IBEXsquirrel_ibex_image

The IBEX is our lightweight / low-bulk wingsuit BASE canopy. It is equipped with two Mini-Vents, which are a standard option. The IBEX is designed specifically for wingsuit BASE jumpers for whom low-volume is a main priority.

Our mission for the IBEX was to create a canopy that delivers progressive openings, solid glide performance, and nimble handling. The IBEX is the result of a wide collaboration between Squirrel engineers, team pilots, and partners with many decades of combined para-foil design, construction, and testing experience. We think the two bottom surface mini-vents, which are included standard, provide just the right amount of inflow during the opening sequence and make this a highly versatile canopy.

Details

Construction-The IBEX main surfaces and ribs are made from Porcher Sport PN9*, widely considered to be the highest quality ultralight low porosity parachute fabric available today. The IBEX was load tested by Para-Test of Switzerland at above max load in slider on and slider off configurations.

Lines- The 725lb Spectra line option is ideal for wingsuit pilots who put priority on weight, performance, and low-volume. Spectra lines are available in white only. In the Dacron option, a blend of 400/525lb lines yields an excellent balance of durability and opening behavior for a wider range of uses, including tracking and slick jumps. Dacron lines are available in black only, with the exception of the steering lines which come in white only.

Handling- The Squirrel test team worked hard to perfect the relationship between opening, glide performance, and deep-brakes behavior in the IBEX. The profile that we chose has a long track record of reliable performance, and the standard ZP leading edge aids opening, glide, and flare performance. We wanted a wing that would provide excellent glide, but also yield slow-speed maneuverability and we hope you agree that the IBEX’s deep brake behavior and lower-end flare is worthy.

Openings- Two standard Mini-Vents encourage a faster and more progressive inflation. To tune your openings, choose the size and type of pilot chute and slider that works best for your gear configuration, and adjust your airspeed before deployment.

Slider Down Use- The IBEX is specifically designed for terminal slider-up wingsuit BASE jumps. It is acceptable for only occasional slider-off use by experienced jumpers. Both the Spectra and Dacron line sets have been tested for slider-off use, but the IBEX is not designed to be used by low-experience jumpers for slider-off BASE jumps. The IBEX is not designed to be used for static line BASE jumps.

Weight and Pack Volume- Porcher Sport PN9 is the industry standard for lightweight and low-bulk parachutes, and while the IBEX is special in a few ways, it is not a wild departure from other similar canopies in its class. The weight and pack volumes remain consistent with other modern lightweight BASE parachutes. Please note that the IBEX packs into a low-volume configuration and must only be used in appropriately sized containers.

OUTLAWsquirrel_outlaw_image

The OUTLAW is a versatile BASE canopy that excels in technical landing areas. It contains real innovations in BASE canopy design that can be seen and experienced.

The OUTLAW is not designed especially for only one type of jumping. Instead of creating a highly-specialized canopy, our focus was on a new type of versatility made possible by low freefall specific features and reefing devices for terminal openings. The OUTLAW is a user-friendly design that performs well in a vast range of applications for all qualified jumpers.

These advances in BASE parachute technology are tangible features that yield real results. Scroll

A-Chord line mini-vents allow for forward a-line attachment points- The OUTLAW’s leading edge design was chosen for its balance of inflation speed and efficiency. By extending the top surface more into the leading edge, we increased the OUTLAW’s efficiency and performance at trim speed and deep brakes. We also extended the bottom surface into the leading edge in order to place the A-line attachment points as far forward as possible, to increase pitch stability. This would otherwise reduce nose opening size, so in order to maintain excellent nose-inflation during the opening sequence, five mini-vents were added to the A-chord line. This gives us the best of both worlds: a performance nose design, with rapid inflation and high stability. It adds up to increased pitch stability during inflation, canopy flight, and landing.

Rear-Chord Float-Flaps increase laminar flow in deep brakes- Inspired by a paraglider design, this key innovation allows low stall speeds and forgiving slow-speed characteristics. The OUTLAW excels in steep approaches using deep brakes. Spanwise tension in the canopy and a 3D-shaped differential cut between the top and bottom surfaces keep the Float-Flaps closed while the canopy is in trim flight, meaning that the OUTLAW’s glide performance is not compromised. With brakes applied, profile camber increases progressively and opens the Float-Flaps, allowing some air to escape and add laminar airflow to the top surface of the canopy in the location that stall begins. This airflow stabilizes turbulence over the top surface and provides a smooth transition to deep-brakes for a steep approach with a low sink rate. The OUTLAW’s forward speed can be greatly reduced to a stable deep-brakes configuration.

Center Cell Slat maintains center-span laminar flow- First introduced to BASE canopies on the Atair OSP, the slat system helps to increase airflow over the top surface of the canopy. The Float-Flap system provides a more direct feed to the critical area of the top surface while in deep brakes, and the Outlaw’s single center cell slat encourages flow at the center span. In combination, the Float-Flaps and Center Cell Slat create the best deep-brake behavior of any BASE canopy.

ZP Ellipse at leading edge for heading and glide performance, and longevity- ZP leading edges increase glide performance, opening performance, and sail longevity. The OUTLAW is the only BASE canopy with an ellipsed ZP leading edge, which positions more ZP where it is needed most, at the center span, and just enough outboard ZP to ensure performance. This design encourages priority center-span inflation for heading performance, and the cleanest most efficient airflow possible at center-span for glide and flare performance. A ZP leading edge is especially important in canopies made from ultra-light / low-bulk material, which degrades faster than traditional 0-3cfm cloth. Porosity at the leading edge is a crucial factor for glide and flare performance. Ultra-light cloth is too porous for use at the leading edge of a BASE canopy (or any main parachute, in our opinion).

Staggered Upper Brake Cascade reduces tension knot probability – The OUTLAW’s unique upper brake cascade is constructed without loop to loop junctions. Finger-trapped lines allow a more consistent flex and prevent the acute-angle “kinks” that can lead to tension knots in the brake cascade. The benefits of the OUTLAW’s smooth brake fan are apparent when stowing the lines – the brake line junction curves more smoothly in concert with the rest of your lines, reducing the chances of tension knots. A positive side effect of this design feature is a reduced spacing between upper brake lines, reducing the potential severity of line-over malfunctions. Always use a tailgate, slider-gate, or tail-restricting device in conjunction with packing methods that properly stage tail expansion. Redundancy is the key to reliability.

Advanced Profile and Leading Edge- The OUTLAW’s profile is based on more than a decade of paraglider research and development combined with the BASE experience of the Squirrel team. Our testing has shown that even in the thicker profiles that we use for low aspect ratio BASE canopies, small improvements lead to significant performance differences during all aspects of flight. The OUTLAW profile was chosen for its consistently pitch-stable behavior, dependable glide performance, and excellent slow-speed characteristics.

Varied Crossports enhance inflation characteristics – The OUTLAW features a varied crossport design to maximise spanwise airflow while retaining structural longevity. Unloaded and loaded rib crossports were designed using a load-calculation algorithm. Unloaded ribs feature larger crossport size overall, while loaded rib crossports are concentrated in the ideal locations for load and top-surface cleanliness. This optimization means that The OUTLAW benefits from unsurpassed air circulation inside the canopy, leading to progressive and homogenous openings with a compact and coordinated feel in flight and during flare.

OUTLAW LITEsquirrel_outlawlite_image

The OUTLAW LITE is the lightweight, low-pack-volume version of the OUTLAW. There are many benefits to lightweight cloth in BASE canopy design, and we encourage all jumpers to consider the light version for the following reasons:

  • Reduced canopy inertia during the extraction and expansion phase means better openings, better heading performance.
  • Faster extraction: A lighter parachute can be extracted more efficiently and has an advantage over standard weight canopies in the first seconds of deployment.
  • Easier to pack: Porcher PN9 lies flatter, has less tendency to expand or squirm, and is easier to fold.
  • Easier to carry: Everyone likes arriving at the exit point with a bit more energy.
  • The lower pack volume of PN9 allows a slimmer, more aerodynamic container.

The OUTLAW LITE is not designed especially for alpine or wingsuit applications. We believe the light option should be seriously considered by all jumpers, including those who mainly jump slider down objects. Instead of creating a highly-specialized canopy, our focus was on a new type of versatility made possible by low freefall specific features and reefing devices for terminal openings. The OUTLAW LITE is a user-friendly design that performs well in a vast range of applications for all qualified jumpers. These advances in BASE parachute technology are tangible features that yield real results.

The OUTLAW LITE has all of the same technical features as the standard OUTLAW, and is a versatile design that excels in technical landing areas. Since its release the OUTLAW has become known for excellent deep brake behavior, extremely low forward speeds at opening, and stable characteristics. The OUTLAW design contains real innovations in BASE canopy design that can be seen and experienced:

Durability –Lightweight 0-3cfm cloth has changed sport parachuting. By applying it to certain sections of the canopy, or combining it with a zero-porosity leading edge, a well-designed lightweight canopy offers similar longevity to standard weight options when cared for appropriately. Ultralight cloth is not recommended for jumpers who are frequently landing in sandy, dirty, or brushy locations. If you primarily jump in the US Southwest, for instance, then you will need to take extra care of your canopy. Dirt and sand that works its way into the parachute will accelerate ageing as it grinds into the cloth’s coating. Moisture is also contra-indicated, so if you are planning a bunch of water landings then we don’t recommend the light option.

Price- Lightweight cloth is significantly more expensive than standard weight 0-3cfm, and Porcher Sport offers the highest price material. Due to the volumes at which we purchase cloth in this spec, and the fact that we see it as a real benefit and performance upgrade, we are offer the OUTLAW LITE at virtually the same price as the OUTLAW standard.

Quality – Currently there are four major manufacturers of lightweight 0-3cfm cloth. Lightweight 0-3cfm cloth was originally developed by Porcher Sport of France for use in paragliding reserves. It was adopted by parachute manufacturers soon after and has been used with great success by a variety of brands since then. In cooperation with Ozone paragliders, which purchases this light/low-bulk cloth in large quantities, we have tested material from all major manufacturers. At this time the Porcher PN9’s performance in terms of mechanical stability, porosity, weight, and pack volume, is the best available. Not all “lightweight” cloth is created equal. Before considering a lightweight parachute design, ask the manufacturer what cloth is used. We are continually evaluating cloth options on the market to ensure that we are offering the best.
