A new Tungsten Alloy designed for a low cost weight option.
Tungsten plate is 2.4 mm * 12.7 mm * 43.5 mm or in inches- 0.95″x 0.5″x 1.718″. Engineered to cover the full width of the pinewood body and allow two plates to be placed behind the back axle on standard wheelbase cars, or one plate behind the axle on extended base cars. If you have the use of good tools, you can cut a notch to take 2 or 3 plates in a stack on the back of the car, and finish getting to 5 oz. with more plates taped to the bottom.
All stick on and screw on weights are not the same.
The Density of the alloy and the size of the plate will obviously contribute to plates with different weights.
The present tungsten plates for sale on the internet all run around 0.5 oz. and are close to the same dimensions.
These dimensions do not take advantage of all the space available on the bottom of the car.
The Zinc and Steel plates are so light they can not compete with real tungsten plates for speed.
When you are limited on tools and need to just put plates on the bottom of the car,
you quickly will see how inefficient it is to use undersized plates
or low density plates to control the center of gravity.
No Pro would ever use the cylinders for weights as they need a thicker car
that has too much wind resistance and will not be competitive.
