Scalextric Javelin: C3921 & C4058 - End Bell Colour

[Slalom4me]

A question for owners of (or those with access to) the Yellow #68 (C3921) and Blue Alabama Trooper (C4058) Javelins offered by Scalextric.

What colour is the end bell of the stock factory motor ?

Are they green like the end bell in my #6 Penske Donohue (C3731) ? Or are they purple (C3921) and black (C4058) ?

Ok , I have the yellow #68 Javelin and checked the end bell color , it is clear/white . Not sure if it matters

[HomeRacingWorld]

It doesn't matter. Tested both. Same motor.

Thank you for the reply. I hope a few more contributors join in.

As to whether end bell colour matters.

If the consensus in this thread is that common factory Javelin end bell colours are green or white, then curiosity might be aroused amongst inquiring minds if someone shows up to race w/ a Javelin possessing a non-green/white end bell and displaying inexplicably greater speed than our cars.

If they do, it's not the motor.

Motors tested.

Motors tested...as I think I just stated.

Perhaps the "NON" qualifier doesn't stand out in my previous post.

I see the results of your test of Green vs White stock motors in the link you provided. What I am proposing is that maybe a car having a black end bell might be the beneficiary of an illicit (for stock classes) motor swap. - something w/ more advertised RPM, perhaps 20K or more ...

I have 10/27 gearing (up from 9/27 stk). The cars in question have as much or more top speed as mine, and decidedly more acceleration: near instant, versus mine's somewhat belabored climb up to peak speed.

FWIW-a 10/27 gearing will give you slower acceleration...
More speed, but longer to get there

[drvanski]

My cop car has the black endbell. My #6 has the green endbell. I'd call the cops - but they're already on the scene. I'm here all week...

If someone is cheating at toy car racing, they have other problems.

Thank you,

As #40 The Gipper was known to say, "Trust, but Verify ! "

Regarding gearing. For the stock motor with the factory 9/27 ratio in my #6, RPM peaked 1/2 way down our main straight - the motor droned along the rest of the straight to the braking zone . Swapping to the numerically lower 10/27 ratio resulted in RPM peaking right before the braking zone with vMax being correspondingly higher.

The cars in question peaked earlier but carried speed equivalent to my car (10/27).

An 18K FC-130 motor driving a 10/27 ratio produces an axle speed of 6,667 RPM; a 20K motor driving a 9/27 ratio produces an axle speed of, wait for it, 6,667 RPM. An"18K" Scalextric motor can be expected to log a torque measurement in the vicinity of 100g/cm; a "20K" aftermarket motor might bump the meter to 150g/cm+.

The black end bell in drvanski's Alabama State Trooper car puts the matter to rest for me.

Racing at our club brings to mind the tag line for an old TV show: "...everything is made up and the points don't matter." If there HAD been indications of motor swap hanky-panky, I would have just put it down to love of a good laugh received from perplexing others. However, it appears that a black end bell motor is a legitimate factory offering.

Looks like I need to work on making improvements to my break-in and tune-up procedure so as to become more competitive !!

Thanks to all

[drvanski]

The state trooper car has no interior so maybe it’s lighter?

I dont know if you can change tires for your racing class. Dont forget tire diameter,(or circumference) also makes a difference in speed of the car.

[Fathead59]

And I agree with Dr , if you have to cheat to have fun with toys you have a deep problem

[ecr]

As my dad used to say "it takes all kinds to make a world"

[Giddyup]

Amongst what has been said, the tire diameter (bigger = faster) and tire compound will make a difference to speed and lap times. Re tires, is everyone running a spec compound? I'd bet not.

Other than gearing, which as been mentioned, you will have a slower response. The other item that hasn't been mentioned is the controller. If you have what I call a whiz bang controller, you can set up the sensitivity to be more immediate and along with some traction controller really dial-in your racing.

[Giddyup]

One other thing I'd suggest, is to ask to see what the other person has done to their car. 95% of the time people will share and show; if they won't show, then ask. If the club is trying to grow and promote membership, retaining people through sharing is common aspect of doing so.

Several things here...
1. you need to make a police car "more competitive"? it's racing?
2. there's at least a 10% production variation in ALL motors testing proves this.
3. if you're taking the time to look for an advantage by splitting hairs in which motor (depending on endbell color) you feel might have an advantage over another could be more usefully spent by practicing on the track you will race on.

And so it's clear to everyone, and most people here I think know this already... We don't do changes in what motor we put in cars based on performance of the motor. We put motors in cars in batches and what's available and most likely cost is the consideration as well as availability in China. NONE of the bigger companies use performance as a consideration.
