Detailed instructions and tips to make a car that will beat all other cars under $250 on eBay
( there are only a few very expensive “Pro” cars that are sold. Many of them are not robust enough for the typical rough handling at youth races. This car is.)
The reason we can make that statement is no other car to date has the TxW “Tuned” Tungsten design that balances the weight on the back wheels of your rail runner. No other design puts over 2.5 oz of tungsten behind the back axle while holding the front wheel to a 17 gram stable weight. AND at the same time moves the back axle to the max location of 5/8″ from the back of the car.




DO NOT BUY this kit unless you can drill the axle holes with tools like below
If you need axle holes, buy the next level kit.

Place bar in your fixture and set wood up against it to get axle hole for back axle in the correct location, 5/8″ from the eventual back of the car.


Place bar on edge of a length of 3M tape
Cut off excess and use to cover plate weights plus a strip across the back where the bar will go

All the rest of the details and tips come with your purchase. You get full instructions on how to get your car up to speed with all the latest design improvements over the last 40 years. The strange thing is while the Pro cars have gotten increasingly faster, the average Cub Pack speed has dropped as the number of folks with tools has dropped. The average car gets the axles pounded in with a hammer into the existing crooked slots, does not add much weight except some worthless zinc, and doesn’t even use any lubrication. This is a District winner from 1980 , 2nd at the Texas State Scouts Jamboree, that has many advanced features that make it a winner still today.

This was the first Cub car to use tungsten, years before it was on the market.

Body is moderately thin.

1/4″ from the back of the car was cut off and has been moved to the front to get the center of gravity farther to the back of the car.

Those two steps continue to win today, including the fastest Cub car in 2018 built with the TxW Pro body and TxW 99.95% tungsten.
