Re: pic: Offseason Drive Idea

It is a good start. Here are a few questions though:
Why not get rid of the unnecessary metal on the inner gearbox plates? Leave some meat around the upper bearing and the get rid of the rest.

Why did you place the pulleys on the outside of the wheels? For turning, stability, and other purposes it would be better to get the wheels out the extra ~1" on both sides.

Is your center pulley wide enough to fit 2 belts side-by-side? All the pulleys appear to be the same size.

CG does seem high, but depending on the game this may not matter. If you need essentially no ground clearance (this year), you can have your battery sit about a 1/2" off the ground. [Legally] Max your bumpers out to 20lbs and place them as low as legally allowed.

How are you bolting the chassis and it's components without collapsing the tube? It is not typically a problem with 1/8" walls, but every now and again you will have someone not paying attention and keep cranking on the bolt because they can still turn it.
