It probably took a lot more torque to get those wheels rolling than lighter ones like the VexPRO traction wheels (6" in 2013, 4" in 2014) that we've used.
One of the first things that comes to mind when you wonder about the physics of accelerating a robot is inertia, but rotational inertia can become a big factor too in some designs. That's my best guess as to what it was, especially if you didn't have as much of a problem with it in other years.

Hmm, yes, they were 8 inches Colsons, so pretty heavy. We were planning to use 6 inch wheels but then some complications arose that caused us to use bigger wheels, We didn't think it would have that adverse of an effect on the drive performance.
Could electronics be an issue? Or is that a minor concern, efficient wiring?
Thanks for the help!
