Does anyone know the RPM for Scalextric Sports motors???
Is it the same as the "classic" motors.
What's the difference between a Scaley and a Scaley Sports car???

some problems with our new series just occured and we need to fix it ASAP, before our junior racing ends before summer.
We have to present the new series before so they know what to buy or use for next racing-season

I beleive the sport cars were meant to have a beefier motor, but hornby never ended up doing it, making the motors the same.

Differemces are box, spares, and braids.

This is what I udnerstand, I could, however, be wrong.

salex website says:

QUOTE Mabuchi-S, 18,000 rpm

This is stated on both sport (A serial numbered cars) and non sport cars

there you have it

As explained to me, the cars have a sticker on the motor, a centerless ground axle, brass bushings and a sticker on the chassis. Of course the box and the number card, too. They run $4.00us more than standard.

Cheers!

My Scaley Sport #3 GT40 Mk. II has plastic axle bushings, a "Sport" sticker on the motor, and is slower than my non Sport #6 Gulf GT40.

Go figure.

You may have been misled. Easily done, because the metal bushings are shiny black coated and look very much like plastic but actually aren't.

I also assumed I had not seen correctly when I thought one of my GT40s had no brass bushes Tropi, but I now have 4 'sport' cars without brass bushes, both the older versions (no limited edition plate) and the later ones.
Apart from a nice box, collectors card and a spare button magnet, I think thats it these days, I can not see any difference between Sport and standard axles either to be honest.

I have every Sport model released, simply because I began collecting them and it hurts me litle to continue when I would probably buy one or two of each release anyway. But for me it simply means I get the early releases without waiting for the crystal version.

The actual differences may be there but possibly it would benefit us all if someone could categorically state the 'real'differences' - Adrian? any chance you could clear this up once and for all?

By the way - those Scalextric credit cards supplied in the Sport boxes don't work! I tried them in many bank automats and they all get regected

TI have to admit that I haven't carefully checked every single car I have and might be in error.

This is very interesting and really is deserving of clarification by Scalextric. Not just deserving, but perhaps very necessary after advertised descriptions of the past.

I've heard loads of reports that sport cars just aren't as quick as regular ones. Maybe it's acunning marketing ploy, thought I can't see what it might be...

Hi

The scaleys I have taken apart vary with timing plus/minus some 15 degrees. So bad that some run better BACKWARDS.

I also run them through a "mule". A simple test bed that allows me to just pop the motor in. At 3:1 gearing in the mule, stock motors will dyno between 26 and 32 kph. There is no mechanical difference or dyno difference between Scaley, scaley sport, Scale auto replacments, MRRC, Fly and so on motors.

They all fall inside that same range.

Interesting, Professor, that you mention 15 degrees. Some time ago I was discussing the large variance between Mabuchi motors lately. My local Prof. said he routinely sees them running +/- 10%. He also explained that he and other distributors approached Mabuci to ask if they would please increase their motor's timing 15 degrees and Mabuchi wouldn't hear of it. I am seeing a three tenths to five tenths lap time delta between cars purchased from the same lot at the same time. It's getting so that I keep new Slot-it motors on the shelf to stay competitive. Just adds to the rising cost of going fast, I guess. Perhaps Scaley and the others could offer cars without magnets and motors for less money, as they lately lose those components prior to real competition anyway. (Enough whining ,Harry)


Cheers!

I'll give a closer inspection. Thanks for the tip.

Duh...I'm new around these parts. Would someone please explain this "timing" thing to me, please?

Thanks a lot,

I deliberately bumped this up as it's an interesting subject and it would be great if one of our motor specialists could do a potted rundown on it.
I would have a crack myself, but would feel extremely presumptuous (and justifiably nervous!) simply paraphrasing stuff that I only learned 2nd-hand from some of the genuine experts we are fortunate to have here!
Better to have it straight from the horse's mouth.

Hi

Arm timing...

This is advance on the commutator ahead of the stack. Brushes mount in various ways, I wont go into this. What we are talking about is that normally, a com would have the contacts centered in the stack so that the motor would run the same in either direction.
Advancing the commutator, or retarding the commutator would make the motor run faster in THAT direction. Within limits, the more advance, the more speed and power but also the more heat(usually from parasite currents). At a certain point, it is all heat and no more power.

The modern scaley S cans are sloppy. there is a built in "fudge factor" of several degrees in how the com mounts, how much it can move when the stack it wound, how much is in the design of the brush mount, how precisiely the endbell mounts. This means that most of the cheap buck(or euro) motors can be all over the place from BACKWARDS to very good for the wind and everything in between.

Relating to the other thread about RPM. You can test motors any way you want and getnumbers all over the place. My friend larry shepard is racing in Northern California in a 1/24 class using flexi frames to fit scale bodies, and discovered his required Falcon motor was faster backwards. Did some real surgury to make it work and has had a bunch of people upset.
