Yellowjacket Quad

A High-Performance Quad Design Inspired by Elite Racing Quads.\nThe design is incredibly versatile, with modular components that can be assembled in multiple configurations. When mounted mid-deck, as shown, it offers an ideal COB for racing and sufficient space for a battery beneath the quad, along with a camera mounted mid-deck.\nTo further customize your experience, consider mounting the arms on top of the deck, creating a secure space below for a small gimbal. This design not only allows larger propellers to be used but also helps prevent props from hitting the standoffs during assembly. \nAll components are 3D printed with high precision: 0.4mm nozzle and 0.32mm layer height at 3 perimeters with 50% infill, creating a solid base. The skids are intentionally kept lightweight to allow for better damage absorption during impact.\nFor the frame assembly, 35mm M3 bolts provide maximum structural support while standoffs keep all components organized. A pair of short 10mm bolts secure the top deck.\nIn addition, flying enthusiasts are recommended to utilize SunnySky motors - model X2204-2300KV Brushless on a 3s with Afro ESC's. As the designer recommends: feel free to personalize your build using favorite flight control units!!\nFurther Technical Notes: The first models posed several structural issues.\nThe initial decks consisted of simply flat extrusions made from a 2D drawing; when printing lineaire infill, this would cause them to twist due to misaligned axes and subsequent vibrating when loaded. Reverting back to fundamental design principles, new iterations featured 3D shapes combined with infill at +45 and -45 degrees to replicate the tensile properties found in composite materials. Furthermore, added features include longitudinal reinforcement elements.\nBy making sure three perimeters are sliced, it ensures an even distribution of forces across all struts.\nThe same challenges arose when building arms due to size limitations and insufficient structural support for heavy flight control components. Enhancements made to current designs involve running higher infill levels (up to 55% linear with layer offsetting for axis optimization), reinforced geometry incorporating biaxial stress compensation features.\nRecent experiments have shown promising results flying SunnySky motors on HQ propellers but may require adjustments depending upon intended power output or voltage requirements; some users successfully implement longitudinal rod installations.
