Flew into Garden Valley last week and saw a Sportsman and a 185 with these on the wings. Tried to google it but, I wasn't sure what I was googling.
I found this picture on the Glasair website that shows them pretty good. Just curious as to what they are and what their function is.

Those are part of the BLR VG kit, at least on the 185. They have those deltas instead of VGs on the horizontal stab.

Those are a form of vortex generator that excite the airflow under the horizontal stab. Similar effect as mounting VGs on the bottom of the stab like some VG kits do.

Edit: Skinner beat me to it.
