Sorry, there is nothing out there that meets your criteria. It is almost unrealistic.

Unless you are lightly driving around in a circle, 2hrs of bashing is some serious abuse. You'll likely be wrenching on something within those 2hrs if you are bashing. You couldn't even run 2hrs without having to change the receiver battery (even 2300mah LiPo packs can't run that long). Two hours of runtime is more than half a gallon of fuel. Nitro engines, especially any RTR engine that is seriously bashed, would be hard pressed to run beyond several gallons. If you are running on salty beaches, mud, etc, you will be rebuilding your car after almost every run. You can waterproof the electronics, but the bearings won't last more than a couple runs... especially once they get foreign debris in them and you shelf it. You will probably have to do more than 30 minutes of wrenching regardless of the car.
You will probably be a little better off with a 1/5th scale gas, but I don't have any insight/experience for you there.
