Is tensioning necessary for #35 chain?

[BrendanB]

We spaced our no. 35 chains during our design and the chains are still running on the robot although a little more stretched out after the brand new chain we used was stretched out.

I as little skeptical myself at first so we did have a backup chain tensioning system ready to use but the chains have been satisfactory.

Keep in mind that the longer your chains are the more links you have which is where the tiny bit of stretch is coming from. With the decreased frame perimeter sizes this is less of an issue compared to 2012 and before.

We are definitely going to try to use the same method in 2015. Our mechanical team loved not having to worry about chain tension this year for the first time.
