The F3 Bi MK-2 is a dedicated full reflex wing, that brings the best of what we have to offer to the tandem experience, now enhanced with the revolutionary Mohawk system.

Based on our F3, the F3 Bi MK-2 is a direct result of customer demand wishing for the same experience with their F3 paramotor wing in a tandem wing.

Now, with the addition of the patented Mohawk technology, we’ve taken stability and safety to a new level.

A solid, stable, easy to use wing that enjoys all the latest technology and the full range of performance that only a full reflex wing can offer.

Revolutionary Mohawk Technology

Mohawk (pat. pending) is essentially a stabilizer positioned at the center of the canopy. Drawing inspiration from various fins, it shares the same physical principles as a ship’s keel or airplane stabilizer.

The Mohawk measurably improves the wing’s roll stability and safety by acting as an auto stabilizing element whenever the wing is out of its flying axis. The Mohawk has a great aerodynamic advantage over “winglets” in that it is aligned with the flow on all Angles Of Attack.

An additional advantage of the Mohawk is safety related. The Mohawk will make any wing exit out of spirals spontaneously with no pilot input which is a very important safety feature for all wings. Spiral exit is fast but calm, slowly dissipating the energy.

Made out of Superlight materials, the Mohawk is an inflatable structure and stays solid throughout the flight envelope.

 

Main Features

• Available in 2 sizes.
• Fully functional accelerator/speed system  (for accommodating trikes)
• Pat. pending Mohawk  improves the wing’s roll stability.
• Pat. pending RollerCam® buckles for effortless trimmer control even with the heaviest trikes.
• Amazing Roll Stability powered by Apco’s Flow Aligned Ribs.
• Stabilo tip steering handles – easy to reach, light brake load for cruising.
• Apco’s legendary durability and long lasting materials.
• Huge speed range with a big chunk of it from the trimmers only.
• Apco’s FLEXON® battens,  indestructible, no need for special care or folding methods.
• Butt Holes2 – Passive cleaning of sand and debris from inside the wing.

Designed for both solo and Tandem Trikes, the F3 Bi MK-2 can also be used for foot launch* – the lighter load results in slower take-off speed, with minimum running.

F3 Bi MK-2 replaces its predecessor Lift EU delivering higher performance, while retaining the same safety and ease of use. Exceptionally easy launch and landing makes this the perfect wing for almost any qualified pilot looking for something more than what the LIFT Series offered.

As with the F1 and F3, incorporated into the F3 Bi MK-2 is our Flow Aligned Ribs (FAR) feature, morphing direction from center to tip, it aligns the ribs with the natural direction of the flow, increasing both performance and roll stability throughout the speed range. Combined with the Mohawk system, the roll stability of the F3 Bi MK-2 is especially impressive, allowing for agile, precise handling and perfect soft landings every time.

The canopy incorporates 2 functional “3D cuts” for the best possible leading edge shape definition. The canopy sail tension has been optimized to be a homogeneous unit, solid and reassuring in flight, resulting in our cleanest wing yet!

The riser / speed system / trim system was re-designed specifically for trike use, incorporating Apco’s groundbreaking riser technologies, and has a greater usable range than any tandem wing we have built before. A traditional speed system accelerator is incorporated into the risers for suitable trikes and doubles as an A-assist system when needed.

Open the trimmers and enjoy a significant speed increase of approx. 10 [km/h] (without the use of the speed bar). If your trike has the option to use a speed bar, you will be able to use maximum speed with the comfort of being able to come back to trim speed with ease, without taking your hands off the brakes or tip steering.

Construction – weight was saved wherever possible, bringing the weight down to 8.3 [kg], while retaining APCO’s legendary durability.

Positioned as the highest performing Reflex Tandem wing in our range, the F3 Bi MK-2 with Mohawk technology will easily satisfy every pilot graduating from a wing such as the LIFT or Hybrid Tandem, all the way up to competition pilots.

The glider is made from tear resistant Ripstop Nylon cloth, which is P.U. coated to zero porosity and then siliconized to give the fabric high resistance to the elements. Different cloth is used for the top, bottom and ribs due to their different functions. The lines are made of superaramid covered with a polyester sheath for protection against UV, wear and abrasion. The bottom section of the brake lines is made of polyester because of its better mechanical properties. The karabiners that attach the lines to the risers are made of stainless steel.
