What is the right drive train for this game? (From a drivers point of view)
why does this gearbox better then other gearboxes?

Using the stock gearboxes and about a 2:1 ratio after that I found that our robot had a lot of torque and traction coupled w/ 6 wheel drive. It was pretty fast as well but didn't turn very well. This drive train proved great for defense and our bot kept the opponents to less than 25 points when playing pure defense. At Florida we were ranked 38 or so and kept the #2 team to one, ONE tetra scored.

Stock gearboxes that were provided by FIRST do the job just well...I personally don't see a need for a 2 speed gearbox, or a need for a bully robot...because if you want to win this game you need to be capable of scoring.

I was quite disappointed with how the game played out. Any sort of drivetrain whatsoever (even just 2 CIMS) would have been just fine. At least in qualifying rounds nobody even came close to touching anybody. There was no contact whatsoever. You would think that on the same size field but 50% more teams than last year there would be some CONTACT but there was none. At the start of the build, we thought opponents would even double-team us but boy were we wrong. We thought that since everyone had essentially been "given" a good relaiable four motor drive, that we needed something way above and beyond. unfortumnately, this was not the case. Opponents just ran away. No one engaged in any sort of pushing whatsoever. It is all the fault of the first week of regionals scaring the ____ out of drivers making them believe they were going to be penalized for any exciting action. We put hours upon hours into our HexaMax 6 motor (http://www.chiefdelphi.com/forums/showthread.php?t=35266&highlight=hexamax) with 2 speed (http://www.chiefdelphi.com/forums/showthread.php?t=35272&highlight=hexamax) drive system when it turned out that anything that moved was useful enough. 3vs3 on a pretty small field but no one banging into each other is not exciting for me.

Our drivetrain turned out to be nothing like we expected. We had initally aimed for a steady and strong robot, capable of capping and playing defenses but we eneded up getting too much friction, which makes turning really hard as our robot bounces when we take sharp turns. However we are pretty hard to push around. I believe that a robot that goes around 10 feet/sec takes smooth turns and is hard to tip would be a typically perform well in this year's game.
