With the Flip this is an easy move. Best approaced inverted with height.(mode 2 I'm afraid) or approaching a knife edge. Just give it max up elevator and aileron, ie throw the stick into the top left or right corner with full power or keep blipping to full power. Then for fun throw in full rudder!!! With practice the plane can seem to stay in one spot. To recover neutral all controls. Watch it go mad with opposite aileron and rudder!! As always max throws.
