Besides, #25 chain is more than strong enough, provided it's done correctly! Here's what I mean by correctly, so I'll have a post to link people to every time this nonsense comes up: It needs to have the sprockets perfectly co-planar. The chain needs to be properly tensioned (not too tight, not too loose). That's ALL! I've used #25 for 4 years now and NEVER had a failure, and that's for both arms AND drivetrains!
Another point: We all have NO idea what the Kitbot is going to be, NONE of us do! It hasn't been built yet, so we don't know what kind of chains, if any, will be on it. Let's please save from making generalizations about a system that hasn't been delivered yet.
I apologize for the outburst, but I HATE the myth that #25 is "too weak" or "too hard" for FIRST use. So please, OP, whatever you build, save yourself the 5ish pounds, and use #25!

Well, let's not discourage innovation; rookies should go for no less than a full swerve drive.
It's a fact, #25 is weaker and less forgiving in tolerances than #35; not attacking #25, It's just fact. A lot of teams have the experience, resources and ability to work with #25, but, not many rookies do.
I have seen plenty of issues with rookie/newer team's drivetrains with #35 chain. I support what Peter said; let a team get a decent drive going in all other aspects before they start trying out #25.
