The support above and below is very good. That is one of the major shorcomings of our crab design last year. The grearboxes were too tall, so they could ben too much. That ended up putting more stress than was good on the upper connection of the gearbox. Your design eliminates that tilting ability of the grearbox. If we did crab again it would be vary similar to this. (Right now we will just go back to making a robot that actually drives!
