Here are some pictures of my Karlsruhe's laser cut and etched superstructure (my design) there are some small bits that need adding still.





And here is my personal favorite. my cnc gearbox designed and cnc'd by me.

rough dimensions 2.5 inches by 0.8 inches with a rounded part to fit into the inside of the hull. (not including motor). the motor is a 100W brushless motor. next on the agenda is an aluminum sealed box for the mamba reversing brushless ESC. Probably followed by a box for a 3 series lithium polymer battery pack. (or I might cheap out and just go for the round cells)
