My kind of rules, Leo!

When we ran the Scalextric class on SRGB a few years back box stock with free tyre choice I used the Quattro S1 (without the wings on it) from the Blomqvist triple pack. Worked pretty well using, I think, Ninco tyres on the back from an NC-1 Megane - it was as quick as a Modern 2WD on some stages. We ran them as a club class for a year or two and the 6R4s and my Quattro were usually up front. Nobody managed to make the Fords work... ah the endless permutations!

My Peugeot hasn't impressed as yet but there aren't any aftermarket tyres readily available in that size and the originals are like zero grips.

Will be interested to see what form the regs take, I quote fancy building a 'wingless' Audi or the Pug.

No it's a standard car, Leo. The S1 is the short wheelbase without wings, the E2 is the short wheelbase with wings. Scalextric made both!

The S1 was only available in the Blomqvist triple pack and as the Scalextric club car C3500. It's mechanically identical to the winged one, just with less plastic hanging off it!

Hi Phil,

The S1 is a sidewinder - same chassis and running gear as the E2. I did a little comparative test tonight between four cars: the inline Peugeot 205, the twin Quattros and the club's own RS200. All on stock tyres, although the Ford's have been oiled and trued recently. The Ford has a ton of weight in it, the S1 Quattro has some lead in the magnet pocket in front of the motor and a dab behind the guide, both the E2 and the Peugeot were no mag no weight fresh from the box.

On our Ninco track the Peugeot took most getting used to - no brakes and very skittish on its narrow track. The E2 certainly felt top heavy with nothing in the chassis and was most prone to de-slotting until you adapted to it. Put one wheel on the track border and the back would drag the guide out of the slot. Compared to my own cars the club's Ford felt unbelievably slow because the weight has killed the acceleration. I like my little S1 and was comfortable with it straight away, even on the shabby standard rubber. Lap times were:

Ford RS200: 15.04s

Quattro S1: 15.38s

Peugeot 205: 15.87s

Quattro E2: 15.89s

I then tried them all on The Mountain. Because it was fettled for Slot Rally GB on that stage the Ford had relatively few problems negotiating it. If a car can handle The Moutain it will be right for most things that a slot rally can throw at it. When you get a troublesome corner weight and momentum will see you through. The S1 Quattro was the same. Both the E2 Quattro and the Peugeot struggled with bumps, changes in elevation and with any spots on the track where there was a slight pinch - both had thicker guides, the Peugeot particularly got wedged in several spots per lap and bottomed out more often.

R1 downhill is a test for anything without a sprung guide or a drop arm. Unless it's full of lead, of course.

This is why the pace notes say "don't cut"!

All in all it rather whetted my appetite. I'd like to try whatever the recommended guide is and some good tyres. They're all good little cars, though.

Thank you!

If there could be a clarification on the eligibility of the S1 please I'd be very grateful. Here are the two types of sidewinder Quattro that have been released undressed for comparison. The weight of the bodies on my scales was 43g for the E2 with the interior and 28g without. The S1 was 37g with the interior and 22g without.

I've been searching for MJK tyres without success. Any guidance on tyre choice would be great for the build please, particularly the size of the chosen rears so I can keep the fronts within 1mm. Same for permitted guide replacement and their sourcing and fitting.

Paintwork I can do, anything else is a dark art!

Thanks for the tip, PG. I've been looking at the tracks and they mainly seem to be routed or Scalextric Sport, so hadn't thought about using a sprung guide yet. I'll drop you a PM!

Hi Phil,

Yes, the S1 debuted in Corsica 1984 and ran as the primary works car until the Olympus Rally of 1985 when the E2 version took over. It stayed in the front line until the end of the Group B era in 1986, making the last appearance of a Quattro in the world championship at the RAC Rally that year.

You've basically got the original long wheelbase Group 4 Quattro in 1981-82, the long wheelbase Group B Quattros the A1 and A2 in 1983-84, the S1 in 1984-85 to try and make the car work better on tarmac and finally the E2 evolution of that car in 1985-86.

So the Scalex sidewinder models cover the 1984-86 period.

Here is some pornography of the real thing in period. By cutting a foot out of the floorpan behind the front seats of the Quattro they actually made the handling worse rather than better. A whopping 63% of the car's weight sat on the front axle and they swapped out the old 400 bhp 10-valve engine for a 500 bhp 20-valve. The cornering technique was to throw it in on the brakes and jump on the gas before the rear end overtook the front. No fun for the drivers but awesome to watch...

Wow those tyres make a difference don't they? Thanks so much to Leo I had a pair of MJKs to try out this evening. I put some Ninco tyres on the front wheels as they were slightly lower profile and, using the same S1 on the same lane with no other changes to the car, the result was:

MJK tyres: 14.69s

Scalextric tyres: 15.38s

So in pure speed terms seven tenths are to be found in the black round bits. On the other hand the car was a lot more nervous and tippy with a lot more 'offs' - although most de-slots were because of the guide being plucked from the track by the general level of hippety-hopping going on as the chassis struggled to comprehend the levels of non-magnetic grip available. Of course that was on Ninco rather than Scalextric Sport or wood, which seem to be the preferred surfaces in WRP, but certainly a sprung guide and some body float are basic requirements.

It's a good game, this.

I'm flattered by the idea my tuning is up to any good... or is that bewildered?

Still got to find a donor car for the final build. My word, the prices people ask these days...!

Hopefully will be able to stat the build before too long. Can I ask, though, how you fix those guide adaptors in place? Is it Araldite or something more technical?

Found a car. Phew.

I made a mistake earlier - there was a one-off appearance on the WRC calendar by the Olympus Rally in America at the end of the 1986 season, after the RAC. So that was the last appearance of the Quattro in a world championship event when John Buffum drove a David Sutton-built S1 to third place (Manx numberplate and all...)

I think that will be the basis of the scheme.

Excellent news. By the way, competition numbers have to be unique so best to register/claim your number as soon as poss (on the other place obvs).

"BigC" had #5 last year.

Leo
Not that worried, I see I'm #8 on the list, which would be nice! I also see that there were some WRP number panels done, so I might well use one of them. I can always add the correct numbers on after the event, or keep them on as a memento! Seems to be the thing to do with historic cars...

Basically Andi reinvented the B-Nova guide replacement without realising!

https://www.slotforum.com/forums/index.php?showtopic=177922&page=2

They're available on Shapeways, Martyn.

Meanwhile I've stripped the Audi as best I can. Have to say it is not easy and not a job I'll do again willingly. Dipped it in meths for three-four hours and the livery turned to a concrete sludge that would not budge (poetic stuff!).

Got some of it off with nail varnish remover but not enough so gave it another meths bath, sanded it, used finest wet & dry and then another meths bath.

It's now in primer and I'll have to rub it down a bit. Should be presentable but wow... no fun at all.

It was also a bit of a dog that I bought. No mirrors or aerial, broken motor retaining clip... if I wasn't stripping it I'd be sending it back. As it is I don't feel too badly about being a bit brutal with it. Oh, and the livery's gone back to Plan A - Michèle Mouton's Pikes Peak car. That was the livery used on random non-WRC events in 1984 so seems fitting! Also I don't have the nice gravel wheels to put under it.

Now to work out how to fit these guide adapters when they arrive...

Thanks PG,

I'll do what I can mechanically but that's not really a forté of mine. I've never changed the guide on a car or anything like that so I'm going to be learning as I go.

It won't be the fastest come what may, so might as well make it as pretty as I can! A few battle scars should look well on it - but I've never had major damage from running cars for hundreds of km or on a full season of SRGB for example.

Andi Rowland's guide converter arrived - dream come true for me! Just slots into place and there you have it: a perfect solution for the technophobe

Meanwhile the bodywork is coming along. I'm afraid it's not up to much at the moment, a bit scruffy by my standards, but given what a beast of a job it turned out to be then with a bit of finishing it will do OK. The decal sheet isn't all that great so no real worries about tweaking it with WRP rally plates etc.
