Rich, take that thing way up, then straight down with left ail spinning the heck out of it, then go full right rudder and full down elevator and while you see it starting to enter a inverted flat spin start going to right aileron and giving it some power at the same time(about half power to startand stop there) but keep going to right aileron till its flat, works every time with the proper adjustments, maybe a little one way or the other but you can do it
