Graham, my ask is that you consider adding the 69 Camaro, Porsche 934 back in please. I’ve I just received a ton of parts and even opened a Porsche that’s been sitting since April ‘2021 and started building cars, I assume others may have started doing the same. 

On the wheels, I assume you are measuring at the rib and not the face as I’ve seen this complicate building in the past.  I suggest a simple 15x6 to 15x10 minimum size rule.  Unless the vehicle was equipped with a smaller diameter wheel. 

Just a comment regarding B&W chassis, if there are 10 cars with B&W chassis maybe consider it as a class on its own without a body restriction as with mounts the bodies are as heavy as other bodies.

I have restored the Porsche 934 & Camaro 69 to the list for you 

In the past you could have said that the "Richard Mack chassis " were commercially available, but sadly Richard does not seem to sell them anymore.

Sorry but Not being very familiar with the Porsche 934, I checked it out this morning, and like the Porsche 911 RSR it has quite wide wheel arches compared to the other cars in this Category. So I think it is out of context of the other earlier cars in the " Monte Carlo -Sports car" category, and have moved it across to the "Tour de France - Touring Cars Category. It's now in the same list as the Camaro 69.

Fly Porsche RSR is 58mm at the rear.  Fly Porsche 935 is 62mm if the body is raised as the fender tappers down towards the edge.  Possibly 2 different classes?

As you know it is always difficult to generate a "slot car list" which is not biased towards certain models" and I had intended that the Class C & D cars would naturally split up into narrow Monte Carlo Sports Cars and wider TDF Touring like cars. But on reflection I don't think that worked well.
However today I also realised that the Porsche 934 could not enter the TDF Category D Category as the competition ended in 1974, so it is not listed as having been entered.
I believe the solution is to bring forward the Class F Monte Carlo Modern Rally cars to 1975 and narrow the time frame for Category C to 72.
 So effectively the Camaro 69 remains in Category D, and the Porsche 934 is now in Category F.

The idea is to enable the widest range of cars across the entire period, and place the Slot cars into Categories which have some historical reality, but also equally important to have the best "Slot Car Competitive groupings" so we don't get too many of the same or dominant models.
Not an easy task......

 Good afternoon,
I have been revisiting the proposal for next years Road Race and the latest version is attached.
There has been some significant changes to the Category Groups which now includes a Modern "Cannonball run" Group F

The title of the Proxy will be "Great Road & Rally Slot Car Proxy Race"

Additionally the motor orientation will be different for some Groups.
I will need a little more time to check through everything again and comments or recommendations are still welcome, but hope to change the Status from a Draft proposal to launching it as an active Proxy Event after the 1st August.

Can you start a bespoke thread for this please Graham as the updated rules are now on page 42

I have deleted all the older versions of this proxy rules on the thread, so only this current proposal should be visible now.

I will be starting a new thread for the new proxy in August, so not long to wait.

I have made what I think is the last changes to the Draft proposal before the official launch in a couple of weeks time.

 I decided to revise the criteria for the list of eligible motors, I decided to have the list to include the motors which are typically fitted to the available Rally and Road RTR cars, so I have increased the motors available to be used to include all with a Maximum rpm of 25K and which have a maximum "Magnetic downforce limit" as measured directly by me of 2.0 grams on the SRC test unit. Interestingly even some SCX RF/RX motor types tested at 2.0
As this Proxy is expected to have a higher proportion of Rally style Stages, then it makes sense to make this "Magnetic Traction limitation" the main characteristic on which the choice of motors are based on, especially as there is no track clearance limit as previously used.

Also with the recently added Cannonball Group of Cars, the axle width has been increased in order to permit some of the wider available GT cars which we might expect.

I am feeling content with the above but until after the 1st August this remains a proposal Draft document .

Years ago when we set our own motor magnetic effect limit it was based on SCX motors which average out at 25g at track ride height on our home made magnet checker.

Can we include Cahoza motors….. I’ll leave it at that.

I have tested both the 21.5K & 25K Cahoza motors and unfortunately they are both above the 2grams downforce limit, (actually 2.10 and 2.15 respectively.)
They are very open case S-Can motors which I think is enhancing their magnetic traction performance.
