Our team seems to be a contradiction to this... We had many people ask about how we did our swivel drive, or crab drive. I remember at the Sacramento regional the team captain put me in charge of "bragging about the swivel drive" because he was tired of saying the same thing over and over. The answer to why not many teams were asked in depth questions about their drive trains in most likely due to the fact that there were mainly tank drive systems this year. I'd be willing to bet that the teams with strange and innovational drive systems/arms got many people asking questions. wow.... just for the record, that was the longest post of my life.
