JFX 2 vs Storm

JYRO JFX 2 · Performance Designs Storm · Canopy explorer

Manufacturer facts side by side, with the source on every row. Nothing on this page says which canopy to choose or what wing loading to fly — that is a conversation for you, your canopy coach and your drop zone.

What differs — read from the data

JFX 2 is made by JYRO; Storm is made by Performance Designs.
Planform: JFX 2 is listed as elliptical; Storm as semi-elliptical.
JFX 2 has 9 cells; Storm has 7 cells.
JFX 2 is cross-braced; Storm is not.
JFX 2 is listed in 69–119 sq ft; Storm in 97–230 sq ft.
The listed size ranges overlap between 97 and 119 sq ft.
The manufacturers publish different systems: Performance Designs lists a maximum exit weight per skill category and size; JYRO lists a recommended wing-loading range and a chart with jump-number bands. They are shown side by side, never translated into each other.

Structural facts only (manufacturer, planform, cells, bracing, sizes, chart system). How each wing flies is described below in the manufacturer's own words; how it flies for you is a question for a canopy coach.

Characteristics (manufacturer keywords)	Predictable, soft crossbraced openings · Light, instinctive harness inputs · Dive longer than the original JFX but not as long as Leia · Slow, predictable, adjustable recovery arc · Immense bottom-end flare Source: JYRO — JFX 2 product page (page modified 2026-09-02) ↗	Soft openings with long snivel · Steep glide · Long recovery arc · Long control range · Powerful bottom-end flare Source: Performance Designs — Storm product page ↗
Opening	Predictable, soft crossbraced openings — 'the ace card of this canopy' (JYRO).	Soft, on heading and very forgiving to minor inconsistencies in body position during deployment; compared to a Spectre, a slightly shorter snivel and ever so slightly quicker inflation.
Recovery arc	Slow, predictable, easily adjustable recovery arc (JYRO).	Long recovery arc (product page); will dive longer and lose more altitude in a turn than a comparable sized Stiletto or Silhouette, but not quite as much as a Sabre2.
Glide	not published	Steep glide (product page); great slow flight glide when the brakes (or rear risers) are applied.
Speed / dive	Dive longer than the original JFX, not as long as Leia (JYRO) — no airspeed figures published.	Flies somewhat similar to the Spectre but has a much larger speed range; in full flight greater speed than the Spectre (qualitative; no figures published).
Flare	Immense bottom-end flare; stalls later (JYRO).	Lower flare point than Silhouette or Stiletto; flare point similar to the Spectre, but quite a bit more powerful; powerful bottom-end flare.
Front risers	Effective; slow the canopy a little before the turn to reduce pressure (JYRO).	Front riser pressure slightly higher than the Spectre, but requires less input to receive the same response.
Rear risers	Light, instinctive, trustworthy (JYRO).	Very maneuverable using the rear risers as a very useful tool in extending the glide or turning with less tail deflection.
Harness response	Light, instinctive, very responsive — can be flown largely on harness (JYRO).	not published
Toggle response	Powerful and responsive at the bottom end (JYRO).	First one half of the toggle stroke seems less responsive than a Silhouette or Stiletto; past that you'll see just how sharp it can turn. Extremely agile in deep brakes.
Loading system	Recommended wing-loading range 1.6–2.2 lb/ft² plus a chart with jump-number bands (below).	Maximum exit weight per PD skill category and size (chart below).
Manufacturer-stated experience requirements	none stated	none stated
Evidence level	B — Manufacturer product information	A — Manufacturer technical documentation

Flight wording is quoted or closely paraphrased from each manufacturer's own documents; where a manufacturer publishes nothing for a row it says "not published". No airspeed figures are published by either manufacturer.

Your wing loading on each size

Exit weight (you + all gear): kg

Enter an exit weight to see exit weight ÷ size for every listed size of both canopies and where each number sits on the manufacturer's own chart.

Wing loading = exit weight (lb) ÷ size (ft²). PD's chart lists the MAXIMUM exit weight per skill category — the category shown is the lowest one whose maximum covers your weight, by PD's own rule. JYRO's range is a manufacturer envelope, not a target. The two systems are never translated into each other.
