“I've had the original Hyper 12 since the 1980s. A power machine, always exciting to fly and sounds incredible. There is nothing else like it. So happy to see it is returning.” — James W., UK
60 seconds that explains why people can’t look away.
Real wind. Real noise. Real pilot. No tricks. If you’ve ever watched a kite and thought “I want that” — this is it.
The flight experience is identical whichever colour you choose.

Simply scan the clear downloadable illustrated instructions via QR code included on the bag and kite. Most people are airborne within 5–10 minutes of their first setup.
Precision Power Kite
Handcrafted in the UK. One of the largest Stacker kites Flexifoil has ever commercially made — back after 35 years. Cut and sewn individually by hand, inspected before it leaves our workshop.
225kg / 500lb Flying Lines Included Free
Every Hyper 12 includes a free set of 225kg / 500lb flying lines — everything you need to fly straight out of the bag. Padded wrist-straps are also included.
Free Worldwide Delivery
No surprises at checkout. Dispatched by courier. Shipped to you in around 10 days from order, usually arriving within a few days depending on distance from the UK.
Flying Lines
Available as an add-on in case you already have a set. If you need flying lines, simply add the set that corresponds to the number of kites you plan to stack. It is that easy.
Lifetime Money-Back Guarantee
Fly it. Love it. If not — for any reason, at any point — send it back for a full refund.
World Record-Proven Design
The Hyper 12 shares its design DNA with the Super 10 — the world's fastest kite at 120mph / 193kph. At 12ft, the power is in a different category entirely. This is the kite that experienced pilots have been asking for since it disappeared from the range 35 years ago.
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.
One kite is extraordinary.
Two kites is a different world entirely.
The Hyper 12 stacks — but this is not a kite you add to casually. A single Hyper 12 generates the pull of three Super 10s. Two Hyper 12s in sensible winds is about as much power as most experienced pilots will ever want. Build your stack gradually, reduce immediately if it feels too powerful, and always fly with an experienced companion present.
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
“Have been looking for a second Hyper 12 for years so was very happy to hear Flexi is bringing them back. This is a really powerful kite and gets your adrenalin pumping! Cannot wait!”
Mark T., Australia
“I've been flying Flexifoil kites for over 30 years and recently bought a new Super 10. The Hyper 12 is the one that got away and was discontinued before I had the chance to own one. Getting my hands on a brand new one is something I genuinely didn't think would happen. Super stoked it's coming back! Flexifoil are back at the top of their game.”
Neil P., 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 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. A single Hyper 12 generates the equivalent pull of 5 Stacker 6s combined. Imagine what a stack of those feels like.
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 × Hyper 12 = 3 × Super 10
1 × Hyper 12 = 4 × Pro-Team 8
1 × Hyper 12 = 5 × Stacker 6
The Hyper 12 is an expert-level kite. Always place the Hyper 12 at the top of any mixed stack and use the Hyper 12 line strength specification for the entire stack. Never stack without first flying solo in lighter winds and building up gradually.
How to Stack
- Start with one Hyper 12 flying solo — always in lighter winds first
- Add a second kite using stacking lines — clip to the leading edge, launch, and feel the pull. The Hyper 12 in a stack generates extreme force. Be prepared.
- Build your stack one kite at a time. If it feels too powerful at any point, reduce the stack immediately
- Experience one of the most powerful 2-line power kites available anywhere in the world
Stacking lines rated to 500lb / 225kg minimum are required for the Hyper 12. 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.
