In the mid 70's there was a british single skin hang glider called the Vortex which had a line of holes along the 1/4 chord line towards the tips supposedly to prevent tipstall. Dont know if it worked.

I suppose a slat or slot could be considered as a continuous hole , these work for full size aircraft to delay separation, does anyone know if they are effective at model Re numbers?
