I would recommend switching to arcade drive for a number of reasons.
- If your drivers play first person video games, they are most likely used to controlling themselves in the same in the same way that split arcade drive works (where you put rotate on 1 stick and back/forward on the other).
- Arcade drive allows you to control your rotate speed independent of your forward speed. This can be used to do some slick maneuvers.
- Tank Drive (unless you do some programming magic) often results in it being difficult to drive straight (as both sides won't be at exactly the same speed).
- Tank Drive is not intuitive to new drivers from what I've seen at the demos we've done.
If you're interested in more advanced stuff, check out 254's cheesy drive [
