Dw Armstrong board w Gofoil hydrofoil

Has anyone seen an Armstrong downwind board with Gofoil Hydro Foil and mast???
I had a problem using Gofoil two years ago on an Armstrong Ford but it wasn’t a brand new downwind board.

Works great for me (winging the 7’2) with Gong and Gofoil, mast towards the back.

I’m using the 6’3” right now with the V2 mast. I have it in the front 4 holes on the mast, as far back as it gets. It works good! I’ve used RS1150, RS850, and GT 1770 with it.

That looks good
