Flexifoil Proton 2 Kitesurf Kite
Technical Information
Developed from a starting point of excellence, and modelled through the skills and experience of the Flexifoil design team, with influence from one of the world’s finest team of riders, the Proton is an incredible technical achievement.
The Proton Has been carefully fettled and tuned and with the Flexi team Listening to what their customers want the development of a kite system that does exctly what you want it to is embodied in the Proton Second generation.
Stability and Predictability
The Proton has been designed to maximise stability through a naturally ‘nose-up’ position that wont fall from the sky unexpectedly. Furthermore, the powerful profile, coupled with mid-aspect ratio provide a balanced bar pressure making the kite very forgiving and easy to feel. Whether you’re a beginner or an expert, you’ll find the Proton the perfect confidence boost to develop your skills.
Versatility in Performance
The Proton’s solidity in its power make it great for freestyle tricks, whilst sharp depower and snappy turning make the kite great in waves. An overall reliable performance with predictable flying characteristics make it a superb free-riding kite, rounding the Proton off as the ultimate in versatility.
Safety First
Your safety is a top concern, consequently, the Proton continues the use of Flexifoil’s persistently successful primary release system present on all water kites. Capable of killing 90% of the power in one swift action, you can be confident on the water at all times. In addition, colour coded lines are used to ensure simple and safe setup, as well as the option of the 5th line for added safety and self landing.
Thorough Testing Reinforcing Quality
Flexifoil’s new Leading Edge construction standards have surpassed previous inflation test results by almost 40%, and with crash testing completed in the Sahara desert, you can be sure that you’re flying a kite suitable for even the worst beginners!
Exceptionally Intelligent Design
The Proton’s rigid strut system creates a stronger, more accurate and neater kite than ever before, adding to the rigid feel and excellent bar feedback. The diameters of the struts have also been carefully considered to ensure adequate stiffness and their positioning has been optimised to produce uniform pressure throughout the kite and maximise aerodynamic performance.
Strength is built throughout the kite thanks to the Dacron cage protecting high stress and wearable areas. Meanwhile, leading edge Kevlar/Neoprene reinforcements have been used to protect every circumferential seam with wear patches placed on any potential wear points near the toggles to maximise protection when in contact with the beach.
The Proton’s aerofoil is designed to provide powerful boost, good low-end performance, lots of depower and make the kite resistant to back-stalling by using an aerofoil that will naturally “nose-up” when the lines go slack.
Clever Features Inspired by You
We aim to make your life as simple as possible; our E-Z Inflation single point system means you have less work to inflate the kite. For this year’s kites, Flexifoil has also included wingtip dump valves on each wing tip to make packing down easier and quicker. Little changes here and there mean you’re first on the water and last out.
With The Essential dynamcs dialed in on the Kite the focus turns to the Build of the Kite, Flexifoil Have allways been renowned for their superior build quality but with the launch of the second series Proton they have surpassed all expectation and built a technically superior Kite System.
The Wingtip Design has been significantly modified for the 2nd generation of kites and so enables faster turning speed and exceptional re-launch.
The Dacron Cage has been re thought making all 90 Degree Angles in the canopy a thing of the past improving airflow through the canopy.
Advanced wear protection on the leading edge. Modified Positioning on the leading edge in the more prone to wear zones means the kite is better equipped to deal with harsh landings and general wear and tear on the beach.
Trailing Edges have Been Modified to Make the Airflow through the Canopy to allow Better flying dynamics and a weight saving in the 12M Size.
Adapted Bridles, The shortened length and re placement of the bridles makes for more depower and a smoother ride with progressive power delivery. also there is less bridle to get tangled in the surf.
Brilliant!

Just started teaching on this kite, it is amazing! Great air time, easy relaunch, both of which surprised me, because it is so well built that we thought it would be a tank!
Come demo one with us, we are usually down on Shoreham beach flying them when it's windy- www.thekitetrip.co.uk then grab yourself one from S2AS!
