No, no, I haven't any experience with IPS. I do have experience with murphy's law, though: What can go wrong, will go wrong.
Hitting anything with a prop is bad.
The grounding part, was a halfassed joke, but I can't help but think, what will be done to protect the props? Weed, rope, a piece of wood, a grounding and so forth? Personally, I am very wary about things like this, because it introduces a source of problems in order to gain speed (and economi, as it were).
