OpenRC 220 FPV Mini Quadcopter is the second quadcopter to join the OpenRC product family. It´s a modular design with “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%.
