30+ MPH Robot Possible?

Yes. But go big or go home. Forget this FRC parts business. Do it right.

This is awesome !!! But unfortunately it looks like it costs $$$$$$.

This seems like a problem that is easily solved by shopping around the RC car hobby sites until you find one that fits your budget. They've already put decades into research and production for fast remote controlled vehicles that handle well. They probably cost quite a bit less than sourcing individual parts yourself, too!

I'd suggest researching diy electric skateboards. Check out http://www.electric-skateboard.builders

I'm building one now and it should go roughly 20mph but there are a lot of people on there that are going 30-40mph and weigh anywhere between 150-210lbs. That forum is really helpful and talks about electronics, mechanics, etc. It may be overkill for the weight but you could go in that direction and tone things down a ton. If you search the forum there are calculators to figure out speeds based on your batteries, motors, weight, current and gear ratios.
