Do the patents clarify what the end plates on the wings were intended for? My first guess was that they had control surfaces making use of the rotor wash, but I don't see any mechanisms.

In UK patent 432245, for an earlier design, they are described as 'stabilising surfaces' pivoting on a horizontal axes aligned longitudinally.

Based on recent research, Asboth managed well himself :)
An image from her book. The second is the original version, found after his death.

A photo of the AH-3 model:

from Index.hu article (https://index.hu/tudomany/2016/11/28/a_nagy_asboth-sejtes_feltalalo_vagy_kokler/  in Hungarian) which, is interestingly titled "Asboth, genius or cheat".
