What is the difference between FCS II, Fusion and X2?

They are distinct FCS systems with different plugs, fin interfaces and installation tooling. Do not substitute a part based only on the FCS name.

Which FCS II plug angle do I need?

Use the board's fin plan. The current plug guidance lists 9 degree for common thruster sides or front twin and quad positions, 5 or 3 degree for quad rears, and 0 degree for centre or stabiliser positions.

Can FCS Fusion plugs be used in epoxy and polyester boards?

Selected Fusion plug descriptions list compatibility with EPS and epoxy as well as PU and polyester construction. The resin, lamination and routing process still needs to match the board.

Do FCS router bits and guides work across every FCS system?

No. Fusion, FCS II and X2 installations use system-specific profiles and tools. Check the full product name and installation instructions before routing.

Can I replace a damaged fin plug myself?

A replacement needs correct alignment and sound foam or laminate around the route. If the area is crushed, wet or structurally damaged, have TSS or another experienced repairer assess it first.

TSS carries FCS plugs, boxes and installation tools for new builds and repair work. If the system or cant angle is unclear, contact TSS with photos of the fins, existing plugs and the board's fin layout.
