FLIPY FLAPS!
I think I would simply observe that the notion that one need be a "certified test pilot" in order to safely roll an aircraft is preposterous. WW1 pilots flew things held together by baling wire and chewing gum which had the aerodynamic characteristics of a paper mache snake while getting shot at and rolling RATHER A LOT, and even a lot of them managed not to crash, in spite of the fact that they were not CERTIFIED TEST PILOTS.
Now that's obviously leaving aside the question of how wise it is to advertise such things.
This is the right answer to this catastrophe of a thread
