Armstrong A+ System TC Fuselage

The Armstrong A+ System TC Fuselage is the titanium-core fuselage component in Armstrong's A+ foil system, connecting front wing, mast, and stabilizer into a single rigid assembly. Introduced as part of Armstrong's A+ System upgrade, the TC (Titanium Core) fuselage uses a solid titanium rod running the full length of the unit, encased in a 5mm solid-wall carbon fiber tube. This hybrid construction is engineered to maximize stiffness and durability while keeping weight low. The front wing attaches via a hexagonal interface that seats snugly before hardware is tightened, and full-width 8mm titanium barrel nuts with 28mm through-bolts lock both the mast and front wing connections. The tail wing mounts directly to a cutaway section at the rear, eliminating the separate tail fitting piece used in earlier Armstrong systems.

• Construction: Solid titanium rod core wrapped in 5mm solid-wall carbon fiber tube
• Hardware: Full-width 8mm titanium barrel nuts with 28mm through-bolts
• Available sizes: 50cm (19.5"), 60cm (23.5"), 70cm (27.5")
• Weight (TC50): 340 g
• Weight (TC60): 407 g
• Weight (TC70): 475 g
• Tail shim system: Polycarbonate Pro Shims with 0.5-degree increments (5+ angle settings)
• Compatibility: All Armstrong HS, CF, and MA series front wings and tail wings

The TC Fuselage suits riders across a wide skill range, from progressing intermediates to advanced foilers, depending on the length chosen. The 70cm is Armstrong's most popular option for all-round use — its longer span provides greater pitch stability and a more powerful pumping stroke, making it a strong choice for wing foiling, prone foiling, and downwind runs where glide efficiency matters. The 60cm targets experienced riders seeking a balance of maneuverability and stability, responding faster in carving turns without sacrificing too much composure. The 50cm suits advanced riders prioritizing tight, snappy direction changes in surf or wave-oriented riding, where reduced stability is an acceptable trade-off for responsiveness.

Because the tail wing attaches shimless at a neutral zero-degree angle by default, riders who want a simple plug-and-ride setup can leave it stock. Those chasing fine-tuned tail angle adjustments can add the optional polycarbonate Pro Shims for half-degree increments of customization.

The TC Fuselage sits at the core of Armstrong's current A+ System platform and replaced the earlier separate-tail-fitting fuselage design. It is compatible with Armstrong's full range of current front wings — including the HS (high speed), CF (compact freeride), and MA (mid aspect) lines — making it a versatile hub piece rather than a discipline-specific part. Within the A+ ecosystem, the fuselage pairs with Armstrong's Reactive Flex Mast and any current-generation stabilizer.

For riders comparing across brands, the TC Fuselage competes with similar titanium-reinforced or carbon fuselages from Axis and Unifoil in the same price bracket. Its distinguishing feature is the hex-socket front wing interface and barrel-nut through-bolt system, which Armstrong designed to reduce play and extend connection life over repeated assembly cycles. Riders already invested in the Armstrong ecosystem will find backward compatibility with older HS and CF wings, while the system is also forward-compatible with new wing releases.
