Jason I agree fully about the idea of needing torsional strength vs longitudinal strength. This was the reason for fabbing the second plate. The plate I run now is true definition of Quasi Isotropic and balanced. With the layup having equal strength in all directions and plys stacked symmetrically
This is with a woven fabric, I forget but think it is a 4 harness satin weave. Being woven the fabric has both warp and fill fibers. The warp and fill strengths were close to equal, but not exactly. Therfore the reason to use the above layup schedule to obtain the equal strength in all directions and balancing the the plys to have identical effect regardless of which side becomes the upper surface.
The second plate version is not a Quasi Isotropic layup, as it does not have equal strength in all directions, though is balanced via it being symmetric.
This is in no way quasi as it does not offer equal strength in all directions.
It does however reduce weight while maintaining the higher level of torsional stiffness.
I had, and still do consider the idea of a lipped edge chassis. Unfortunately time doesn't exist right now for drawing it and then having the forms machined. The tragic part of all this handmade stuff becomes spares, now it's not as if I can break something and just pick one up to replace it, but then again, from previous failure of oem stuff, stregth is added to allow endurance.
As for the fishing pole, I won't disagree, I'm sure there were also some early tennis rackets too, but for the most part Carbon was fairly common in RC long before it bacame mainstream in other hobby areas.
And to see the new methods of producing carbon products using nanofibre methods makes cutting a carbonfibre plate appear antiquated.
I'll try for a photo, no guarantees. It will be a bit as the car is undergoing some mods in other areas.
BTW Jason, if I ever get to a State race you are welcome to check the thing out hands on. If nothing else this is just a learning curve to decide what to buy next time.
