I think
thailazer described the function of these "baffles" very well in post #10 above:..."
creating a vortex to help keep the airflow attached to the wing allowing a lower stall speed." Sure thing, the effect of these "baffles" on the Hots exceeded my wildest expectations so I will certainly keep them despite the "added weight and complexity". My Hots is currently a "test bed" for evaluating these "baffles" intended to be used later on the main wing of my next canard project.
If you look at post #7 in below thread you will see my efforts to avoid the dreaded main wing "superstall" frequently experienced on canards:
