Foldable QuadCopter (with UDI Parts)

thingiverse

Foldable Quadrocopter I upcycled an UDI-818A and utilized its rotor arms and circuit board for this project. Several copters on the market share similar components, distinguished only by varying labels. This foldable design hinges on the 4x4 mm profile of its rotor arms. To customize flight dynamics, I designed a bracket that adjusts to different positions, enabling diverse behavioral options. The close proximity of the brackets to the housing requires slight sanding at the edges for secure fitting. Assembly relied on miniature screws (2.5mm) commonly found in mainboards and computer peripherals, which effortlessly create threads without damage. While heavier than the original UDI-818A, this copter achieves remarkable stability during flight and permits swift, aggressive maneuvers when LEDs are disconnected to conserve battery life. Total printing time, conducted at a 0.2mm layer height with an Up! mini printer, totaled approximately four hours. It is advisable to print brackets densely for added durability; no support material is required. I would appreciate it if you share your results and consider uploading photos of your assembled Quadrocopter for sharing purposes.
