My opinion:
From the photos on the website I was unable to see where the axles will be able to have any articulation.
It doesn't look like it can do any offroading at all. I think if he took a corner with any speed the body would roll over onto the tire and stop that wheel from turning.
Needs way more lift to handle those tires and be able to do any off roading. Engine is too weak.
