Hi all. Recently in an airshow a pilot of Fiesler storch showed me the effect of full flaps on the ailerons of a Storch. At Full flaps the ailerons go both a few degrees down. The purpose is to increase ailerons effectiveness at low speed. The he said me the 109 has the same feature. I've searched a bit and i found these on the "Flying heritage" facebook page. https://www.facebook.com/flyingheritagecollection/photos/a.10152016899248666.1073741833.13883518665/10152095603113666/?type=3&theater And on this video of the Messerschmitt foundation you can see @ 8min10 the plane wit flaps fully extended.
