Foil Drive Fusion compatibility with F-ONE ROCKET SUP DOWNWIND PRO CARBON

I have a 7’ 10" 130 Litre with GoFoil Carbon Plate Mast V2 70cm

I am considering the Foil Drive Fusion with 3 blade prop. The Rocket DW has a step down that requires a battery shim adapter for the long Fusion battery.

Will I need the wired antenna to get connectivity on this carbon board?

Will the 72 inch wire be long enough to slide the mast/battery to the furthest position after looping to the deck? Currently my mast is mid point on the tracks.

What length bolts needed to go thru the mast/battery/2mm wire plate adapter?
