Randy – that is one very good looking car.  It will be interesting to see how quick those Elva’s are.

Posted for John-Lotus Jr.

Just received the red Elva today.  The Elva has a noticeably lower frontal area and cockpit.  McLaren has more rear spoiler.   Rear track: Elva (stock tires, full width) 2.425 inches, McLaren (slicks) 2.5 inches.   Slight nod to the McLaren there.  Wheelbase looks the same at 2.87 inches.  Elva gets style points for the Chevrolet valve covers (very cool!) If anyone has a red Elva already and intends to race it, I will change the number.  The McLaren is my weapon of choice unless the Elva proves otherwise.

Randy – Unfortunately you will not be able to run a 3D chassis with the March body.  Having said that, I do like your idea.  You will have to stick to a Slot.it Group C car for the series.

The Netflix piece on Randy Lanier was crazy.  It was almost comical.  His slide into drug smuggling appeared much less deliberate than Bill and Don Whittington.

Walt – I also wanted to mention that in addition to our tried and true road track we added another track – a smaller one lane, two loop rally track that is great fun to run.  We will be running two different series on this track in 2022.

Walt,

Great to hear from you.

I know there are many clubs that move around from track to track at members’ houses.  It’s more challenging here because so few people have a basement and running on a track in a garage in the summer heat presents its own challenges and having a spare room big enough for a track and multiple people can prove challenging.  Having said that, we are totally open to new experiences and are not opposed to running on a different track.  It would be great if you could come and present your idea to the group.  I can assure you the group would be open to hearing your idea.

We are done running for the year and will start back up on the 8th of January.  That would be the first opportunity to introduce the idea to the group.  It’s also the first race of the 2022 season – Slot.it Group C.  You should come and run with us.  We have spare cars and controllers so don’t worry if you don’t have something to run.

Looking forward to meeting you.

Marty

Randy,

I can’t wait to see your cars.  The Mustang sounds very cool in the Ecurie livery.

I still think the 914 will be the quickest but I like the mix of other cars.

Track Power:    12.0 volts

If it is not mentioned it is not legal.  These rules were written to create a fair event and not for racers to look for loopholes.

 

[porsche917]

Randy – The final decision on the track power has not been made but it’s safe to say that I want to have as many people compete as possible.  This in and of itself means the power setting has to work for everyone.

Any of the newer Slot.it cars are not any better than the cars we have been running.  The only thing you might find different is a lighter interior or one that has less interference with the chassis.  Other than that, the cars currently available are no quicker than what we have been running.

I would love to help you get your car and controller set up for the increased voltage.  I would suggest changes to the crown gear before you mess with the pinion.  A one tooth change to a crown gear has a significantly smaller impact to the gear ratio than a one tooth change to a pinion.

It should not be that much harder to run than it is currently.

[porsche917]

I found some front lights at Pendleslot made by PCS as well as TeamSlot.  The pictures show the TeamSlot version where the lights are in a bonnet/grill mounted version and the PCS loose mounted versions are available in pairs.

The History of Slot.it Group C Speed

It was twelve years ago that the Austin Slot Car Club ran its first series – the first Slot.it Group C series.  It’s not hard to understand why the club would choose these cars to run for its first-ever series – the cars were stunningly beautiful, easy to set up, loads of available Slot.it performance parts, and the cars were inexpensive.  When set up well these cars were fun to drive and were very evenly matched making the races very exciting to watch and run.

In the twelve years since we first ran the Slot.it Group C race series there have been improvements to the cars from Slot.it – adjustable front axles, stiffer chassis, lighter drive cockpits, and a quicker 23K motor.  All of these changes have increased the performance of the cars and made them more enjoyable to run.

 

Throughout all of the changes made by Slot.it the club has continued to run the series at the same 11 volts it did at the first race twelve years ago.  Running at 11 volts has worked well but almost all of the current racers are running the lowest possible gear with a 9 tooth pinion and a 23 tooth crown gear.  With almost everyone running the same 9×23 gearing the series becomes more about motor strength than car set-up and driving skills.  It’s true that driving skills play a big role in any race but even the best driver cannot overcome a down on power motor.  The differences in motor power are especially noticeable on a track like ours where the straight is such a large part of the circuit.

In light of this, the Slot.it Group C series starting January 2022 will be run at a higher track voltage.  The final voltage has not yet been decided but current thinking has it somewhere between 12 and 13 volts.  The 12-volt setting did not seem to be too big of a change and 13 volts seemed like it could be too much.  There will be lots of testing taking place in November so that by December the final voltage number will be announced.

How does the change in voltage affect how my car is set up?

·         You will have to reevaluate the gearing you are running.  If you are currently running a 9×23 gear you might have to move the crown gear up to a 24 or 25.

·         You can add more weight to your car without the same performance penalty you would have had at 11 volts.

·         You will need to glue your rear tires to the wheels.  If you have been able to get by without gluing your rear tires to the wheel you will have to now.

·         If you choose to run the same 9×23 gearing you will more than likely not be able to run at full throttle on the back straight.  The higher voltage with 9×23 gearing will require better throttle control.

·         You will need to adjust both the sensitivity and brakes on your DiFalco controller.

[porsche917]

Mark,

Thanks for sharing your story.  Its good to hear about other forms of slot car racing.

[porsche917]

WOW!  That is a whole other level.  I like what you are working on.  I think you and Russell are the masters at that type of work.  I am always impressed with the quality of work you both create.  Impressive.

[porsche917]

Mark, Randy, and Russell – Thanks so much for getting together with Bob.  It sounds like a fun time was had by all.  Glad he came back to visit us.  Hope to be able to make it the next time he comes around.
