The Art Yarn Flyer was introduced in 2015. It has a huge 7/8ths inch orifice. It fits on the S10, S15, S17, S51, S70, S71, S75, S76, S77 wheels with "Irish Tension" (Bobbin-Lead tension). The Bulky Bobbin is recommended for use with this flyer.
Scotch Tension Louet wheels do not allow for use of the Art Yarn Flyer, with the exception of the Victoria when you purchase the Victoria Art Yarn Head. This converts the Victoria to Irish Tension/Bobbin Lead, which allows it to take the Art Yarn Flyer and Bulky Bobbins.
Here is a short video which shows the Art Yarn flyer:
