JYRO Safire 4 · Performance Designs Valkyrie · Canopy explorer
What differs — read from the data
- Safire 4 is made by JYRO; Valkyrie is made by Performance Designs.
- Planform: Safire 4 is listed as semi-elliptical; Valkyrie as elliptical.
- Safire 4 has 9 cells; Valkyrie has 7 cells.
- Valkyrie is cross-braced; Safire 4 is not.
- Safire 4 is listed in 109–189 sq ft; Valkyrie in 67–111 sq ft.
- The listed size ranges overlap between 109 and 111 sq ft.
- Published aspect ratio: Safire 4 2.55, Valkyrie 2.84.
- 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) | Smooth, stable, on-heading openings · Quick, clean recovery from dives and turns · Powerful progressive flare · Front risers optional at lighter loadings Source: JYRO — Safire 4 product page (page modified 2026-09-02) ↗ | NOT intended as a first cross-braced canopy · Highly responsive to all inputs · Powerful rear riser performance · Great stopping power/shut down · Smooth openings Source: Performance Designs — Valkyrie product page ↗ |
| Opening | Soft, progressive snivel; increased heading reliability; bow-tie bridle balances deployment (JYRO). | Openings smooth, well-staged and with less tendency to search for a heading during inflation. |
| Recovery arc | Recovery from dives and turns is quick and clean (JYRO). | not published |
| Glide | Glide ratio ~2.8; mini ribs boost glide; long straight glide on rears (JYRO). | Very efficient in converting speed into lift; even better than a Comp Velocity at getting you back from long spots. |
| Speed / dive | 'Not trying to be a swoop machine' (JYRO) — no airspeed figures published. | Higher speeds in a dive (qualitative; no figures published). |
| Flare | More powerful, progressive flare; more range (JYRO). | Highly responsive to toggle input and has a powerful flare; stopping power is impressive. |
| Front risers | Accessible and easy to manage; pressure similar to the Safire 3 (JYRO). | Front riser pressure slightly higher than a Comp Velocity, but it wants to rotate, and rotate fast; potential for faster and more powerful turns. |
| Rear risers | Long glide, responds to small deliberate inputs (JYRO). | More power and a wider range on rears than on the Comp Velocity. |
| Harness response | Responds to intentional weight shift; not hyper-reactive (JYRO). | Much more sensitive to harness input than a Comp Velocity; rolls into turns almost effortlessly. |
| Toggle response | Responsive without being twitchy (JYRO). | Highly responsive to toggle input. |
| Loading system | Recommended wing-loading range 1.0–1.6 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
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.
