Proposed 2022 Race Series - Monte Carlo Rally '61-'71 Proposed builder's series for rally track

Just thinking. Any practical reason not make brass chassis legal?

Another eligible car will soon be available from George Turner Models.

As much as I can see the overall width playing a role I think the width of the tires is a bigger concern.  My example:  I think I am going to run an MRRC Porsche 904GTS which is a very narrow car and is much narrower that the Fly 911 I was going to run.  Even with the narrow width of the Porsche 904GTS I can still mount 10mm wide tires front and rear using a 3D chassis and CB Design wheels.  I believe these wider wheels/tires on a narrow chassis will be the best of both worlds and be hard to beat.

We might want to take a look at the old Mille Miliga rules from 2012.  The rules stated that the widest tire you could use was 9mm with either a 22mm or 20mm diameter.  This alone could do a lot to level the performance.  NSR make a selection of 8mm width tires that we could look at using for this series.

The rules for the 2012 Mille Miliga were very simple.  I have them below for review.

Grrr...lots of Saab models at 1/43. Can't find a single one at 1/32 (except for a resin 96 by Oscar Models that is apparently not being sold anywhere).  A Sonett II would also be cool, but nothing but 1/43. The search continues...

CORVAIR - if we paint GM on the valve covers, can we use a Porsche flat-6?

Marty,
40 (herald width) is %71.942 of 55.6.(911 width)
Since width at rear wheels seemed to be the main attribute being pursued, I used relative width to arrive at a factor to apply to time. I thought it would be a good way to get people to entertain cars other than the lowest/widest to get a more varied field.

Endurance races, like Sebring, and LE Mans use fuel consumption as a factor in their Index of performance, but that really isn't applicable here. Still it did yield some interesting results at times;

I am curious how you came to the number 0.71942?  Not arguing it, just curious.

Index of performance:

Handicapping formula:

Measure width across back wheels of all entrants

Compare entrants’ width against widest (Benchmark) entry

arrive at index factor of entry X against widest entry by dividing entrant x with by benchmark.

That index factor is applied to entry X’s time.For example:
John’s 911 is 55.6mm across the back tires. Being the widest competitor this is the BENCHMARK dimension for this race (stage)
My Triumph Herald is 40mm across back tires

Divide Triumph width by Porsche width for INDEX Factor.
Index factor in this case is .71942

Both make 40 laps or rally track

911 completes 40 laps in 360 seconds

Herald completes 40 laps in 430 seconds

Handicap is 430 X ..71942

Handicapped time is 309.35 sec.

I think in the interest of a varied grid, the Index of performance will be weighted equally to overall performance points-wise So, conceivably one could winn overall, AND Index of performance for double points!

Can anyone point me towards the method used to score the Targa Florio rally earlier this year ?For the second time in my life I wish I knew how to use a spreadsheet.

In the interest of a varied grid I am looking into a few possibilities. Need to have at least one french car, right? So I found this SCX Renault. And going more scratchbuilt-ish a '61 corvair, if I can make a silk purse out of this sow's ear.

I would like to, as much as I can, encourage variety, and scratch building/kitbashing in this series. To that end, I think an Index of Performance trophy is in order (formula to be determined, but most likely based on overall width at axle factored against race times) and a meaningful number of points for the concours.

Entering as multiple team members seems like a fine idea, but should probably set a maximum number of cars one person can run.

I don't want tires to become a source of consternation and stress, so I am leaning toward tire/wheel choice being fairly open, as long as they adhere to the look of the prototype car racing in the day. This is a scale event, after all.

If I am able to contact the guys at Slot Car Corner, and can secure a bag full of Predator motors, we will go spec, but if not, will need another approach. 18k and under, perhaps.

Since I have never been a series manager before I ask for your guidance and patience in this.

-Marc (Datto)

I just saw a new Predator motor that would be the correct choice for my Mini.  I am open to the Predator sponsorship if possible, but would just as soon use what come with my SRC and Pioneer cars. 

I have a Mustang coming for the race that would use steel wheels like cars came with in the 1960's.  SCC has some that do not use inserts.  CBD0350 CB Design 1:32 Classic Steel 14 x 6mm Wheels (slotcarcorner.com)  There are some members who have wanted to use the spoked CB wheels and stock car race wheels.  I suggest allowing these non-insert wheels.

Here are entry lists for the Monte Carlo Rally from 1961 to 1971

1961

1962

1963

1964

1965

1966

1967

1968

1969

1970

1971

I think that the rules for the Monte Carlo series should be somewhat loose concerning wheel/tire width/track width.  There are a lot of unknowns with the rally track for car size, width and so on.  A small car with little wheels/tires may well outrun a larger car with wide tires.  Keeping things open for the first races will allow for experimentation to find out what works.  The balance between tire grip for the straights versus the cars sliding in the handbrake turns will be interesting.

I believe that I was the one who first bought one of the Group 2 BRM/TTX 1:24 “mini” cars for a possible series.  I propose that we defer these cars for consideration for series in the second half of the year.  I think that these cars would make an excellent series, I have not run any of them yet.  Considering the array of chassis setups, some with differentials, some with freewheeling fronts, and the variety of cars, we need more time with these cars to see which cars and which setups we want to include for a series.

Russell

I think the Monte Carlo tire width should be 6mm which conforms to the stock tires on most older cars and there are plenty of after market wheels with grub screws, inserts and tires.  The 1970's era cars with 3d chassis have room for 8mm tires, but they should run spacers to get to 6mm.  Otherwise run a separate class for 60's cars with narrow tires and early 70's with wide tires.

The cutest slot car I have ever owned, and maybe another iconic car will show up Saturday.  Both narrow tires even with the aftermarket wheels and tires.

Pendle's has "10 inch" aluminum wheels, and tires to go with. (I think they are rubber rather than Urethane)

Sounds like a good idea - you guys thinking the 12k or 18k Predator?

BTW - I have experimented with the Piranha brand 21.5k motors they sell, and find them to be Reliable, $8 (yes half a Slot.IT price) equal to the Orange-Bells.

OK with me for Predator if we get "slow car corner" to sponsor.  Have you decided to at least allow reference to IMMENSE F1 driver heads?

O think there is (or was an Ocar Saab 96 shell. Car shells need a lot of work, they tend to be thick and heavy, I hear.

The reason I was thinking spec Predator motor was among other things, approaching slow car corner about being a sponsor for the series.

Will have to re-thing ground clearance. Just measured my TR+6. (Did not run the Monte, but some Spitfire fastbacks did.) Anyway, with the small wheels, the motor can is less than 3/32 from the set-up block surface. Would like to avoid slammed cars that don't look right for the period.

Randy - I think the Scalextric Mini with a 3D chassis would be a great car for the rally track.  There is virtually no weight hanging over the back end.  The little wheelbase should work well on the rally track.  Can't wait to see it.

Porsche 904?  What the heck?  I had no idea the 904 had done the Monte.  That is crazy.

Alright, I did just order the most iconic Scalextric Mini, the Monte Carlo Rally red with extra lights and Monte Carlo sign age.  I wanted one for years, so even if it does not pan out I'll enjoy it.  I still would like some info on a scratch body one a 3D or Policar chassis.

Marty, you can run a BMW 2002tii sedan finally, if not a Porsche, or Alfa, or Alpine.....

P.S. I understand a CG Slots Maserati Birdcage will not be eligible, but the year I saw it live, 1960, the Camoradi paint job was not on it, so the #66 would just need a number change to #5.  Hmmm.

I have a fly 911 Rally with the navigator head bashed in and BFGoodrich Canada decals for Ludwig Heimrath IMSA.  Has the little duck tail.  I have the original narrow wheels and tires that would put it in rally track shape.  I also have the low end motor, but also the Olifer chassis to make it a big track car.  I strongly advise that the rules spec a tire and wheel combination that is narrower than our Targa Porsches.  The motor size also appeals to me, but allow any 12k motor like a Scalextric would have as a white end bell. I have wanted a small Austin Mini Cooper from Scalextric and would need narrow tires.  The 904 and 914 (I almost bought my neighbor's in 1973) are enticing.  I keep wishing the rally rules allowed multi-car teams because I want those cars.  For information use, are there some appropriate bodies for scratch building with a Penelope Pitlane or Policar F1 chassis, like an old Saab?

You are the man!  I love this idea and you have put the work into the rules on the front end.  Well done.

I think it would be either a 911 or 914 for me.
