Also whats with he beefy gussets, if your trying to support the upper frame of the drive base why not do something like this, it saves you more space as well as supports from all the post instead of just your 2 points.

Your point about #25 chain is a very valid one, #35 is overkill in most FRC drivetrain applications, and #25 is more than adequate in a well designed, aligned, and thought through power transmission system. That is why we are, in fact, using #25 chain.
The side rails and gussets were designed around our strengths. The picture you posted is one of 254's drivetrains, and while they have a fantastic design, we do not have access to the same resources that they do. They design around a welded aluminum frame, where as we depend largely upon gusset and Versaframe construction, due to a lack of machining resources.

This is a large part of those beefy gussets. Another part of the reason behind them, especially the strength, is that they will be the main support for the bumpers on the side of the bot. All the force from a hit on the side will go right to those.
We plan on the bumpers attaching with a latch of some sort at the point of the hex, and a section of C channel at the front and the back. The plan thus far is to have two piece bumpers, U shaped on each side of the robot.
Does anybody have any interesting, unconventional solutions to bumper mounting, or thoughts about our bumper situation?
