I'm isolated in regards to this unknown information What voltage what was the track surface what was the motor configuration what body what was the weight what was the gear ratio what was the pole configuration 3, 5. or 7 pole what magnets what weight

Also in the Texas area if any kind hobbiest can contact Tim Crosslin for me please pass this message my email is clay3680t@.net or contact by  other at 806`=.745-1557.

 

Just in passing consider this we have a 1/24 scale record in a straight line.

to do a world land speed scale record for 1 mile would  require a straight line pass for 220 ft. Obviously most slot racing drag tracks established with a scale 55 ft drag track plus a 15 to 20 extra ft for a run down capture is  most certainly an the most common approach.

however consider a pi approach of a  circular track in an equal amount of 220 ft say at a 70 degree  continuous circular track.

to keep safety at a premium a circular arc would cover the lane with a very tuff plastic tube permanently guarding that  path way hemisphere.

also consider this, two methods of qualifying run time can be  considered,

a dead start run time or a one lap start  up time.  the track=  about  71.85  ft. or safely at 72 ft,

 be worth? 2 runs back to back under an average of . 2 seconds per lap

 

consider a track voltage of 24 volts no more          the track would be a one lane

 

so say all you slot car dragster racers . what kind of incentive say $10,000 to the first  to break ,2 saconds per lap with a 2 lap passes one running cw and the second ccw best regards 357 rewinder

What voltage what was the track surface what was the motor configuration what body what was the weight what was the gear ratio what was the pole configuration 3, 5. or 7 pole what magnets what weight

 

 

The quickest time I have heard about that was witnessed is .401 seconds, and a speed of 135 MPH.

Modern drag strips run 16 volts. Giant wire and power taps every couple feet.

The track is MDF mounted to a metal frame that is solid mounted to the floor. Standard epoxy/urethane track paint. Race conditions has tons of glue.

 

The best I have gone is .408 at 132 MPH, so I can give you that info.

Motor is a strap can, quad cobalt magnets at .450x.450, standard 15t 24 Pro Slot Drag Arm.

Sonic 12/52 lightened gears.

Car weight is 50 grams. Most of the car weight is the motor.

 

For a circle track, if I was going to do it, the car would be more like a wing car than a drag car. One lap to safely get to speed, one lap timing, the motors are going to be trashed and need a rebuild.

Do these cars really need to even get up to speed?

 

Kinda thought that with electric drag cars, as opposed to the gas models for instance, the acceleration is virtually instantaneous...

At Scotts' Speed World, an Estes rocket car ran OVER 300 mph (Triktrax clocked)......ran off the end of the shutdown, out the back door, flew accross the parking lot, and stuck in the chain link fence....ten years ago.

Tires are 1.030x.435

Arm is .445 in a .458 hole

Chassis is a WRP Cobalt motor chassis

.083 thinwall stainless tubing from Mc Master-Carr

Rear axle to guide is 6.125 oon my best car.

Car is 50 grams

Car pix, ahhhhh, not going to happen. I don't have that car any longer. I might have one of my 5.700 cars, will look when I get home.

Thanks Foamy .... that describes it well enough.

 

So @ 6.125 GL it was a FC bodied car not a TF?

After the 1st motor near burned up the nylon parachute we used to slow the cars, we learned to choose a rocket motor with the shortest available burn duration . :dash2:  :laugh2:

Its starting to rain.  Unfortunately, the rain seems to be coming from above, which unfortunately means there are clouds in the sky that will obscure the eclipse.  Fortunately, that provides me with an adequate excuse not to get up at 2-4AM, EDT to view the event.   :D

Estes DID introduce their OWN line of rocket 1/24 drag racers. Saw them at the I-hobby show one year.  Never saw them again.

Yes on the funny car body.

JDS Monte Carlo, Parma/DRS Vette are the main ones.

Taking notes....

Have a 13t/23w Hawk6 "H" Power motor and the Parma Vette bodies....they sure are 'slick'. :D

 

Thanks again Dennis!

Mike Nap recently raised the bar to .401 in a race a Eclipse Raceway. This track produced a previous .401 (Dave Pfaff) some time ago in a test and tune. It was there just waiting for a race.

Say Clay,

 

I like your imaginative approaches to 1/24th land speed record and highest top end. I've been through the ringer of trying to secure commercial/club square footage to support a commercial track and did not make it. My hat is off to those who do. The financial realities of hosting a 220'+ straight run* or a marathon 72' banked circle are daunting especially since they are not amenable to revenue-generating weeknight racing.                                               *A flying mile is just the timed distance. The whole course is more like five miles.

 

The physical reality is that the speed on these tracks would have more to do with the track (grip and amperes) than the cars. One could argue that the fastest 1/24th drag and closed course races (custom King tracks) are already based on track prowess rather than car designs. Maybe that explains why such amazing automotive performance is disregarded, even by the most knowledgeable motorsports fans. Such disregard is ironic in an era when all major motorsports are carefully legislated to even out and reduce the speed of the cars in spite of proven technologies that could increase speed with safety but are routinely banned from the sport. Speed is no longer a significant factor in racing. 

 

That is why I like your imaginative approaches to 1/24th speed records. It IS IMAGINATIVE and imagination is clearly at a premium in our hobby. The image of unlimited speed (albeit synthetic) might attract young racers the way we 'boomers' were drawn in by the imaginative images of slot cars and racing. 

 

Maybe we need to replace Spider Man (a kid with emotional shackles) with the image of Speed Racer (a kid focused on excellence) in the minds of young people. Imagination matters.

Orca's eats Great Whites and a few days ago he did. Chico has called himself many names in the time I've known of him but to me he has always been the silent Killer Whale, Orca!!!

 

Anyone familiar with my writing from the KMR site heard me call this one quite some time ago. Reference "Thoughts on the 3's"  winter of 11/2014 and "Weight, Strength, Balance" 5/2015

 

Power hasn't' been the issue in two decades. Loosing fear of finessing the track's bite was. On over the counter tires for crying out loud! Great job, Chico, and hats off for having the guts.  

 

Here's the video. That enough proof? Enjoy.

I won't cite the national expert I spoke with last year when I asked why there isn't a drag nationals anymore.

 

The answer was twofold. First, an unlimited performance category drives up the price of racing which turns off more people than it encourages. As an engineer I think it is wonderful tech but even in my geek-interest mode I acknowledge that it getting low ET on a given track on given day is a footnote that doesn't promote the hobby much. No disrespect to anybody. Congratulations on getting into the "Threes". 

 

The second reason is that track owners keep the doors open by growing and supporting their local 'tribes' for series racing in a fun environment. Heads-up drag racing rewards the guy spending the most money leaving everybody else unhappy*. Bracket drags are far more positive.

 

(*I had a tack owner tell me the other night that heads-up categories bring out the cry-babies!)  

 

So, much as I may not like it, ultimate speed is not part of racing programs any more. Maybe Bonneville is still an exception?
