Best way to build a budget crawler that will not break is to purchase items that are known to work allready.

Trust me I've tried several ways to come up with something on a budget that works well. And the costs are way to much.

You can spend $50 on gears for a tranny that you are trying to make from scratch. Trust me I've ventured every avenue.


BUT that doesn't mean you can't or shouldn't try. There are many things out there that may or could work if found, tested and proven to.
