My team is using a 4 wheel design (but that will be changing very soon
) with chain. It has a two speed transmission, similar to the one we used in last years FVC competition with a small change.
This is the test bot we made over the summer
Thats a little dated, but the transmission is no different.
Best of luck to all FTC teams!

Team Unlimited (FTC #1) and its members
