If you want a very quick fix for this, here's a solution that will work. I don't like just giving people "the answer" to problems like this but it doesn't seem like you guys really know how to do motor calculations and having a useless robot all season is a pretty harsh price to pay for that.

If you replace the CIMple Boxes with stock 12.75:1 Andymark Toughboxes or Toughbox Nanos - your drive ratio should be a lot better. You will still be right on the edge of controllability and current draw (12.5 FPS) and it might not be pretty but it will at least be able to move around.

You will also need to support the gearboxes with something more substantial than bolting them to the piece of wood. A good trick is to take those big pieces of hexagonal tube you got in the Kit of Parts and connect each of your gearboxes to the one opposite it. That way they will both hold each other rigid.

Keep in mind this is by no means an ideal solution - this is just the quickest way to do it with AndyMark parts you could order or have now.
