Hi Guys
The first component of the CardCat Class X200 Stealth Drone is complete. This is the Longitudinal CL (for Centre Line). It runs along the centre line of the boat. The longitudinal (which I will call LCL from now on as I am lazy) is composed of a piece of 0.65mm cardboard with reinforcing bars running along all edges, also in 0.65mm cardboard. These bars are glued to the LCL by 3mm x 3mm x 0.65mm "angle brackets" of 30mm length. The structure is kind of an "I Beam" in cross-section. Calculated weight 8.77 g and extremely strong and stiff for its size and weight.
