Looking for a backyard tank, something to run around my backyard. My 1/16th scale tanks get hung up in the grass and roots, so am looking for something with more clearance. It does not have to be a real tank, just something to run around the backyard and have fun, do not need battle ready.

So here is what I am looking for:
Larger than 1/16th scale with ~2" ground clearance.
Robust track system since I will be bouncing over things
Does not matter f it is brushed or brushless
Preferably a metal chassis and metal tracks, but not a deal breaker

Also what controller/ESC do you recommend for a tracked vehicle.
Thinking about something like this... but feel you guys will know about these things...
rc chassis
