Carolina XC (X Class) Frame features
You can purchase the complete frame or just the parts you want.
Pick and choose the items you want. If you have a 3D printer and want to print your own TPU Arm Clamps you can get the STL files here. You can also get the CAD file for the Frame here if you would like to make changes to it.
Available Items -
Carbon Fiber Plates (Default purchase) - Includes Top (1), Bottom (1) and Top and Bottom Motor Mount (8) plates. All Carbon Fiber Plates are made from High Quality 2.5mm, 3mm or 4mm (depending on version ordered) Carbon Fiber (3K Twill Weave, Matte Finish). All plates are chamfered on 1 side.
Arms (Qty 4 or 6) - Arms are 21.5mm X 19.5mm X 500mm Carbon Fiber Tubes. You can decide to source your own arms. The standoffs are spaced 29mm apart center to center so anything that will fit between the standoffs can work. For example 20mm X 20mm Square CF Tubes will work or 20mm x 30mm Octagon tubes will work also. The default 3D print files can be downloaded free here. You Can edit them to fit any type of arms you want.
35mm Standoffs (Qty 36) - You can source your own or choose from 7 different colors of 35mm X 5mm Anodized Aluminum Standoffs.
12mm M3 Stainless Screws (Qty 72) - You can source your own or choose from Black or Silver
3D Printed Arm Clamps (Qty 16) - These are designed for 21.5mm OD Round Carbon Fiber Tubes. You can also download the STL and STEP files here to Either Print or edit the design for different arms. Only the 21.5mm Tube clamps have been tested. As the other arm designs have been tested they will be offered for sale here at Great 3D.
If you are sourcing your own arms you can cut them to the following length in order to make the quad the following sizes.
If you want to mount a Session Mount on the frame I have added holes that match the hole pattern on this MRM Reaper Mount by Brent Collier and it can be ordered here.
If you need additional 21.5mm Carbon Fiber Tubes you can order them here.
If you have questions about the frame please contact us here.
NOTE that your order can take 2-4 business days to ship depending on our current stock of cut frames. Also ordering 3D parts can add 2-3 business days to your order.
If you are in Europe you can purchase the frame from our UK Based Partner GAATECH Carbon Design CNC and the 3D Printed Parts from MultiRotorSpares. (Links will be added soon).

I had almost given up Looking for an xclass frame that fit my needs when I randomly stumbled upon this website through a DuckDuckGo search. I realized later that I would have had an easier time finding my way here had I just looked at frame options on the xclass racing site.
I want to thank plastic spider and great3d for making this frame available. I ordered the 3mm thick version and am super happy with the quality I received. I still have yet to fly it but the build went really well. Great product!

I purchased the overall frame kit with 3D printed parts. CF and Printed Parts top notch. Only one thing that didn't work out for me was the holes for the Sma Mount didn't line up with the inner body clamps. Looks like that part was printed one size too big?. Also, had to lightly file/radius the motor mount holes, was ever so slightly binding on the CF - easy fix.
Planning on ordering another frame kit for another X Class build :)

I purchased the XC with everything but 3D parts. Carbon fiber machining is as good as anything I've seen ( I fly several Armattan frames). All holes are clean and edges are chamfered. I printed the 3D parts and assembled, I'm using the 21.5mm arms. With the arms squeezed in the TPU clamps I'm not able to slip or rotate the arm, solid. The motor plates were not drilled for the motors I use so Robert made new plates to fit my build. I've been on hold waiting for ESCs that got lost in the mail and had to be reordered.
If your reading this you already know how awesome the frame looks. Really hoping it holds up to the XC abuse. Joey
