The frame is durable and weight-competitive (125 to 150 grams depending on materials/configuration).  Join Facebook group " 3d Printing - Home Grown Drones " for some flight test video on a 6s lipo: https://www.facebook.com/group... In keeping with the TBS Source One open source spirit, I am allowing full access to the native Fusion 360 files .  Commercial use and derivatives are allowed (and encouraged). Fusion 360 Files : https://a360.co/3j54ZgE Some experience with both 3d printing and FPV multirotor building is assumed.  Check out Facebook Group, " 3d Printing - Home Grown Drones " for advice and discussion.  YouTube " Drone Camps RC " for some good general mini-quad build guides.  You will become better at both  3d printing and drone building with this project. A simple list of hardware/tools/materials and set of instructions can be found below.  I'm flying Hatchbox ABS  for the frame, and SainSmart TPU for the cam, antenna, and motor mounts.  This material combo is highly recommended. The cam mounts, antenna mount, and rear vents are optional.  These work for my system, but there are many TBS Source One versions of these types of components on Thingiverse, Pinshape, etc. A list of hardware needed, tools, and instructions can be found in a .txt file called, "Birdbone Source Fork Instructions v1.txt" along with the .stl files. Enjoy!
