Note: I had to delay the design update due to ongoing development of my printer and other projects. I'm eager to bring this design online with some exciting new features as soon as those developments are completed. Sorry for any inconvenience this may have caused. Update: Version two is on the horizon, packed with plenty of mechanical design changes tailored specifically for the Raspberry pi zero and camera. Update! The redesign of version 2 will take a bit longer than anticipated due to deeper design revisions aimed at enhancing rigidity and component integration. The primary objective behind this development was to gain hands-on experience in design and material strength, as well as to inject some fun into creating a compact FPV vehicle inspired by the recent 250 race class. While I didn't focus on achieving top-notch racing performance – given that a CFK plate build is inherently more rigid than PLA – my goal was to increase flight time for leisurely cruising or use as a base for scientific operations like mapping or inspection. As it turned out, the flight time came in at around 17 minutes with a standard FPV camera, which I considered a resounding success despite encountering issues during testing. I'm particularly fond of incorporating an „exoskeleton“ design, which is nothing revolutionary given its widespread use in aviation and DJI phantoms or Microdrones. The main benefits seemed to be a more streamlined appearance, improved aerodynamics, elimination of the need for CFK plates, complete in-home production (excluding electronics), greater freedom from suppliers regarding the frame, protection for sensitive internal components, and finally, enhanced design flexibility. Print Settings: Printer: Turnigy Fabrikator Rafts: No Supports: Doesn't Matter Resolution: 0.2 Infill: 20 - 50% Notes: To facilitate a smoother printing process, the frame needed to be kept relatively simple. Fortunately, my printer handled all shapes without excessive support material. The canopy can be printed entirely without supports. However, the arms in V2 are slightly more complex due to their hollow design and tendency to deform; nonetheless, they turned out well enough for the first complete prototype.
