The Foil Drive Assist Slim Base Kit is the core of the Assist Slim system, and it comes without a motor or battery. It’s ideal for riders who are installing an integrated mast, already own Slim components, or prefer to build their setup piece by piece. The Slim is the thinnest model in the range. It preserves the weightless feel of the foil while delivering the same peak power as the Assist MAX.

DETAILED DESCRIPTION
Three reasons to buy a base kit
First, consider an integrated mast. When you invest in an integrated Foil Drive mast, the motor is already housed within it. Buying a complete kit would mean paying for a second motor that would remain unused. Second, this kit is perfect for equipping an additional board: if you already own Slim batteries and motors, this housing is all you need to build a second complete setup. Third, it offers the freedom of configuration. Choosing your own motor, battery, and cable length gives you a system tailored to your needs, rather than a factory compromise.
The Slim's character
The Slim is not a cut-down version of the Assist MAX. It delivers the same peak power in a thinner casing. What changes is the range: Slim batteries are more compact, so the run time is shorter. The Slim is made for brief, powerful bursts, those that get you on the foil before giving way to pure glide. Riders who prioritize responsiveness, agility, and pumping will find what they need here. Those who want to ride for a long time with the motor should look at the Assist MAX.
Choosing your motor and battery
For the motor, the standard v2 covers general use, while the high power v2 provides more torque for heavier riders or larger volumes. For the battery, the Slim Performance is mounted in pairs for extended range, the Slim Travel is approved for air transport, and the Slim Endurance is designed for long sessions. The motor cable length is chosen according to the mast height and can then be changed in seconds thanks to the removable v2 cables.

FAQ
What else do you need to ride?
You will need a v2 motor, either standard or high power, and a Slim battery. The controller will not function without these two components. If you choose an integrated Foil Drive mast, the motor is already included, so you only need to select a battery. The corresponding charger for your battery is also necessary.
Slim or Assist MAX?
Both deliver the same peak power. The Slim is thinner, lighter, and has less drag, but its batteries offer less range. Choose the Slim if you are looking for take-off followed by glide, whether you're Surf foiling, winging, or doing downwind runs. Opt for the Assist MAX if you want to ride with the motor for extended periods.
Will it fit my foil?
The included universal mast adapter fits almost all masts on the market. However, some unusual mast profiles may require a specific motor pod or adapter. If you are unsure about your mast, contact us before ordering, and we will verify compatibility with you.
