Foldable QuadCopter (with UDI Parts)

thingiverse

Foldable Quadrocopter I cannibalized an UDI-818A and used the rotor-arms and the circuitboard for this project. There are some other copters available on the market using nearly the same parts but have different labels/names. Here it is just necessary that the arms have a 4x4 mm profile. I made a bracket for the arms that is able to engage in different positions. So you can change the behavior of the copter in some ways ... that's fun. The brackets are very tight to the case so maybe they need to be sanded a little bit at the tip. To assamble the housing I used some little screws (2.5mm??) as they come with mainboards and other computer stuff. They easily cut threads themself. The assembled copter is a bit heavier than the original but is stable in flight and lets you make really agressive and fast maneuvers. You can save battery if you do not connect the LEDs to the board. Overall printing time on an Up! mini at .2mm layerhight and in fine-mode was about 4 hours. I'd recommend to print the brackets very dense. No support material needed. Hope you like it and if you print this thing please upload a photo.
