OpenRC 220 FPV Mini Quad
IMPORTANT NOTICE: There will be a while before i get another set of electronics so that i can do a "build with me" series fo...r this one, sorry. So if you are not familiar with FPV, Quads and working with electronics maybe it´s best to wait. There´s also some programming needed of radio and flightcontroller.
If you still can´t wait i highly suggest you check out the resources about FPV below before even thinking about starting this project.
OpenRC 220 FPV Mini Quadcopter is the second quadcopter to join the OpenRC product family. It´s a modular, "self-supporting" design meaning that the design is as strongest when put together with all the other parts. This is a 220mm size using 5" props and the idea is to print all parts in a somewhat flexible material to allow for better impact resistance in a way that a material like Nylon for example will allow some "give" and thus better absorb a hard impact from a crash. The parts alone will feel "to flexible" but once they are in place and properly secured with screws it´s rigid enough. Even something like PCTPE may be suitable, haven´t tried it yet.
While testing i have found that a Co-Polyester like colorFabb HT based on Color Amphora HT5300 or Nylon filaments are the best suited for this design. A CF blend like colorFabb XT-CF20 och NylonX by Matterhackers will reduce the weight by approximately 20%.
