Jerry and Chuck Gambo came by earlier on some other business, so to celebrate his car making 20 hrs. of running with zero parts replacements or failures, I had Jerry race aganst Chuck, driving one of my regular rental cars.

Cool video... great sound too. zzzzZZZZZzzzzzzzzZZZZZZ

20 hours

[MSwiss]

Well, I had a bunch of other crapola to do, so I gutted it out, to make it to the 24 hrs.

The last run to 24 hrs. was 3 hrs. and 35 minutes straight.

24 hrs. of running with zero parts replacement or parts failure.

Only work performed on the car was oiling, cleaning the braid and bottom of chassis,
and trimming up the nose of the body so I wouldn't have to listen to it scraping, which got worse as
the braid "thinned out", quite a bit, at the end. LOL

The car still has .066" clearance.
It started with approx. .080".

Click on the below video to see the car as it makes 24 hrs.

Note the monitor.

The car, on my "hard to count cars with slow motors", Lanemaster system, finally started counting right before Jerry and Chuck came by, at about 19 1/2 hrs.

The "best time" of 7.179 was when it managed to count twice in a row , for a complete lap,
at about the 22 hr. mark.

The 79.487 was right near the end, and represents an 11 lap count, for a 7.226 average.

The best the car ran, from what I can tell from pacing another car along side it, early on, was a high 7.0,
or low 7.1, when the braid was still decent, and the Wonder tires were the tallest.

BTW, the Buddy Holly song playing in the background on the Oldie's station was totally coincidental.
Honest.








The documentation. On the back of 2 JK RTR boxes and a 4 x 6 index card.

Everything was rounded down.

The car probably has at least 25 hrs. on it, so far.


I was skeptical the braid would make it.

Even as bad as it looked, it didn't seem to affect performance.

The skids definitely got more rubbered up as the braid thinned/wore out.

Last run was 3 hrs. and 35 minutes, hence, the quantity on them.


Most impressive was the gear train.

Despite neither the pinion or spur being angled, it ran the whole 24 hrs., just as I received the car
in the mail. No adjustments what so ever.

Nice.

Parma 's record?

What are you talking about?

Oops! I mean Champion. Thank you for your courteous correction, Mike.

Just 8 hours with G27 20 years ago - got 192 miles on a slow King. Makes 4.4 average laps, wasn't easy without glue. We once tried 24 hours in early 70's with opens - the batteries ran flat after 4 hours. ..

[Rick]

About 350 miles in 24hrs, with the JK rental? Does this sound close to correct?...........

[gotboostedvr6]

that would assume the renters were going full throttle.

[MSwiss]

Yep,about 350 miles.

A little less if you consider the time stopped to oil the car and cleaning the braid.

[MSwiss]

I just had time to take off the body and look at the car a little closer.

The motor brushes appear to be only about 1/3 used, maybe less.

Already mentioned, clearance is .066", down from a starting point of about .080".

The lead wires still look virtually perfect, despite no special looping.

Jerry used a good quality wire and just did a great job soldering them on.

It looks like I'll be listening to this thing go around for awhile, yet.

Well, so much for trying a record, the Guinness Book of World record will not sanction an 80-hour + event.
Here is what they sent me:

· At Guinness World Records, we also only verify records for certain, specific time frames, to avoid an infinitisemal number of possible timed records. Thus, an accomplishment for an 80-hour time frame would not be considered acceptable for our database, as it is not one of our chosen standard time measurements (i.e. 1 minute, 1 hour, 24 hours, 48 hours, etc.)

Please note that the person answering my inquiry misspelled "Infinitesimal" ( ), no big deal nowadays apparently, but care to try for 96 hours?

And Mike, congratulations on a successful run. It shows that a modern slot car fitted with a mild motor can take it!

[MSwiss]

The braid,cleaned and pulled away, to show how little is left.
The super-low amp drawing motor still ran well on these shreds.


The lead wire still looking terrific after 24 hours.


I finally was able to figure out(got lucky) how to get a good shot of the brush wear.
I wish I had a shot of it new to compare, but for 24+ hrs. of use, it looks pretty good to me.

[gotboostedvr6]

Why cant we propose a distance race that can be done by any of us in lets say 6 hours.

It would be a fun competition that can be done at any raceway with lets say 30 days prep time max.

Track owner is the official, all participating racers pay for the event like its a race.
no gear below chassis and .032 min track clearance would have to be maintained during the event in the rear to protect track surface.
Guide flag and braid are the only wear items that may be replaced
Body's may be repaired as needed
Chassis, motor, gears, and body have open rules.

[Gator Bob]

Mike ... you are putting a lot of time in on this test and promotion of this new car.

so.... do you get paid in cash, free rental cars or does Jerry just cover cost of your time and rebraid that one lane?

[MSwiss]

Jerry said there woundn't be any money.

But when I die, on my deathbed, I would receive total consciousness.

So I got that goin' for me..........which is nice.

[John Miller]

Mike, you achieved total consciousness a long time ago. Lol

[MSwiss]

Well, along with total consciousness, Jerry can send me a new pr. of braid.

The ones on the car only lasted 27 hrs. LOL

The car was still running fine, but when I timed it, it slowed down a bit to the 7.3's- 7.4's.

Since the test was to see how long the motor would run, I went ahead and changed them to a new pr. of Big Mama's.

The car immediately was back in the mid 7.1's, and once burnished a bit, the car ran a 7.093, the approx. same time the car was running in the first hr.

BTW, tire clearance is still at .064".

Kinda like a (NES) National Enduro Series with JK rental cars?

How many hours running until you reach total un-'consciousness' .... lol

[MSwiss]

With the new braid on, it's like adding .015" or .020" in guide washers.

With that extra thickness, the car isn't picking up as much rubber (AKA dragging)
and thus is a bit quieter.

With it not being really hot outside, It was slow today at the shop, so I got the car up to 30 hrs. and change.

At the 30 hr. mark, I checked it, and the outside, bank side, clearance is finally down to .062".

[MSwiss]

The White Shadow/JK Rental car just hit 36 hr's.

Still no parts replacement or failure's, just the braid changed at 27 hrs., to keep the car running at max. speed.

The car is still running consistent 7.1's.

Clearance is right at .062" on gear side, a few thou less on the (U.S.) "passenger side".

Will report in again at 48 hrs., or any failure, whatever comes first.

[Gator Bob]

I would think that 'rotating' the tires is an acceptable service item for any future tests.

7.1 at constant speed to stay on.... what will the car run driving it?

.062 to the chassis? Is the gear below the chassis?

[MSwiss]

(1) I would think that 'rotating' the tires is an acceptable service item for any future tests.

(2) 7.1 at constant speed to stay on.... what will the car run driving it?

(3) .062 to the chassis? Is the gear below the chassis?

(1) I'll think about it if clearance becomes an issue. Right now it's not.
The casual eye probably wouldn't detect the slightly less clearance on the non-gear side.

(2) I thought I made it clear. The car is full punched on Orange.
Probably at least 40-1/2 of the 41 hours it's run, has been full punch.

(3) Yes, to the chassis.
The gear hangs a little bit below because the bearing height on the C21 is real low for an RTR.
IE-Jerry ships the regular C21 RTRs with approx. .745" diameter rears.
I'm sure you'll say put a smaller spur on it, but you can't go too small or the pinion
won't engage the spur and still have the motor bolt in, and have the can clear the 1/8" axle.

[Gator Bob]

• K.....
• Whoooow, missed that part. Now there's car I could drive
• ..... then I would say 'how about a bigger pinion too'

[MSwiss]

The car just made it to 48 hrs. / 2 days

Still no parts failures.

Just the one braid change at 27 hrs. to keep the car running smoothly and efficiently.

Lead wire still looks perfect.

Clearance is approx. .055" on the gear side, .050" on the "passenger" side.

Looks like the car still has at least half it's brush length.

There's a bit more gear lash than at the start, but for 48 hrs., spectacular.

Rear axle bushings seem about perfect.

With the tires getting smaller and the "new" braid now having 21 hrs. on it, the car has slowed a bit, but is still running 7.2's.
