His planes are going to be collecting dust after few flights. I think he's building them to make video and make money. He didn't even test the torsion load of the wing.3.8g is usually plus a 50% safety factor. So ultimate load would be 5.7g. 3g is kinda skimpy compared to that. Dead calm weather only IMHO. And no aerobatics. I believe that his biplane had an even lower test load.
