All bodies on this page are 7″ long and 1-3/4″ wide. These dimensions are the same as the stock Scout Grand Prix bodies. My blocks are made from either Clear Pine or Clear Poplar (depending on the availability of material).
I offer the standard block with the slotted base as well as precision drilled axles holes for both standard and extended wheelbases. If your rules allow the use of an extended wheelbase you can benefit from a more stable ride as well as the advantage of moving your relative Center of Gravity (CG) a bit further back. This will give you a bit more potential energy to release because scootching your CG back raises your mass slightly higher off the ground. Try this – Drop a golf ball on the sidewalk from the height of your shoulder – then try it again with your arm extended way above your head. What happens when it drops from a greater height? How high did each ball bounce? Which one had more energy to release?
The three holes are drilled at the rear for inserting Lead Wire, Tungsten and WuttyTM to weight the car to the 5 oz maximum. The amount of weight that you put in each hole is totally dependent on your car design and your track condition.
