It’s time to start work on the fuel tank! Finally..

Made a mock-up out of cardboard to get a rough shape and made sure we can maximize all the space available. Cardboard is an easy way to prototype rough shapes. Not very reliable however to get exact measurements for a complex shape like this.

After that I fabricated another more refined version from plastic hobby-board to validate the final design, all while drawning it in CAD to validate and log all the measurements. So much shapes and triangles this thing makes my head hurt.. 35 pieces in total!

Need to maximize all the space I have to get the tank as big as possible. Hopefully minimum 9 liters, and yes that’s already very small 😂..

Onwards to fabricating everything out of 2mm thin wall aluminium.
