I know we're not the only team that can't have both.

Just wondering, what do you consider "light?"
This year our entire drive train (chassis+wheels+transmissions+motors+chain) ended up at just over 30 pounds, and we didn't do anything special such as 7075 aluminum axles/gears or any machining for lightning holes. We even had a couple of solid aluminum blocks for modularity purposes, so if we had welded it, we could have dropped the weight about 3-4 pounds.
We usually aim for under 45 pounds drive train + electronics board, maybe a bit more if we have pneumatics.
