I don’t know if Nopel is here, I’m guessing not since I haven’t seen a post yet. The M1337 is out of beta today and can be downloaded from his Odysee.

I read through the manual, he did a great job explaining every little detail and he included a ton of pictures. I’m hoping I can build one some time next year.
