I would encourage you to sit down with your team and figure out a list of objectives you would like your summer project to fulfill. Once you've done this I would encourage you to use the chiefdelphi search function to read up on butterfly drives from older threads. Once you understand your design objectives, have an idea of where a butterfly type drive falls on that, and seen a number of designs other teams have already made you can properly assess if you should try to design and build one or if your time would be better spent working on something else. When done properly off season projects can be an extremely valuable resource both in terms of populating your team's design shelf and teaching students.

Actually, right now it's just me looking at drive train ideas; other people have AP tests to study for right now and just a lot of schoolwork in general. I want to have a list of detailed CAD designs to show the team later once we start thinking about summer projects, so that we can make an educated decision about what we want to try.
I've been cadding only swerve drives and shifting gearboxes up to this point, but I was wondering what I should aim for in terms of weight and size if I CAD a butterfly later.
I want to stick with swerve personally, but the problem is that the programming is very difficult. With a butterfly drive, there is already a lot of programming released, not to mention the programming overall is easier.
