Lets see if i got it,
My understanding of a knife edge spin is that i pull into a vertical let it stall and just before the plane reaches the KE position i give full throttle, left rudder, down elevater, and some but not all left aileron.

I'll try the lower rate of aileron today and see what happens.

BTY is the low rate of aileron also better for inverted flat spins? i can do the inverted spin but it is not really flat like the upright i can do. i can get it flat coming out of a blender, but i am still inconsistant.

Thanks
