Leading Edge Slats on the Me-109

should really come back to some qualities of the 109 here from this quote from the RAE report..

LOL, you very conveniently emphasize only the facts that fit your world without considering the final conclusion of the RAE.

Taildraggernut says:

The part in bold is describing a stall with the incipient stages of a spin,

Yes it does describe the conditions a spin should result in!!

Thank you for recognizing that!!
However your conclusion is not correct.

Taildraggernut says:
in this case the evidence shows that slats have absolutely failed in prevention of the condition

As evidenced by the RAE report:

RAE report says:

When the slots were fully open the aircraft could be turned quite steadily until very near the stall. If the stick was then pulled back a little more the aircraft suddenly shuddered, and either tended to come out of the turn or dropped its wing further, oscillating meanwhile in pitch and roll and rapidly losing height ; the aircraft immediately unstalled if the stick was eased forward. Even in a very tight turn the stall was quite gentle, with no tendency for the aircraft to suddenly flick over on to its back and spin.

Which is the normal effect of Handley Page automatic slats....
