I set up my cars on a Scalextric piece of track so I’m also confused about this.  If it’s a SCX issue, I’ve never even seen SCX track so it’s more understandable.

I set up my cars on a Scalextric piece of track so I’m also confused about this.  If it’s a SCX issue, I’ve never even seen SCX track so it’s more understandable.

The old Scalextric Classic track has a shallower slot than the more modern Scalextric Sport, 5mm if memory serves. The SCX track that is being used is more or less the same as Scalextric Classic.

I like Classic track, but the problem is that there are ribs at the bottom of the slot every couple of inches, rather than it being a smooth surface, so a guide that is too deep slams into the ribs, and you either risk damaging the guide mount or causing a big deslot. It's basically impossible to drive.

From BARacer's report it sounds like some of the competitors have put an angle on the front of their guide, which is what I also do. This makes the cars bounce over the ribs, which isn't ideal, but at least leaves the guide at its original depth for other types of track.

I guess this is all part of a rally proxy, racing on different terrain.

We as a club stopped using Scaley classic track for Slot Rally about 4 or 5 years ago because of the problems.

In my opinion, Scalextric and SCX Classic track should always be part of any multi-stage rally event. Many of the legendary Slot Rally stages in the UK and Spain are made from classic track. However, the shallow slot does always seem to catch people out. Surely that’s part of the challenge - and part of the fun! 

Learn from this experience, note the cars that did get round the Classic track stages and use a suitable guide next time. Both my Subaru and Porsche 911SC have Ninco sprung guides - designed to work with classic track. They both ran very well on yesterday’s stage - and the shallow guide hasn’t hampered them on the previous 4 stages either.

I would say due to the sheer amount of cars that suffered, this is an issue.
As far as I know, my cars complied with he recommended guide sizes, and I expect so did most, if not, all the others.
TBH the track was replaced by Scalextric over 20 years ago.
But, I can see why it would still be a mainstay for rally track fans, as there are not many plastic track rally options.

I will take it as part of the learning curve for entering proxies.
Also thank you BARacer for persevering with the round despite the difficulties.

Are any further events scheduled to be run on SCX or Classic track ?

[OXO cube]

the Goldrock rally section will be run on scx rally loops and classic track due to the specific rally track pieces
both my cars were tested on these track parts and encountered no problem during testing here
but my track is very old and very well used so maybe has a slightly more worn track slot depth ? maybe ?
the tarmac section will be run on scally sport so should be no problem there 
just an fyi

I've got loads of Scalextric Classic track. I remember it catching me out, a few years ago, when I used adaptor straight to mix Sport and Classic. My Escort Mk1, just stopped dead! Luckily, no damage.

Has anyone tried routing the Classic track slot, 1mm deeper? Something I have been considering doing. Yes, I expect it will weaken the track, but if it is going on a permanent layout base board, this should not be an issue.

I must admit, I always chamfer the front of my guide blade, just in case there is a slot depth issue, on rally stages I have no personal experience of. Certainly, one of my cars was touching the bottom of the Classic slot, on this stage, but the chamfered blade prevented any real issues. 

I must admit that the "6mm max flag depth" rule, made me expect that all stages had slot depths for 6mm or greater.

Hi all. 

The remaining legs have been run. More of the same. I am off slot racing now for the afternoon, so will publish the final results, and some more commentary, early evening.

Sounds like that was a particularly tricky introduction to running a Proxy event, well done for persevering Jeremy 

The following two stages will be my 4 lane permanent Scalextric Sport Track layout,  should suit the tarmac style cars, but will be good for all entries. 
My second stage is planned as SCX ice effect track, combined with Scalextric Sport Track, not the very old classic track. If I encounter the same sort of problems as Jeremy I will swop to a combination of Scalextric Sport and Ninco off road track, but without the obstacles,  obviously 

Regards the older Scalextric classic track we did try to incorporate two of  the wonderful Goodwood chicanes, fitted back-to-back,  on the 4 lane sport layout.  They proved to be a nightmare, simply because of the depth of the slot, which as Jason has noted is shallower than Sport track. 

My two entries both have Ninco sprung guides, and appeared to cope OK yesterday.  
It's tricky. You get a good variety of track pieces in the old classic track,  it's super cheap, gives good grip (especially for a rally event ) but it is very old, and really outdated.   I will try my SCX ice effect track stage, but have the option to change if necessary.

 Good morning,
i had time to review the results and the measurements I made on the cars.

Rally Schedule is in the leading page but in case you missed it, this list the tracks where Scalextric or SCX track is in use.

Rally Slotting Schedule.pdf Size: 18.13 KB  Downloads: 99

So this is where more pain is lightly to be inflicted to some of the teams.

Rules
Guide requirements as "strongly advisable" 
Depth Max 6mm
width Max 1.5mm
Length Max 20mm

This is an rule that is difficult to enforce as there will always be those who propose that guides outside these limits can be used, if they fit thicker braids, have recessed guide location within the chassis, the guide is higher than the front wheels etc,etc,etc

But I did seek to persuade entrants to use the appropriate guides (eg 6mm guides from NSR, Avant or Ninco) and posted photos of the recommended guides. 

However I did not include it in the mandatory dimensional list of compliance requirements  (as in the scrutineer reports) for the reasons above.

But I did measure many of the cars, hoping to avoid out and out failures on the track, some arrived too late to do other than the basic dimensional measurements.

So here are some over spec guides:
Groundhogs - Alfa Romeo (D 6.7mm)
ManxAndy - Jaguar XK120 (D 6.4mm & L 21mm)
Savage GT - BMW M1 (D 6.4mm & L 20.4mm)
Novissime - Audi Quattro (D 6.6mm W1.7mm & L 22.2mm)
Brumos - Porsche 914/6 (D 6.4mm & L 21.2mm)
James@wye Valley- Porsche 914/6 (D 6.5mm & L 21.4mm)
ALS - Alfa Romeo (D6.5mm & L21)
BARacer -Triumph TR7 ( D 6.2mm & L21.4)
ManxKevin Jaguar XK120 (W 1.6mm)
Mountain View - Lancia Delta ( W 1.7mm)
Team Cube -Ferrari 308 ( L 20.4mm)
SSRC - Triumph TR7 (D 6.7mm)
Bangers Racing - Citroen Saxo ( L20.4mm)

I guess I could have disqualified all of these and more, but on the otherhand taking the pragmatic point of view, these "out of spec" guides are self penalising when we get to these types of Rally tracks, but probably have the advantage over the "in spec" guides on the less demanding tracks.

I would also add that very loose guides which can rock from front to back can also be a problem in these SCX tracks even when they are within the specified limits
