Slingshot’s zero-strut foil kite just got its fourth-generation update. If you’ve flown a UFO before, this isn’t a reinvention – it’s a refinement of everything that made the line popular, tightened up exactly where foil riders feel it most.

Quick Answer: What’s New on the UFO V4?

The Slingshot UFO V4 is a zero-strut, foil-specific kite updated with a thinner leading edge, lighter bar pressure, more refined steering, better toeside/downwind drift, and a higher aspect ratio on larger sizes. It’s built for foilers who want a kite that flies with minimal input and holds its position reliably at low, drifted angles.

What UFO V4 Actually Changes

A thinner leading edge. This is the core structural change driving most of the other improvements — a slimmer LE generally cuts drag and lightens the kite’s overall feel in the air.

Lighter bar pressure and refined steering. Slingshot says the kite is now easier to place precisely in the wind window and feels more natural for the small, constant corrections foiling demands — including flying one-handed while managing a board or making other adjustments.

Better toeside/downwind drift. This is the big one for foil riders. Slingshot says the V4 holds its position more consistently when riding downwind toeside, with less tendency to fall out of the sky — meaning less energy spent babysitting the kite and more spent on line choice, body position, and flow.

Higher aspect ratio on larger sizes. Bigger UFOs now use a higher-aspect shape, generally improving efficiency and hang time in lighter wind — useful since foil sessions often happen in marginal breeze.

Carried-over construction. DLE 140 leading edge material, a D2 canopy reinforced with D4 fabric at the leading edge, DCPRO401 bridle lines, and an HP valve — all aimed at keeping the kite light, durable, and quick to pump.

Who the UFO V4 Is For

Slingshot positions this kite specifically for:

• Riders who want a foil-specific kite with strong drift, light bar pressure, and intuitive steering
• Riders who spend real time downwind or riding toeside and need a kite that stays flying without constant input
• Riders who want a lightweight, efficient kite that’s easy to place and easy to trust
• Anyone upgrading from an earlier UFO who wants the next step in Slingshot’s zero-strut design

It’s not marketed as a big-air or freestyle kite — it’s built to disappear in your hands so you can focus on the foil.
