3 cars per entrant...is a pleasant surprise  

Why only plastic chassis?  Is this because SRGB is plastic only?  This rule is definitely going to count one regular entrant out.

There are no team awards, so it would be a maximum of 3 cars if an entrant wishes. 

The reasoning regarding Metal or B&W chassis is that they do offer improved stability over non metal chassis, and in a proxy where stability is going to be the overwhelming benefit for success ( compared to others) I think this rule is important, in the same way that the motors will be restricted because of magnetic traction on metal contact rail tracks. The B&W chassis are not commercially available ( except Revoslots) so these chassis are exclusive to only one or two persons.
I have permitted them in a different proxy context, where I felt they did not offer such a significant benefit, and would do so again but not this one. And I believe that it is not necessary to have them included just for one persons preference. So I am sorry to that person if he can only build metal chassis cars, but that’s the ruling.

I like it...but hope as it's all road based that we're not going to see offroad plastic tracks.

There will not be any tracks with obstacles for the cars to negotiate, it is possible that some short sections of track might be used with Ninco/ SCX track surface included (as it is with the current National Rally tracks) but it would not be encouraged as a dominant part of a Round.

Where are we seeing B&W chassis having an unfair advantage on plastic tracks?

...and B&W chassis are commercially available if you ask the builder in question he'll make one

In terms of stability, there is no doubt that it is advantageous from experience in running these proxies. If it is a sprint type racing with club tracks with long straights and generous curves then perhaps not such a big advantage if the motor rpm is restricted. If the motor rpm not restricted then they have a very big advantage, I know as I race in some National Events where there is unrestricted use of them.

I have tried to get builders to make me B&W chassis previously, basically advice on how to make one, but you will be lucky to find anyone who does this as a commercial service. But generally speaking apart from maybe a few available from outside the UK, they are not generally available at your nearest Slot Car stockist.

What's the link for B&W chassis please? I'm not familiar with them.

B&W is abbreviation for  "Brass & Wire"

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 thought you had posted photos of the 70 Camaro and Cuba you were making, but yes I am fairly certain the Camaro 69 still qualifies, as does the Porsche 934 (But who makes one ?)

I thought “at least 15.8mm, unless smaller ones were fitted as standard” seemed sensible. I am not going to penalise cars for this aspect on scrutinising, but if I think the rule has been abused, then there may be a time penalty applied at the end.

Regarding B&W chassis, as explained it is just not appropriate for this proxy. And we never get more than 3 such built cars ( mostly 2 from the same entrant).
Another time I could accommodate them, but not for this proxy,

[KensRedZed]

Graham,

Thank you very kindly for the explanation. They're known as brass chassis around here.

No problem about the B&W restriction. However, these aluminum chassis would make everyone's head spin. 

I'm just kidding around. I'm not really into proxy racing. Best of luck to the host and all the racers!

Fly makes the 934 and RSR.  My 70 Camaro was eliminated when you ruled no brass along with my 250 GTO, 250LM, 550 Spyder, GTI, and Porsche 904.?  I have a Richard Mack chassis Ferrari 330GT I assume it’s out also.
