Quadrocopter 44cm diameter

thingiverse

I built this because my old Quad (aluminum frame) couldn't withstand a rough landing on the beach as new tricks were added and I needed a project to get back into 3D printing. It was also a great opportunity because we can. My old setup was too damaged from crashing into the snow in my room for extensive testing. However, after a brief hover test indoors, the model performed remarkably well and showed excellent stability. Instructions are provided below. This drone prints quite easily and remains stable enough even during takeoff. I tested various infill patterns for the arms, but it seems that not all of them have a significant impact on its performance. Upon closer inspection, I think the honeycomb fill might be the most effective choice for this design. For propellers, I'm using 8x4-inch ones and they work great with the motors. Here are my specifications: * KD A20-26M motors with 15A current draw and 1130KV rating * MultiWii firmware running on a Flyduino NanoWii controller board * ESC model: unknown (will have to double-check later) * Power system consists of a 3S 2200mAh, 25C Turnigy accumulator battery pack. For anyone who wants to make changes or modify this drone for their own purposes, I've attached the original .blend file. Feel free to use it as is and don't hesitate to reach out if you need further assistance with modifications or anything else.
