“I've been mountain biking for 20 years. Flew this on a rest stop. Three riders pulled over just to watch - none of them had seen anything like it.” — Rob T., UK
60 seconds that explains why people can’t look away.

World Record-Proven Design
The Stacker 6 shares its DNA with the world's fastest kite design — part of the same lineage that achieved 120mph / 193kph. The current kite is a direct descendant of that record-breaking design.
Handcrafted in the UK
Built individually, not mass-produced. Each kite is inspected before it leaves our workshop.
Quick & Easy Setup
Connect the spars, attach the lines, clip the handles. Clear illustrated instructions included. Most people are flying within 5–10 minutes the first time.
Built for people who already love wind, speed & the outdoors.
You don’t need to be a kiter. You just need to spend time outside. This fits.
Mountain bikers
You know what it’s like when your ride clicks. This is that feeling — different terrain, same flow state. Fly it in fields or on beaches. Anywhere there’s wind and wide-open space.
Dinghy sailors
You understand power in a sail. The pull at gust? You’ll recognise it immediately. Except there’s no boat to capsize this time.
Kiters & outdoor enthusiasts
You’ve seen cheap kites wobble and crash. This kite flies in winds that fold the competition. This is what properly built feels like. People stop and watch every time.
One kite is brilliant.
Two kites is a different sport entirely.
These kites are engineered to stack. Connect them in series and the pull doubles. Experienced pilots run two, three or even six in lighter winds.
Trusted by record-breakers. Made for everyone.
BBC One
Flexifoil kites were filmed for a BBC One ident specifically because the kite in flight was too striking not to use. That’s not paid advertising. That’s a kite that earns its place on national television.
Guinness World Records
Sir Richard Branson and his family set three kiting world records using Flexifoil kites. Three records. One weekend. The Flexifoil name is visible throughout the press backdrop.
What people say.
“I was really excited to see Flexifoil International re-launch the full range and sizes of their iconic Stacker Series kites. I've been equally excited when my new kites arrived and I have been impressed with the fabrics used, the quality of construction, and the print capability. Importantly, the flight capability and fun factor of the new range is excellent! FULLY RECOMMENDED!”
Guy R., UK
“I didn't expect kite flying to be this fun, but this foil kite really surprised me. It's intuitive to control, the quality feels really solid, not flimsy or cheap. I'd definitely recommend giving it a go. Plus, the money-back guarantee makes it feel like there's nothing to lose.”
Jon P., USA
“I've been having a great time flying this kite at the beach. I was getting the hang of it within about 15 minutes. I definitely crashed it while learning, but it held up perfectly, no damage at all. It's a really fun, well-made kite. Even my neighbour ended up buying one after flying mine!”
John V., UK
293 kites.
One stack.
They disappeared
into the sky.
In 1994, on the beach at Le Touquet, France, a team launched a stack of 293 Flexifoil Stacker kites — the kite you're looking at today. The first 10 kites went up. Then the next 10. The power of those already flying pulled the rest into the air. The stack climbed until the kites were barely visible against the clouds — a thread of colour dissolving into the grey French sky.
The pull was so immense that industrial heavy machinery was brought in as anchors. Custom pulleys. Tension rigs built for the occasion. The tide was coming in fast. This is what the Stacker kite becomes when you let it stack.
Start with one. Stack when you’re ready.

POWER COMPARISON
1 × Super 10 = 3 × Stacker 6
1 × Pro-Team 8 = 2 × Stacker 6
2 × Super 10 = 3 × Pro-Team 8
You can stack a mix of Stacker 6s, Pro-Team 8s and Super 10s. Always place larger kites at the top of the stack and use the line strength for the largest kite size in your stack.
How to Stack
- Start with one kite flying solo
- Add a second kite using stacking lines — clip to the leading edge, launch, and feel the pull double
- Build your stack — 2, 3 or 6. Always add one kite at a time. If it feels too powerful, reduce the stack
- Experience the speed, sound and lift of true aerial performance
Stacking lines and upgraded line sets are available in our store.
Setup Instructions
Full illustrated instructions are included via a QR code printed on the bag and replicated on the kite itself. Scan to download a clear PDF guide. Most people complete first-time setup in 5–10 minutes.
Questions people ask before they buy.
How long does it take to set up?
What does the setup actually involve?
- Connect the spars — the rigid rods that give the kite its shape. They slot together and slide into the kite. About 60 seconds.
- Unwind and attach the flying lines — pre-measured, attach to the kite as per the instructions. About 90 seconds.
- Attach the handles — your padded wrist-straps clip to the ends of the flying lines.
