supporting more motors

[fasteddys]

Hello this is awesome, I am new and love that you created this. I have two projects an RC car and elec lawn mower.

1. How can I add support for a couple more motors 4 or 5 motors
2. Is it possible to drive both the front wheels at the same speed/sync/differential turn left/right
3. What changes should I make to support higher speed/power motors

thanks
