The Foil Drive Assist MAX+ takes everything that the world loved about our most popular foil assist and evolves it into the latest Gen 2.5 class, turning up thrust, runtime, and safety features to unlock autonomy across all foiling disciplines.

Built around the same proven 43V power, tech, and charging architecture of the Fusion, the MAX+ offers our most durable one piece battery design, all while retaining the compact, lightweight and balanced package that made the original MAX so versatile.

Unlock smaller foils, boards, performance, faster take-off, and more time on the water with tilt-safety cut off features that makes this same retrofit kit so family friendly.

The lightweight balance that made MAX the all rounder remains, while everything around it has evolved.

Riders can enjoy a sportier feel without compromising on thrust and boost thanks to the NEW FM+650 Battery (650Wh) and early in 2027 the even smaller, FM+430 Battery.

DETAILS

The Assist MAX+ is built for riders who want the best all-around system that can open up every side of foiling.

• Spend over an hour flying through surf and riding waves. 
• Motor upwind to unlock downwind runs without a shuttle
• Practice pumping without wasting energy on repeated tow or surf starts
• Chase wakes from passing boats
• Extra thrust to get onto smaller foils and boards with more confidence and runtime.

From tiny bumps to the biggest waves of your life, MAX+ gives you the freedom to keep flying regardless of the conditions. Surf, lightwind wing, downwind, wake, flatwater or eFoiling, it adds more power, runtime and range to practically any existing foil setup you have already or want to ride, making every session easier to access, more productive and more fun.

KEY FEATURES OF THE FM+ 650 BATTERY

• Gen2.5 Battery Technology allows the rider to utilise the battery for longer. The battery is able to perform “deeper” into the cycle, meaning on water you’ll be able to enjoy the full power delivery right down to ~10% battery before you begin to notice the “sag” that all batteries experience.
• Charging 
  The FM+650 Battery requires 43V Charger (Provided with your Fusion or MAX+ System) to charge. Averaging 85 minute charge time with an industry first Storage Mode that allows you to limit charging to then store your batteries for long-term battery health. We recommend storing you battery between 30 and 60% State of Charge (SoC).
• Intelligent Bluetooth Module (BMS) provides accurate battery data to the V3 Controller, giving clear percentage and status readouts. The Battery also connects to the Foil Drive App where you can name each battery, track its health and view it's battery State of Charge (SoC). Check the surf camera and your battery charge without lifting a finger!
• One-piece molded design combines the battery and nose cone as a unified sealed unit.
  The integrated one-piece molded design combines the battery and nose cone as a unified sealed unit, improving water flow, and durability, all while balancing weight directly over the foil’s center of lift.
• Internal thermal management keeps temperature stable and maintains consistent power through the full discharge curve, ensuring smooth thrust delivery from start to finish.

ARMSTRONG FOIL DRIVE Foil Assist Integrated Carbon Mast

Seamless power assist meets signature Armstrong feel.
Fully Integrated, freakishly smooth.

The Armstrong Foil Drive Integrated Foil Assist Carbon Mast redefines what’s possible with powered foiling. Unlike standard integrated systems, this setup is purpose-built to reduce drag and unlock a smoother ride from takeoff to touchdown.

For beginners, that means easier lift and no more sudden stalls when the motor pod hits the water. For advanced riders, it’s seamless wave performance, which can glide through without experiencing drag or stopping abruptly, unlike with standard designs, where hitting the motor pod can cause you to bog.

Whether you’re chasing bumps on windless days or just starting out, it turns small waves into endless sessions with unmatched performance.
