1. If you are using 4 DC motors, but all for drive, then I would suggest putting two motors in one output, it works really well. If you need more info, let me/us know.
2. Also, if you are that desperate, try asking another team for a motor controller? Offer to pay for the controller, the included wires, and shipping. I'm sure in this community, there are teams who are more than willing to hand over something they're done using. Just add a new thread and I'm sure SOMEONE can offer you one.
