Leia vs Storm
JYRO Leia · Performance Designs Storm · Canopy explorer
What differs — read from the data
- Leia is made by JYRO; Storm is made by Performance Designs.
- Planform: Leia is listed as elliptical; Storm as semi-elliptical.
- Both have 7 cells.
- Leia is cross-braced; Storm is not.
- Leia is listed in 59–99 sq ft; Storm in 97–230 sq ft.
- The listed size ranges overlap between 97 and 99 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) | Soft, well-staged openings · Very sensitive on roll axis and all inputs · Very long recovery arc requiring large input to recover · High stall point Source: JYRO — Leia 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 | Soft and well-staged with excellent heading control (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 | Very long recovery arc; requires large input to recover from the dive (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 | Dives fast, sleek and steep (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 | Massive range, very powerful flare, light toggle pressure (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 | Light, excellent feedback (JYRO). | Front riser pressure slightly higher than the Spectre, but requires less input to receive the same response. |
| Rear risers | Powerful, plenty of warning before stalling (JYRO). | Very maneuverable using the rear risers as a very useful tool in extending the glide or turning with less tail deflection. |
| Harness response | Very sensitive on the roll axis and all inputs (JYRO). | not published |
| Toggle response | Highly responsive, light pressure; high stall point (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 2.2–2.8 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 |
| 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
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.
