3 inch Whoop/Quadcopter for 16x16mm stack

thingiverse

This is my attempt to create a quadcopter frame that I could use to learn in both the design of drones and flying and configuring these things. A design constraint for me was to use the parts that I bought to eventually build&fly the miniQbit quadcopter tailsitter plane: https://www.miniqbit.com/ The new nosecone is larger to support a camera mount and VTX and a platform for a GPS in the back, as well as a mounting plate for a Runcam 5 with this enclosure: https://www.thingiverse.com/thing:3729962 The plate broke off after the first crash though, so another edit is incoming here eventually. The essential hardware I use is: motors iFlight XING2 1404 4600KV Toothpick Motor Receiver: FrSky XM+ Micro D16 SBUS Full Range Mini RC Receiver Up to 16CH FC & BEC stack HGLRC FD413 16x16 Stack F4 13A 4in1 Lipo: ZOP Power 11.1V 850mAh 100C 3S Lipo Battery XT30 Plug Props: 3x3x3 by HQ Durable I print the model in ABS because it is lighter and more crash resistant than PLA, and because my printer can handle it (enclosed). I use 0.6 mm wall thickness on the 0.4 mm nozzle for better layer adhesion two wall layers and a relatively low 25% gyroid infill. Circular/Concentric supports work really well on this model. I print it with the upside of the drone flat on the build plate. This is my third iteration on this design and there might come more as I keep learning, so I might update this thread, especially if I notice any interest in it. Cheers & have fun! Changes V3 to V3.1: - Mount area for receiver on the back. - Slits to guide Motor cables - Slightly thinner motor mount plates (now 5 mm) to fit my 7 mm mount screws - Strengthened and broadened battery mount. List of planned improvements for V4: - Dedicated holder for my Betaflight M02 VTX (it is currently glued to the inside of the nose cone) with room to reach the pit mode button - More air holes for better cooling - Improve Runcam mount to be more rugged - Possibly add some kind of feet or landing gear to protect the battery when bouncing on the ground or crashing - Improve cable management (currently its all zip ties) - Modify whoop shape to increase coanda lift effect - slightly reduced motor mount plate thickness
