I enter mine sort of the same way, but instead of starting the dive, I let the plane stall,
or I'll cut the throttle, then I give full Rt. rudder, full down and full Rt. ail. and as she
rolls over I'll slowly input Lt. ail. till she stats the inverted flat spin.. adjusting throttle
and ail. input.... There are different ways to enter it... Then there's the F. S. landing...

I just started doing blenders which end in a inverted flap spin.. I think that's what they
are [sm=confused.gif]....
I go vertical till she stalls, do a hammer head / rudder turn and head stright down
and input full Rt. ail. let her spin for awhile adjusting throttle to increase spin, at your
choosing while holding full ail. give full Rt. rudder, the tail of the plane will move out
some and the spin will increase sort of violently, you can play with the throttle to
really shove the plane around... Then input full down elev. which will push the tail
outward incerasing the spin, then she will slow down into a inverted flat spin....
depending on your speed it put a lot of stress on the airframe... But it's Kewl
exit however you like, Or shoot for the F.S. landing to top it all off and call it a day
