2021 SCHUMACHER LD2 CNC CHASSIS
My modern club racer for quite a few years. It started life as an LD1, then was upgraded to an LD2.
I did a lot of different chassis for this car, and this is the ultimate evolution: a CNC machined alumnium chassis with a titanium spine.
I had also tried a magnesium version to increase lateral flex while maintaining longitunal strength with the titanium spine but that was not as successful, especially on jumps.
