Meet the CarolinaXC XClass Quadcopter Frame. This frame give you the option to set it up however you want. It doesn't rely on any specific mounting hardware or arms. This is a very good way to get into XClass and experiment a little until you find what works best, and it all starts with some carbon fiber plates.

The kit comes with 3MM top and bottom plates and 4 3MM pairs of motor mounting plates; all the carbon is 3K Twill Weave with a Matte Finish. From there you do whatever you want! The arms can be sourced from any carbon fiber manufacturer in any shape as long it fits in between the stand offs that are spaced 29MM apart. The stand offs needed for the frame are 35MM in height for M3 screws. The arms are held in place by 3D printed TPU mounts that can be adjusted to fit any shape. RDQ will have the prints in stock soon but the STL files can be downloaded here.

If you are sourcing your own arms you can cut them to the following length in order to make the quad the following sizes.

  • 500mm - Approx 1050mm
  • 475mm - Approx 1000mm
  • 450mm - Approx 950mm
  • 425mm - Approx 900mm
  • 400mm - Approx 850mm
  • 375mm - Approx 825mm

 *RDQ will soon stock a variety of arms for the Carolina XC Frame*
