Before I start, I should mention that all 4 of my Scalextric cars are (probably) over 15 years old - and the last time I had a Scalextric set IIRC it was Triang and Magnetraction hadn't been thought of yet.

The secondhand Scalextric set I bought a couple of months ago came with a pair of 1990s F1 cars (Williams Renault/Benetton Renault), a Laguna BTCC car and a Megane rally car (the set was Renault branded). The set had had little use and the first time I used it I didn't even bother cleaning the rails, so the cars ought to be barely run-in. The F1 cars aren't too bad on the track, especially since I fitted silicon tyres, but the two saloons tail-slide all over the place and are noisy. TBH I was reasonably happy with it all and I thought that if I put some decent tyres on the saloons all would be fine.

Then yesterday I thought I'd start adding to my collection of cars. I bought the SCX Morgan Aero 8 and Porsche 997. To say they blew me away is an understatement. If anything, the magnets are too strong! These two cars lapped over 1 second quicker than the Scalextric F1s straight out of the box!! Has slot car technology really improved that much over the last 15, or so, years? OK, so the SCX cars aren't perfect but they are far better than I had expected. I can't wait to get another pair now. biggrin.gif (I want the Talbot Sunbeam Lotus and a mkII Escort next, but I've got a seven week wait for them) My "wanted" list is something like 60/40 Scalextric/SCX, but now I may have to change that and make it more SCX-biased.

Now, I'm loathe to give-up on my Scalextric cars - particularly as the plan was to have plenty of cars so that I don't get too bored with the whole slot car scene too quickly. My Scalextric magnets do still have some "pull", but nowhere near the same as my new SCX cars. So..... Can I get stronger magnets for the Scalextric cars? Or are they likely to just need new standard ones? Do the magnets deteriorate with age, even if the cars don't get much use? I've seen magnets on eBay, but haven't yet taken much notice of them. Any recommendations of good ones, or ones to avoid?

Actually, the SCX cars came with the magnets in the down position and I've adjusted them up. I tried the cars with no magnets and they were worse on the track than the Scalextric cars. smile.gif

TIA
Stuart.

Hi mate.

Your magnets in the older cars do wear out & changing them for new ones should be an easy job, ebay is a good source.

How come the long wait for the escort & sunbeam ?. I dont know if the sale is still on but modelzone is/was selling both of them cars for £20 each. Im going to the metro centre today & will report back after I have spent a fortune rolleyes.gif . I got the sunbeam from the Newcastle store a few weeks ago.

I love most SCX cars but in the past quality control was a bit lacking, I have had several motors fail on me. However recentley they have upped their game & the recent cars are all very good. In the past it was very common for the lights to blow if you had a scaley track as the voltage was a bit to high for the car, but they have sorted that out.

Cheers Paul.

Ah, the happy days before magnets ruled the world. Nothing better than waiting for someone's tail to slide off line and give 'em a gentle nudge out of the slot... tell that to the kids of today rolleyes.gif Sorry, can't help I'm afraid. Have had a few moderm cars which generally sit in their boxes completely unused whilst the old non magnet ones get used (or they would if I could find them lol) biggrin.gif

Good luck.


PS are the SCX lights blowing a major issue or easily sorted - I have a rather nice McRae Jr Evo I'd like to see running on my scaley track, but I had it as a gift in around '02 and would be pretty cut up if it got damaged?

Cheers.

Tail slides are where it's at cool.gif


Magnets usually deteriorate with heat and being knocked, it's also possible that the old ones were never as strong as the ones in your new SCX cars?

They're your cars so enjoy experimenting; different magnets, different positions in the chassis, trying stuff out is half the fun

Hello Stuart,

Nice to hear about your re-discovery of slot cars. I remember when I got back into slot cars four years ago - trying out the different manufacturers was both fun and interesting.

I have to say, in my experience, my Scalextric cars have always been marginally quicker than my SCX ones. You mention that your current Scalextric cars are all around 15 years old - I think you'll be pleasantly surprised once you pick up a brand new Scalextric model. Of course it varies from model to model, for example, my two Maserati MC12 models are two of the slowest cars I own (they're just too tail-happy), while some of the Le Mans Prototype models (Audi R10, Peugeot 908) have such strong magnets they're among the quickest cars in my collection.

Then, there are so many other makes to consider. My Ninco cars are all pretty quick, while Slot.it are by far my favourite models in terms of performance, looks and build quality).

It depends on the size/type of track you plan to run on. My Avant Slot Pescarolo Sport seems to have a monster under the bonnet and - in a straight line - would probably be one of the fastest cars I own, but I don't have the space to create a straight long enough to find out! Further to this, I have one NSR model, but I've never really been able to run this on my lumpy old plastic track as it's ride height is so low.

My advice is buy cars because you like them (my collection is based on one guiding principal - buy a car if it, or its livery, is 'cool'!) and have fun trying the different manufacturers.

I assume you mean worse than the Scalextric cars with their magnets still in. That is probably the advantage of SCX cars, their non-mag performance.

As people have already said, your Scalextric cars are from a gentler magnet era, so newer ones will be even more stuck down.

Time to start looking for new magnets, then. I've got a few other slot items I want off eBay so I'll probably have a look this evening, while Wor Lass is watching the soaps - if I can tear myself away from the attic!

I've spent some more time in the attic this morning. biggrin.gif

How do the magnets come out? I've measured the length and width as best as I can (25x8mm) but what about the thickness?

I'm in the process of doing some back-to-back lap timing. I'll post the results later.

On the SCX cars you can adjust the magnet pull by adjusting the two screws on the magnet holder under the car.

To get more magnet pull loosen the screws (but not so much that the holder starts to rub on the track).

To get less magnet pull, screw the whole magnet holder with the magnet out of the car, turn the holder 180 degrees and re-assemble. This allows the magnet holder to be adjusted further into the chassis, hence making the magnet effect weaker.

Does your Scalextric cars have brown or shiny magnets? I suspect you got cars with the old weak brown magnets mounted under the chassis, if so then there are no direct replacement magnets to buy, but you can always hotglue a new type magnet inside the chassis to increase the magnetic pull.

If you should ever get tired of the stuck down feeling, insane speeds and hard crashes that modern magnets tend to make, then put them on your fridge door and come over to the no-mag world of sticky urethane tires. balancing weights lower track voltage wink.gif

They have the brown magnets.

I don't know if anyone's remotely interested, but here goes anyway........

First session. 20 laps. All cars run on lane 2 using the same hand controller.

Scalextric F1 cars. Totally standard, with the exception of Scalextric Sport silicon rear tyres.
Williams. Best lap 7.8sec. 7 de-slots
Benetton. Best lap 7.7sec. 4 de-slots

Scalextric Saloons. Totally standard. New Scalextric 11mm grooved rubber tyres.
Megane. Best lap 8.6sec. 11 de-slots
Laguna. Best lap 8.8sec. 8 de-slots

SCX GT3s. Standard. Magnets in highest position.
Porsche. Best lap 8.0sec. 2 de-slots
Morgan. Best lap 8.1sec. 6 de-slots

I then decided to see if I could quieten the saloons in particular and make them run a bit smoother. I don't know if I should have done this, but all 4 Scalextric cars got WD40 in the rear axle bearings and the motor shaft bushes.

Second session. 20 laps. All cars run on lane 2 using the same hand controller.

Scalextric F1 cars.
Williams. Best lap 7.6sec. 4 de-slots
Benetton. Best lap 7.4sec. 2 de-slots

Scalextric Saloons.
Megane. Best lap 8.5sec. 5 de-slots
Laguna. Best lap 8.5sec. 7 de-slots

SCX GT3s.
Porsche. Best lap 7.8sec. 1 de-slot
Morgan. Best lap 8.1sec. 7 de-slots

Third session. 20 laps. All cars run on lane 2 using the same hand controller.

Scalextric Saloons. Now with (badly fitting) Scalectric Sport silicon 8mm wide slicks on rear.
Megane. Best lap 8.3sec. 5 de-slots
Laguna. Best lap 8.1sec. 2 de-slots

SCX GT3s. Magnets now in lowest position.
Porsche. Best lap 7.3sec. 3 de-slots
Morgan. Best lap 7.2sec. 5 de-slots


TBH, I'm not sure what all this means but it's given me something to do while Wor Lass has been at work. biggrin.gif

I think I've decided to do nothing more until I've tried the urathene(sp?) tyres on the Megane and Laguna. Depending on the results of that experiment, I'll then decide if I'm going to buy new magnets for all the Scalextric cars or more of Paul's tyres to go on the F1 cars.

The lap times look ok, but the amount of de-slots seam a bit much mate ?.

Are you pushing very hard when your racing, thats the thing with magnet racing as you do not get much of a clue that the car is at the limit of grip until it to late. I am not a big fan of the scaley silicone tyres, they can be a bad fit on normal wheels & a lot of people say they can have a bad effect on your track, taking off any rubber laid down by your normal tyres. I can not confirm this as its only a rumour wink.gif

Oiling up the gears & bearings will do you cars the world of good, your lap times got better & for some reason less de-slots ohmy.gif . I would use 3 in 1 oil instead of WD40. Keep the WD40 for cleaning your track, Light dusting on all of the track, pinch the wife's tea towel & wipe it all off. Wait a short while then have a play.

Yes, I do push hard. I don't think I've had one 20 lap yet where I haven't de-slotted. I need to learn to slow down.

Running a car with Silicon is bad news for any car that is rubber shod. You create a film on the track that makes it very slippery. Takes a while to get it back to "normal", if that's your normal.


Many a man has been strung up and their controllers shoved up their exhaust pipes, for ruining an entire meeting at club level, by running a car around with silicon tyres on biggrin.gif
On a 10 sec lap you increase lap times by about 1.5 secs and your car resembles a wind-screen wiper ohmy.gif

I found that with magnets the car sticks to the track like chewing gum to the cat, until it doesn't stick...

But I'm not good enough to drive on that narrow limit tongue.gif
