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. https://www.youtube.com/watch?v=IXikEiQdUzY
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.
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.

-Warren ZevonIn 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.

-Warren ZevonIndex 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 tiresDivide Triumph width by Porsche width for INDEX Factor.
Index factor in this case is .71942Both 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.

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;

Sammy with MontroseGrrr…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…

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

Know anyone with an Elegoo Saturn? My printer is not quite big enough for 1/32 bodies, unless I print them almost vertical, which can lead to problems.
for 10 Euro, I’m considering giving it a try. Gotta have a Saab!

-Warren ZevonI think a metal chassis would potentially have a big advantage in keeping the weight of the car as low as possible and give the car an advantage with added stability. I might be missing something here about the availability and ease of use of a metal chassis but I would be concerned there would only be a few members that would want to put the work into finding the right one and learning how to set it up.
I am worried about making the rules too difficult for members to participate. It’s already challenging for some members to prepare a spec car much less a builders car. I think it would add another layer of difficulty that might push members away from running the series. One of the key factors to consider in running any series is the level of participation. If only half the club participates then it’s not a great series to run. The easier we can make things for members the better it will be for the club as a whole.
