The source is made by Mike-vom-Mars. There you will find a wirering-diagram as well, which I found very helpful.
His design is great, but doesn´t protect the cam enough. So I made a new mount.
After printing the first version in PETG and breaking it on one of the first flights, I made the next design a bit more sturdy and printed it in ABS.
Print it with 0.1 layers and 100% infill and support.
I added a dust cover for the front, that gives additional stability.
With the new cam you get a lot more contrast and it´s easier to see where you are going.
