So this is a photo of one of my team’s old drivetrains. All around it’s just a decent drivetrain design, but just posting a picture doesn’t really explain why you think this is a good idea to others, which is kind of the whole point of this thread. It’s also a good idea to credit other for their designs or put a link to the original post in your post. I based this drivetrain off of one of the gearings in this post by Xenon27.
