Agree on the rig extension as you suggest but then that adds to the weight**. As for grass landings, fine but since this vehicle is being marketed as road worthy, I doubt they’d want to limit its marketabilty. I think both of us have seen major flaws here. Surely, they would have considered this...I hope.
**Might have to consider an extension or lift system a la the old French Citroen cars that used air to lift the car. Again, weight becomes an issue.
