Well here it is.... designing my own upper deck:
The Design
First you'll need the tools of an engineer which consist of pencil, erase, paper, ruler, digital caliper (for precise measurement).
Once you've drew out the design on the paper, it is time to make a photocopy of it for backup incase you screw up the fabrication. Take one of the copy of your design and cut it out. Now you'll need to glue the design onto the material you're going to cut which will be used as a template. The material of you upper deck can be fiber glass, carbon fiber, etc. In my case, I used fiber glass with a copper coat on top to add stiffness compare to pure fiber glass?
Fabrication
Now it is time to cut it out but before that some
safety equipment you'll need. Since we're working with composite, you
will require safety glasses, breather mask (you do not want to breath in these dust fibers), and gloves. Tools to cut the composite, I used a dremel with cutting disk and also diamond coated carving bits. I would suggest cutting the perimeter of the design first, then drill out the mounting holes to test fit the part before moving on. After all the cutting is is done and that part fits, you'll need a small file to smooth out the edges.
Finally mount it onto the car and it looks something like this:
So here is my chassis #2 with Exotek Generation 1 chassis.
I need new tires or scrub these old tires good.... I had absolutely horrible traction compared to chassis #1. Then again when I tested the chassis 2 on the track, I wasn't running a ball diff. But when I get off the throttle of chassis 1, it will carry way too much speed into the turn compare to chassis 2 which will slow down, is this due to the ball diff?
