Most of the SP140 is not very DIY friendly like the X4 but if you want to weld up your own frame I can send you the files to help. And stuff like the motor and ESC firmware is not open source even though it was designed for us. I don’t think APD would want to open source there firmware but you’re welcome to ask them. I have 3D models for the ESC and stuff like that. Our throttle controller stuff and firmware is though and thats what most would be wanting to experiment with.
But ya the Sp140 would much more of a pain to make DIY from the ground up IDK if you’d wana make it. But if you need the files for if you want to make a rig to mount it to a trike or something like that, thats no problem.
