This is my first posting here. I signed up a few months ago, and lost the website address, and was re-directed here by Martin Field.
I've been reading with great interest the post on this proxy section about a Pre War GP Proxy Series. Unfortunately, Ken has decided not to run the series because of various circumstances, so I was interested to see if there would be interest in running a series of proxy races for these cars, and, if sufficient entry, organising such a championship.
There was a discussion on the previous thread, as regards to which cars should be eligible. Throwing my hat into the ring, I would like to suggest we follow the regulations set out for the one and only meeting ran at the Donington Slot Car Festival in 2010. They can be seen below. These give a clear set of cars, and sizings, which could be the basis for a championship. Personally, I would change the rules to allows hard bodied cars only.
I'm thinking of perhaps five-six rounds, perhaps based in Europe only, to save on postage cost, and in turn, entry fees. The championship rounds of the late 1930s were based only in Europe (four races for example in 1938), followed by numerous non-championship races, held again mainly in Europe, apart from Brazil and Tripoli. At least for the first year. Anyway, feedback is appreciated-

Jon, why hard body only? What's wrong with balsa or vacform if they're accurate? If you are allowing people to be 2mm out on the wheelbase, I see no big fuss to be made about the body! A well made balsa body could be as light as a vac-form. The only objection I can see to vac-forms is that they became the norm for blob body racing, which PreWar cars were never used for. A vac-form made into a female mould could even have good louvres. It's time we shook off this anti vac-form nonsense and faced the challenge of making nice, accurate bodies that way.
I totally agree with Martin. And here we have this wheel size nonsense again, for everything you 're working on scale, except wheels Also the the tyre brand, why must it specific be Ortmann, why not just say Polyurethane tyres? cheers, Danny
I think if there were to be a mainly highly detailed almost Concours turn-out, then lower powered motors might make sense, but with even 50K motors being not all that expensive, I say leave the motor choice and just race. It will soon become obvious what works and what merely fits a concours entrant. Too much restriction will stifle these events in the end. As to tyres, just say "No sponge or silicon" for track reasons, otherwise give a +or- limit on scale tyre sizes. Something like the old ECRA Scrutineers' Guide would have all the tyre sizes for older cars. I have one here if anyone would like to know what's in it.

I will add my 2 cents worth. Hard bodies , rubber or eurethane tyres and one suitable motor. Allowing open choice motors makes it hard for all entrants. The choice will depend on what tracks are finally involved in this event.

The suggested rules are certainly a step in the right direction. A few observations and comments.
The original Donington table of eligible cars is excellent from my point of view, with the inclusion of voiturettes at last. The inclusion of the Trossi-Monaco might might bring comments as (according to my reference) it did not race or indeed practice, it was simply 'tested' prior to the 1935 Italian Grand Prix. Personally, I'd accept it.
Tyres. In this area I think a balance between scale sizes and availability is needed. The minimum permitted diameters mean for example that most of the smaller cars, and several of the earlier cars must have oversized tyres to be acceptable. I would suggest minimums of 20.5mm fronts and 22.5mm rears. I also symathize with Stubbo. Personally I can get by with the maximum tyre widths, but since many entriants would wish to use the PP wheels and tyres, perhaps an alteration should be considered. A last comment on tyres. One rear tyre I use is 7mm wide with nice rounded tyre walls, the other is 6.6mm wide with almost flat walls. When I sand down the latter tyres, the tread width ends up wider than that on the 7mm tyres.

Thanks for the observations. I'm sure that extending the tyre width max to 7mm isn't a problem.
As regards to the motors, I want to keep the rules as open and as fair as possible for all. However, I'd prefer to leave it as is. At the retro meetings I attend, the Scaleauto motors are very popular, and beat the rewound's and hot motors hands down. These are also very reasonably priced.
I like Peters suggestion on 20.5 and 22.5 tyre diameters.
Would anyone have any objection or comments to the above?
Jon, why would a Scaleauto standard motor beat a rewind/hot motor? Are you saying that over a certain speed a car becomes too difficult to drive? I applaud you leaving the motor choice free for those who want to try something different. I deplore the ban on vac-forms. Short sighted and playing to a narrow minded audience. You'll be a politician one day. Supposing I came up with a push moulded styrene body? Just to be cussed, like?
Are wheel and tyres available in this size and where might one acquire them? 4.3mm is very narrow. And how high would they be to scale?
This is what I have to choose from
All fit within the amended rule , the one on the right is the obvious choice out of the three. At least the contact patch is 4mm. I guess there has to be some grace in the transition from 1:1 scale down to 1:32. These cars are traveling much, much faster than the real thing in scale terms. And they are a long way off scale in tems of weight.
