Description

If you already ride Armstrong foils and want to move into the Duotone Foil Assist system without changing the foil feel you know and like, this is the key part that makes that possible. The Duotone eFuselage - Armstrong is the dedicated link between your Armstrong wing set and the Duotone Foil Assist ecosystem.

This is a smart choice for riders who want the clean, low-drag feel of Duotone Foil Assist, but do not want to rebuild their setup around a different foil platform. It gives you a neat way to keep your preferred Armstrong foil character while opening the door to assisted starts, longer runs and more time flying.

Where It Sits in the Range

This is not a complete foil or mast package. It is a brand-specific compatibility component for Armstrong riders building around Duotone Foil Assist.

Choose this fuselage if you already have, or are buying, a Duotone Foil Assist mast system and want to run an Armstrong wing set. If you are starting from scratch and want the simplest route into the system, it often makes more sense to begin with the Duotone Foil Assist Set AL or browse the wider Duotone Foil Assist range.

The key distinction is simple:

  • D/LAB mast users: this fuselage is the direct Armstrong-compatible option within the Foil Assist ecosystem.
  • AL / AL Cruise mast users: this fuselage works with those masts too, but you will also need the separate Duotone Fuselage Adapter.

Why Choose This Product

  • Keep your Armstrong foil feel: ideal if you already trust your current foil setup and do not want to start again.
  • Access Duotone Foil Assist properly: gives Armstrong riders a clean route into the Duotone assist system.
  • Less guesswork: purpose-built compatibility is better than trying to piece together a workaround.
  • Future-proof modularity: helpful if you want to build a Foil Assist setup in stages rather than buying everything at once.
  • Cleaner progression path: especially useful for riders moving into foil assist for downwind, prone, wake or light-wind wing sessions.

Helpful Reading & Buying Advice

FAQs

Will this let me use my Armstrong foil with Duotone Foil Assist?

Yes, that is exactly what this part is for. It is the Armstrong-specific eFuselage designed to make Armstrong wing sets compatible with Duotone Foil Assist masts.

Do I need anything else to use this with the aluminium Foil Assist masts?

Yes. If you are using the Foil Assist AL mast or AL Cruise mast, you will also need the separate Duotone Fuselage Adapter. If you are on the D/LAB mast, this is the Armstrong-compatible fuselage solution without that extra step.

Is this a complete foil setup?

No. This is a single compatibility component only. It does not include a mast, front wing, stabiliser, electronics or hardware unless clearly stated on your order.

Why would I choose this instead of switching to a full Duotone foil?

If you already know and like the way your Armstrong foil rides, this lets you keep that familiar feel while moving into the Duotone Foil Assist system. For many experienced riders, that is the most sensible and cost-effective route.

Who is this best suited to?

This is best for existing Armstrong riders who want to add Foil Assist for easier take-offs, more reps in marginal conditions, downwind help or longer flying time, without rebuilding their whole foil setup from scratch.

If you are unsure whether this is the right part for your exact mast and foil combination, get in touch with us before ordering. We would much rather point you at the correct setup first time.

Specifications
  • Features

    Armstrong-specific compatibility
    This fuselage has been developed specifically for Armstrong foil users wanting to connect into the Duotone Foil Assist platform. In plain English, it is the part that lets you bring your Armstrong wing set into the Duotone system rather than changing brand entirely.

    3BS connection
    The 3BS interface is what allows this fuselage to connect into the relevant Duotone Foil Assist mast setup. That matters because it keeps the system neat, secure and properly matched rather than relying on improvised compatibility.

    Works with all Duotone Foil Assist masts
    This is the important reassurance. If you are using the premium D/LAB mast, this is the Armstrong-compatible fuselage solution. If you are using the aluminium Foil Assist mast options, you can still use it, but you must add the separate adapter.

    60cm length
    This is the stated length for the Armstrong eFuselage. For most riders, the practical takeaway is that you are getting the dedicated geometry Duotone has designed for this Armstrong/Foil Assist crossover, rather than having to second-guess fit or balance.
