Back that statement up. I'll wait.




What I'm getting at is that each setup is different. Blanket statements like that one should be double-checked. I could see that big of a drop for large wheels, sure. But there are a variety of factors that could play in, like size of pneumatic tires, number of wheels, presence or absence of non-pneumatic tires, inflation of tires both absolute (gauge pressure) and relative (different gauge pressures between different tires), and wheelbase vs trackwidth. Even desired "rock" can play in.

So for any given setup, that statement may or may not be correct. Stating that "X is the way to go" is not a particularly good idea--but stating that "for this particular setup [key details like wheel size and drivebase size], X worked well" will provide a really good starting point.

For reference... I don't think the team I was on in high school used that much drop on a 6" all pneumatic 6WD drop center. That being said, after the first event two of the pneumatic wheels were swapped out for AndyMark 6" non-pneumatics due to bouncing that made controlling the robot "interesting". [edit--forgot earlier] As I recall, we were a 37" long 27" wide robot (this was before frame perimeter, and you had to fit in the box to compete--no bolt heads sticking out).
