So I finally got up on my foil assist. Swapping out the motor was the missing link! I can fully efoil the assist although the battery felt like it could have cooked an egg after about 5 minutes.
I’ve got full logs so can post them once I pull them off the ESC.
Here’s the full specs of my system:
Rider weight 95kg
Slingshot wf1 24.5L board
10S4P Samsung 30Q battery
Freely arc200 ESC
Apex 6384 170kv motor (pretty sure the 140kv would be fine too)
Gong veloce XL wing.
