Indestructible partially flexible quadcopter
cults3d
I present to the thingiverse community my durable quadcopter design! (ok, indestructible could be too much, time will tell...). Since I recently built and crashed 2 quadcopters (not a very good pilot I guess...), I saw that both of them broke in the body-motorbeam joint. So I decided to design a frame that could withstand an accident. My requisites were: - Small quadcopter, this one is ~285 diameter - It should fit all the electronics I wanted, so it should be quite versatile - Able to survive if I crash it It finally ended with this design. It is meant to be printed with flexible filament and normal filament. Almost every parts joints are made with hard and flexible filament, to absorb hits and vibrations. Green parts (the parts labeled with "_FF") were designed to be printed with flexible filament, I used Filaflex 82a, and blue parts are PLA (probably ABS or PETG would be better). Filaflex filament is very very hard to break, so it should absorb the impacts without breaking. The beams are made with cheap ebay carbon fiber tubes, 14-12mm. I have used four 250mm tubes, cutting two of them to 17,8cm. Also, it is necessary to drill them in order to fit the screws. The electronics I have used are: - 4 12A esc from hobbyking - 4 2400kv turnigy motors from hobbyking (discontinued...) with 5030props - Runcam split 2s and Eachine TX805 5.8G video emmiter - Pixhawk controller and M8N GPS - 1300mAh 3S lipo - holybro telemetry module - turnigy 9x radio (with ppm encoder) To mount it, I recommend to fit all the electronics in both platforms and screw them with the beam to platform pieces. After that, mount the tubes and tube joints, the motors, finally place (if wanted) the protectors. My configuration is ~750g, and it gets between 7 and 10 minutes flying. It could probably improved, many pieces are optional, (legs, protectors, ...) and I may have used too much electronics. Enjoy!
