on our track so you can get a better understanding of how they work, how to set them up and how they drive. Let me know if you have any additional questions.

Is any 1/24 Scale Auto car eligible? I am thinking about getting a BMW. M3 or Z4? What Z4 do you have?

Yes, any scalAuto car is eligible. There are only two Z4's with the latest R4 chassis. The VDS and the Japaneese car. I have the VDS but will be painting a body to relocate the 2012 24 hours of Nurburgring car. Decals on the way from Pattos.

I'm starting to think this is more trouble than its worth. By the VDS Z4 do you mean #SC-7059? And what's the Japanese car? The Scale Auto website does not list any R4 chassis on Z4s. The #SC-7059 is listed with a SC-8000 R2 chassis. 132SlotCar.us doesn't say crap about the chassis, although they do list numbers for chassis parts.

I found Pendle does a good job of letting you know which chassis the car has that may help you make a choice

I for one am going with the Mid-Ohio Viper solely for the Forza logo

Will they allow fantasy liveries?

Yes, fantasy liveries are welcome.

I ordered the DHL BMW Z4 but I will be going with a different livery.

Russell,

The Scale Auto website is a good source or information as well as Pendle Slot.
https://www.scaleauto-slot.com/catalog-2014

The chassis you want is the SC-8000 R4. The R2 is OK but if you are spending the money you might as well get the latest version - the R4. It only comes on a select number of the ScaleAuto cars. Basically the latest releases.

The car I purchased is the Marc VDS Racing Team #SC-7059. I am using this car as a mule. I will be painting a car to match the team BMW Z4 from the 2014 Nurburgring 24 hours.

First Time out with the Race Prepared BMW Z4

Just like a real test day I am here at Kings at 10:20pm on Saturday night running my “blue printed” ScaleAuto BMW Z4 for the first time. Here is what I have learned.

1. Every bolt, and I mean every bolt needs to be secured with blue Loctite. I didn’t put it on the rear axle supports and they came lose after the first 20 laps.
NOTE: The Philips head screws have an interesting head on them that does not mesh with all Philips head screwdrivers so make sure you have a good fit before you force a bad situation and round out one of these screws.

2. When you think you have the screws tight, you don’t. I thought I had the motor mounting clamps and bolts tight but 153 laps later the screws loosened and the motor/pinion backed off of the motor and left the car at a standstill.

3. Be careful in truing the ScaleAuto soft rear tires #SC-4736. These tires worked great when I put them on the car. They weren’t true but I thought that could only make them better. Once again I was wrong. They are like truing very large shore 15 tires. You have to be very careful with them or they will melt/gum up. I was able to true a good pair of them and was looking forward to running them tonight. I was surprised when they did not have the same amount of traction they did before they were true. I was also surprised to see the rate at which they were shedding rubber. They ran like shore 15 tires with large balls of tire rubber building up on them when pushed hard. The tires could run for eight to ten laps before I would have to stop to remove the balled up rubber from the tires.

My best lap time of the evening was 4.529. Time to go home and spend some more time getting the BMW dialed in. Good luck to the rest of you working on your cars.

Marty,

We need to figure out rules ASAP. Alan is in Europe and I don't see the national rules being update anytime soon.
As far as tires go, we should get whichever foam tires are being used in Waxahachie; do we know that?

Regarding the currently published rules (https://slotcarillustrated.com/portal/forums/showthread.php?p=899357):
Let's start the wrongs list:
- Stock gearing: (fundamentally wrong - must on our club will understand why as it has been discussed over and over (there aren't 2 motors alike, nevermind 20).
- Shoe goo only: those of us who raced at the BRM 24hrs know how well that rule worked - epoxy should be allowed.

The good list: I did see that we can use lock nuts and use any size t-nuts to adjust body movement.

We have been running these cars in Tyler for a couple of years. We have had good luck with them. I would recommend replacing the nylon pinion with a brass or steel pinion. You can super glue the nylon pinions, but they always cause problems eventually.

Scaleauto basic set up tips. This was taken from the Scaleauto Facebook page and translated as best as possible. There is some great basic set up information here along with some great pics to show you what they are talking about. Enjoy.

The final rules for the upcoming Scaleauto race in Waxahachie are attached. Everyone can start to preapare their cars to these rules. Let me know if any of you have any questions.

Marty

I will be at the track tomorrow, Saturday April 4th, to work on my BRM and Scaleauto cars for the Waxahachie race. I will have all my BRM and Scaleauto parts with me if any of you want to come up and try some thing out.

Marty

under ground Clearance

• The front of the car cannot be held up by the braid when checking this measurement.

WTF does this mean. I have been reading through the rules and this one I don't understand.

also how else would they be attached

• Soldering is only means by which to attach lead wires to the motor terminals.

are we running at 12v?

Steve,

The braid from the guide is not permitted to push the front of the car up to give it the 1mm required ground clearance. The surface plate used to measure the 1mm has a large hole in it where the guide would go so it does not affect the measurement of the ground clearance at the front of the car.

We are running at 12 volts.

Great questions.

Marty,

Regarding the nylon lock-nuts: In order to use the nylon lock-nuts, in some cases, a longer screw is required. There is no mention in regards to what type of screws can be used, etc. Can screws be exchanged for longer/shorter versions? Scaleuato only or is that an open choice?

Ary.

Great question. Screws can be changed out for any Scaleauto screw. Scaleauto offers many different lengths of screws for almost every part of the car.

Marty

The official wheel/tires we will be using are: Scaleauto ProComp 3 foam 13mm wide/27.5mm outside diameter. Part # SC-2421p.

You have officially been notified.

Marty

Marty,

Do we know the controller interface of that track? (XLR, alligator)

The controller interface is alligator clips.

BRM and Scaleauto tuning day is set for April 25th at 1pm. If you are planning on attending the BRM-Scaleauto races in Waxahachie please plan on attending this tuning session so we can share notes and help each other get our cars ready for the race. I will have spare parts for both BRM and Scaleauto cars. If you are running a BRM I would suggest you order an anglewinder chassis conversion kit. You will need to make sure the chassis is absolutely flat and be prepared to bake it if it is not.

I look forward to seeing everyone on the 25th.

Will we have another tuning and practice day in the coming weeks? I think Sundays would probably be best, or after our regular Sat races.

What is the plan for building/tuning cars for the people going who dont have their cars (or cannot afford one).

What is our strategy regarding the BRM -vs- Scaleautos.
-- Who is racing BRM only, ...Scaleauto only .....Who is racing both (verify data on our forum)
-- Who has a car; who needs to borrow a car?
-- Who needs tires, gears, etc. Can they buy from Marty or should buy from Alan/132slots.
-- Schedule a BRM practice; ... a SA practice (on the same day I assume, but can we designate specific times or order?)
-- Weight and body float tuning -- need some guidance
-- Sponge Tire truing -- need some guidance
-- BRM front tires - should we true them to get them to minimum diameter, or just let the track do the work?
-- Local tech inspection. Confirm that everyone meets the specs before the trip?

SCALEAUTO GEAR LASH ADJUSTMENT
Is the recommended method to adjust the lash by moving the motor in/out with the motor mount screws?

Also, other than replacing any spurs that are not oval or tacoed, are there any other best practices?

GUIDE DEPTH GUAGE
...aka....surface plate used to measure the 1mm ....

Marty do you have one of these? How safe will it be just to eye-ball the guide and use a micrometer/caliper?

Will we have another tuning and practice day in the coming weeks? I think Sundays would probably be best, or after our regular Sat races.
[b]Topic for Saturday’s club meeting[/b]
I just got my ScaleAuto white kit, and sponges for both cars. I'd like to put on sponges and practice, but dont want to mess up the tracks traction. (or I can live with rubber and just practice with sponges on Sunday morning at AllScale).
[b]Don’t wait to get to All Scale Raceway to practice. The sooner you begin the sooner you will get an understanding on how the cars handle. You will also need to drive on the track to tune your car as best as possible for the race. [/b]

I also think we need to get some cars together for the people going who dont have their cars (or cannot afford one).

I think we also need to have a strategy regarding the BRM -vs- Scaleautos.
[b]What do you mean “strategy”?[/b]

[b]I have everything anyone would need to get their car set up. People can use my parts for a tuning session and for the race when we are in Waxahachie.[/b]
-- Schedule a BRM practice; ... a SA practice (on the same day I assume, but can we designate specific times or order?)
[b]This is more up to what everyone’s schedule will allow. We can discuss this and many of your other points at Saturday’s club meeting[/b]
-- Weight and body float tuning -- need some guidance
[b]Other than saying you want to have body float using weight and where to put it is up to the individual based on their car and their driving style.[/b]
-- Sponge Tire truing -- need some guidance
[b]No different than rubber except it takes much less time and effort. Be sure not to true them so much that they do not meet the rules.[/b]
-- BRM front tires - should we true them to get them to minimum diameter, or just let the track do the work?
[b]True them but don’t true them down to the minimum because they will wear during the race.[/b]
-- Local tech inspection. Does everyone meet the specs before the trip?
[b]The rules are posted. Anyone building a car that is not meet the specs should have their head examined. If anyone has any questions they can ask either Ary or me to check their car and make sure its legal.[/b]
