What to Look for in an Integrated Flight System
Before choosing a system, it’s worth understanding the key differences between products.
Rigidity vs Flexibility
Integrated systems fall somewhere on a spectrum between rigid and flexible. Rigid systems maintain their shape better and last longer, but can cause deflections when darts group tightly—the incoming dart bounces off the rigid flight rather than pushing it aside. Flexible systems bend on impact, reducing deflections and allowing tighter groupings, but may wear faster and can affect stability for hard throwers.
Most modern systems aim for a middle ground: firm enough for consistent flight, flexible enough to reduce deflections.
Flight Shapes
Most systems offer No.2 (standard) and No.6 (smaller) flight shapes. Some also offer Slim options. Larger flights provide more lift and stability, while smaller flights allow tighter groupings and faster flight speeds. Your choice depends on throwing style—softer throwers often benefit from larger flights, while hard throwers may prefer smaller profiles.
Stem Lengths
Integrated systems typically come in Short (19-23mm), Intermediate/Tweenie (26-28mm), and Medium (33mm) lengths. Longer stems shift the centre of gravity rearward, promoting a more stable, nose-down flight. Shorter stems suit players who prefer a flatter trajectory.
Weight
Integrated systems are generally heavier than traditional stem and flight combinations. This affects the overall balance of your dart—lighter systems (around 1.3-1.5g) have less impact on your setup, while heavier options may require adjustment.
The Products
Target K-Flex
The Target K-Flex is the system that brought integrated flights into the mainstream, thanks largely to Luke Littler’s success using them. The K-Flex uses precision injection moulding to fuse flight and shaft into a single lightweight unit.
The K-Flex is notably lighter than competitors—a key selling point for players who don’t want to significantly alter their dart’s balance. The shaft section is designed to flex on impact, reducing bounce-outs when hit by incoming darts. The flight portion increases slightly in thickness from front to back, improving durability over time.
Target offers an extensive range of colours and player editions, including collaborations with Luke Littler, Rob Cross, Nathan Aspinall, and Raymond van Barneveld. The system uses a universal 2BA thread for maximum barrel compatibility.
Key Features:
- Lightweight design (lighter than most competitors)
- Flexible shaft section reduces deflections
- Precision-moulded 90-degree flight angle
- No.2 and No.6 shapes available
- Short, Intermediate, and Medium lengths
- 2BA universal thread
- Wide colour range including player editions
Online Consensus: The K-Flex is praised for its lightweight feel and affordability compared to the Condor Axe (often cited as the original premium option). Users report good durability, though some note the flexible design means they’re not quite as long-lasting as more rigid alternatives. The price-to-performance ratio is frequently highlighted as excellent.
View on AmazonRed Dragon Nitro
The Red Dragon Nitro Flite is Red Dragon’s entry into the integrated flight market, launching in early 2025. It uses a dual-core polycarbonate construction designed for strength and consistent flight characteristics.
The Nitro features an aero-grade design intended to provide a smooth, stable flight path with reduced deflection. The dual-core construction means the shaft and flight portions use different material densities—firmer in the shaft for durability, slightly more flexible in the flight section.
Currently available in No.2 shape only, with Short, Intermediate, and Medium lengths. Colour options include Black, White, Blue, Yellow, Red, and Clear, with two-tone combinations available.
Key Features:
- Dual-core polycarbonate construction
- Aero-grade precision design
- No.2 shape (standard only currently)
- Short, Intermediate, and Medium lengths
- Two-tone colour options
- Approximately 1.5g weight
Online Consensus: As a newer product, feedback is still developing. Early reviews praise the build quality and aesthetics. The main concern raised is durability when dropped—several users report the shaft snapping just below the flight section on hard floor impacts. However, during normal play, durability appears solid. The limited shape options (No.2 only) restrict appeal for players preferring smaller flights.
View on AmazonWinmau Fusion
The Winmau Fusion launched as part of Winmau’s 2024 product line and offers a compelling balance of performance and value. The system uses advanced polymers with carved grooves in the shaft section, providing flexibility where it matters while maintaining rigidity in the flight.
The Fusion’s design focuses on deflection control—the slimmer stem and longitudinal grooves allow the system to move aside when struck by incoming darts, reducing bounce-outs without sacrificing the perfect 90-degree wing angle.
Available in No.2 and No.6 shapes across multiple lengths and a wide range of colours including neon options.
Key Features:
- Advanced polymer construction
- Grooved shaft for controlled flexibility
- Perfect 90-degree wing design
- No.2 and No.6 shapes available
- Multiple stem lengths
- Industry-leading deflection control
- Neon colour options available
Online Consensus: The Fusion receives strong praise for its value proposition—often available at around half the price of Condor Axe systems while offering comparable performance. Users appreciate the balance between rigidity and flexibility. Some concerns exist about the hard plastic potentially cracking under heavy impact, though this appears infrequent. The bright colour options divide opinion—some love them, others find them too garish.

The Mission Force 90 is one of the top-selling integrated systems and offers excellent value. Made from high-grade composite material, the Force 90 maintains a perfect 90-degree angle between fins throughout its playing life.
The flights feature smooth edges designed to reduce deflections and improve aerodynamics. A textured grip zone on the stem aids players who hold the shaft during their throw. The name “Force 90” refers to the consistent 90-degree angle the system maintains.
Ritchie Edhouse switched to Force 90 flights in April 2024 and subsequently qualified for the World Matchplay and World Grand Prix for the first time, before winning his first major title at the European Championship—though correlation and causation are, of course, different things.
Available in No.2, No.6, and Slim shapes, each in Short, Tweenie, and Medium lengths, with gradient colour options alongside solid colours.
Key Features:
- High-grade composite material
- Smooth-edged flights for reduced deflection
- Textured grip zone on stem
- No.2, No.6, and Slim shapes
- Short, Tweenie, and Medium lengths
- Gradient colour options
- Used by Ritchie Edhouse
Online Consensus: The Force 90 is frequently recommended as the best value option in the integrated flight market. Users praise durability and the variety of shapes available. Some report them as slightly more flexible than K-Flex, which suits players prioritising tight groupings. The grip zone is appreciated by those who use it, though it’s irrelevant for players who grip only the barrel. At around £6-7 per set, the value proposition is strong.
View on AmazonUnicorn Forge
The Unicorn Forge is built from low-density polymer with advanced longitudinal shaft grooves designed to maximise dart groupings. Unicorn emphasises the rigidity of the Forge system as a key feature—it provides a highly consistent flight path with minimal variation.
The Forge balances rigidity with enough flexibility for force absorption, reducing deflections while maintaining the stability that comes from a stiffer construction. The one-piece design ensures the 90-degree angle is maintained permanently.
Unicorn’s heritage in darts (21 World Championship wins across their sponsored players) lends credibility, though of course the Forge must stand on its own merits.
Key Features:
- Low-density polymer construction
- Longitudinal shaft grooves
- High rigidity for consistent flight
- Force absorption design
- Standard Plus shape available
- Multiple colour options
Online Consensus: Reviews are somewhat polarised. Satisfied users praise the improved trajectory and stability, with several reporting notable improvements to their grouping. However, durability concerns exist—some users report thread splitting issues, particularly when the stems fit tightly into barrels. The rigid design suits players who prioritise consistent flight over maximum flexibility, but those who group very tightly may experience more deflections than with softer alternatives.
View on AmazonCuesoul Rost
The Cuesoul Rost (also known as the AK5) is a budget-friendly option from the Chinese manufacturer. The system uses a dual-material construction—the AK7 material in the shaft and thread provides toughness and shape retention, while the AK5 material in the flight section maintains flexibility to avoid damage from incoming darts.
The Rost offers an impressive variety of flight shapes: Big Standard (1088mm²), Big Wing (1048mm²), Slim (739mm²), and Kite (887mm²). This range caters to different throwing styles and preferences more comprehensively than most competitors.
Weights range from 1.38g (Short) to 1.57g (Long), making them mid-range in terms of impact on dart balance.
Key Features:
- Dual-material construction (AK7 shaft, AK5 flight)
- Four flight shapes available
- Short (23mm), Medium (28mm), Long (33mm) stems
- Precision-moulded 90-degree angle
- Budget-friendly pricing
- Wide colour variety
Online Consensus: The Rost is praised as a cost-effective entry point into integrated systems. Users report smooth flight characteristics and good barrel retention—they stay tight in the dart. Durability is described as comparable to other moulded systems, with some edge wear developing over time and occasional splits on leading edges after extended use. The variety of shapes available is frequently highlighted as a strength. Direct shipping from China means longer delivery times but lower prices.
View on AmazonShould You Switch to Integrated Flights?
Integrated systems offer genuine benefits: consistent 90-degree angles, no loose stems, no popped flights, and protection against robin hoods (where a dart point enters another dart’s flight). They simplify your setup and reduce the accessories you need to carry.
However, they’re not universally superior. The rigidity that provides consistency can cause deflections for players who group tightly. Traditional flights “give” on impact, absorbing energy—integrated systems transfer that energy, potentially pushing incoming darts off target.
Consider integrated flights if:
- You’re tired of tightening stems and replacing damaged flights
- You want guaranteed 90-degree angles for consistent flight
- You don’t group extremely tightly (leaving space between darts)
- You prefer a simpler, lower-maintenance setup
Stick with traditional flights if:
- You group very tightly and experience deflection issues
- You prefer the feel of traditional stems
- You like frequently changing flight shapes and colours
- You’re on a very tight budget (traditional flights are cheaper per unit)
Currently, only around 6 of the top 32 PDC players use integrated systems—the majority still prefer traditional setups. This isn’t a verdict on quality, but rather evidence that personal preference plays a significant role.
Summary
Best overall: The Target K-Flex offers the best combination of lightweight design, flexibility, durability, and brand support, with extensive colour options and professional player backing.
Best value: The Mission Force 90 provides comparable performance to premium options at a lower price point, with excellent shape variety including Slim options.
Mid-range option: The Winmau Fusion delivers solid performance at a competitive price point, making it ideal for players wanting a reliable integrated system without premium pricing.
Most variety: The Cuesoul Rost offers the widest shape variety (four different shapes) at mid-range prices, ideal for experimenting with different configurations.
For rigid flight paths: The Unicorn Forge suits players who prioritise consistency over flexibility, though durability concerns exist.
Newest option: The Red Dragon Nitro brings quality construction but limited shape options currently restrict its appeal.
Frequently Asked Questions
What are integrated dart flights?
Integrated dart flights (also called all-in-one flights or moulded flight systems) combine the flight and stem into a single piece of moulded plastic. Unlike traditional setups where flights slot into separate stems, integrated systems maintain a permanent 90-degree angle and eliminate the need for flight protectors or stem tightening.
Are integrated flights better than traditional flights?
It depends on your playing style. Integrated flights offer consistency (perfect 90-degree angle every time), convenience (no loose stems or popped flights), and protection against robin hoods. However, they can cause more deflections for players who group very tightly, and they’re more expensive per unit than traditional flights. Around 80% of top PDC players still use traditional setups.
What integrated flights does Luke Littler use?
Luke Littler uses the Target K-Flex integrated flight system in the No.6 shape. His signature edition K-Flex flights feature his fluorescent yellow and purple colour scheme and are available from Target Darts and most UK darts retailers for around £12.95.
Which integrated flights are best for beginners?
The Mission Force 90 offers the best value for beginners at £6-7 per set. It’s available in multiple shapes (No.2, No.6, and Slim) so you can experiment with different profiles, and the textured grip zone helps if you’re still developing your grip technique.
How long do integrated flights last?
With regular play (3-4 times per week), most integrated flights last 2-4 weeks before showing significant wear. More rigid systems like the Unicorn Forge tend to last longer but may crack under heavy impact, while flexible systems like the K-Flex wear more gradually but are less prone to sudden breakage.
Can I use integrated flights with any darts?
Yes, all the integrated flights reviewed here use the standard 2BA thread fitting, which is compatible with the vast majority of steel-tip darts. Simply screw them into your barrel as you would a traditional stem.
