[quote quote=17137]1.5mm ID Pinions are available but can be tricky to find.[/quote]
A little tricky but hot nearly as tricky to get as some of the tires we have been required to run 🙂
Noted about inserts. I will check the Tourist Trophy rules and see how Russ put it.
I have talked to Steve at Slot Car Corner. Is interested in a sponsorship. and supplying 10 (17.5k to 18k) motors. We will need to decide how to divide that 10 among:
Slimline
S-Can
Long Can
Here is a second draft of rules after some input, and edited to be more concise. There is an asterisk after some contentious items.
Monte Carly Rally Revival
Rules second draftTo be held on ASCC Rally track
One of the aims of this series is to see a variety of cars and approaches.Cars eligible:
Any car that ran the Monte between 1961, and 1971 Entrants should have some info and documentation on this. Cars should be a reasonable 1/32 depiction of the prototype.Multiple entries are permitted, but each entry will require a unique driver persona for the scoring software.
Model configuration:
Any hard plastic injection molded or resin cast 1/32model. (No vacuum formed shells) RTR slot cars /shells are allowed, but must run spec motor, and are not eligible for Concours. Cars must have interior tray (Vac form permitted) and figures for driver (with steering wheel) and navigator. Fantasy liveries allowed, but must be true to the period.Chassis/Drive configuration
Chassis: Any plastic or printed chassis. May be stiffened/reinforced.
Motor: any unmodified PREDATOR motor rated at or below 18k rpm
Guide/braid/motor leads: open
Gearing: open
Axles, front/rear: open
Ballast permitted, no weight limit imposed.
Ground clearance: Must not damage track, copper tape or timing system.Wheels/Tires:
Wheels to be a good faith effort to depict wheels on prototype vehicles. Wheels/tires must* not protrude beyond wheel arches as viewed from above. (If prototype car had wheels protruding beyond arches, documentation must be provided to scrutineer, and must be to scale) Wheel inserts are required. Maximum tire with front and rear (at bulge) 8mm•. Tire diameter should be scale to prototype within 10% after truing. Rubber or urethane tires allowed. Coating of front tires with nail varnish or C/A, etc. is allowed.
SILICONE TIRES PROHIBITED.Scoring
A series of 6* stages will be held on the ASCC rally track.
Each stage will carry X points per finishing place
An Index of Performance (under review) will be applied after applicable info is gathered, and will carry X points per (adjusted) finishing placeBoth posts totals will carry forward toward final score*
Concours to be judged by third party if possible. Points will apply to final score.
I can see no reason why front axle treatment should not be wide open.
A good opportunity to see what works.For me, personally, spec events are much more difficult, as there is so little wiggle room.
I’m a pretty poor driver, so I look for other opportunities to perform.
On tires: Every fiber of my being wants to keep the width to 8mm max, to keep this a scale series, but I don’t want to chase people away.

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!
Another eligible car will soon be available from George Turner Models.
Sumbeam Alpine resin kit

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;
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 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.
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.
