About This Kite

The Flexifoil Stacker 6ft is the original power kite and virtually indestructible; it is the perfect starter kite. It has achieved record breaking speeds of 193kph / 120mph. It is the smoothest way to power. One is good, many are better. Stack them for ultimate power adjustment.

• Lightning-fast turns, manageable pull — pure fun even in strong wind
  
  
• Perfect for beginners, pros, and everyone in between
  
  
• Easy to stack — create your own high-speed flying display
  
  
• Suitable for ages 12+ under adult supervision. When stacking, an adult should test the power of the stack to ensure the 'under 18' is capable of flying it in a controlled and safe manner.

Buying Your First Kite? Start Here.

If this is your first Stacker 6, we recommend purchasing it with the ideal line set for 2-kite stack flying:

40m / 130ft – 90 kg / 200lb Flying Line Set + Padded Wrist Straps

This setup is perfect for learning the basics and building confidence on your own.

Thinking About Stacking Later? (See table below for specifications)

If you plan to stack multiple Stacker 6' kites in the future, you’ll need stronger flying lines to handle the extra power.

For example, if you eventually want to fly 5 'Stacker 6' kites stacked together, go for:

40m / 100ft – 135kg / 300lb Flying Line Set

Make sure to choose the right flying line set based on how many kites you plan to stack — now or later. Keep in mind: the stronger the line, the heavier it is. That means it requires more wind and power to fly. So if you're flying just one Stacker 6' on lines designed for a 10-kite stack, you'll need significantly stronger winds.

Flying Line Sets and Padded Wrist Straps

To keep things flexible (and more affordable for returning customers), we offer flying line sets and padded wrist straps for control as optional add-ons.

Many fliers already own a set and don’t need duplicates. By offering them separately, you only pay for what you actually need. 

If you're new to Flexifoil or kiting in general, we recommend adding a flying line set and padded wrist straps with your first kite so you're ready to fly right out of the bag.

Make sure to choose the right flying line set based on how many kites you plan to stack — now or later. Keep in mind: the stronger the line, the heavier it is.

Power Comparison

Compare the relative pulling power of the Flexifoil Power Kite range:

1 × Super 10 = 3 × Stacker 6

1 × Pro-Team 8 = 2 × Stacker 6

2 × Super 10 = 3 × Pro-Team 8

You can fly Flexifoil Power Kites individually or join them together and build yourself a MONSTER POWER STACK.

You can stack a mix of Flexifoil Stacker 6’s, Pro-Team 8’s and Super 10’s. Always make sure that the larger kites are at the top of the stack and use the line strength stacking specification for the largest kite size. So if you were stacking Stacker 6’s and Pro-Team 8’s, you would use the Pro-Team 8 line strength stacking specification. Or if you were stacking Stacker 6’s, Pro-Team 8’s and Super 10's, you would use the Super 10 line strength stacking specification.

You will find all the recommended kite flying lines in the flying line section of the store.
