FFF The first time I spun a 150 (non Aerobat) was during my PPL as I was terrified of the prospect of spins so asked the examiner to demonstrate. After the ashmatic little Cessna had staggered to 6,000' (We need lots of height, I don't trust this thing. Gee thanks.) the spin was demo'd. Wheee thinks I, lets have a go at that.
Stick back, bootful of left rudder and open throttle wide. Damn that thing went around fast
I've never seen an instructor move as fast as that chappie did when he pulled the throttle closed.
So, I don't know about flattening the spin but an open throttle makes them turn really fast but the wings do stay on.
