Armstrong Titanium Core Fuselage A+ The Armstrong Titanium Core A+ Fuselage is a significant step forward in foil fuselage design stronger, more compatible, and easier to set up than ever before. A solid titanium core runs through the heart of the fuselage, and full-width titanium barrel nuts lock the mast and front wing connections firmly in place across their full width for maximum strength and load distribution. The unique HEX fitting for both mast and front wing creates 360-degree surface contact, spreading load evenly and keeping everything tight and precise. The tail wing connects directly to the fuselage no TTF adapter needed making rear wing changes simple and shim-free for most riders. Those who want to fine-tune their setup can use the included Polycarbonate Pro Shims, which offer more than five angle settings in 0.5-degree increments from -1 to +1.5 degrees. These shims also allow full compatibility with Armstrong's Forward Geometry boards. Fully compatible with all existing Armstrong HS and CF wings, masts, and tail wings, and an upgrade kit is available to retrofit current front foils and masts to A+ System barrel nut fittings. The shorter TC50 is specifically designed for surfing and kiting, where tight, snappy turns are the priority.
