JYRO Leia · JYRO Petra · Canopy explorer
What differs — read from the data
- Leia and Petra are both made by JYRO.
- Planform: both are listed as elliptical.
- Both have 7 cells.
- Both are cross-braced.
- Leia is listed in 59–99 sq ft; Petra in 55–89 sq ft.
- The listed size ranges overlap between 59 and 89 sq ft.
- JYRO's recommended wing-loading range: Leia 2.2–2.8 lb/sq ft, Petra 2.5–3.0+ lb/sq ft. A range is a manufacturer envelope, not a target.
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.

| Opening | Soft and well-staged with excellent heading control (JYRO). | Firm but not hard; brisk when terminal (JYRO). |
| Recovery arc | Very long recovery arc; requires large input to recover from the dive (JYRO). | Long recovery — requires pilot input for level flight (JYRO). |
| Glide | not published | High maximal glide ratio (JYRO). |
| Speed / dive | Dives fast, sleek and steep (JYRO) — no airspeed figures published. | Very long, steep dive; 'the most high performance wing you can buy' (JYRO) — no airspeed figures published. |
| Flare | Massive range, very powerful flare, light toggle pressure (JYRO). | Very powerful and responsive (JYRO). |
| Front risers | Light, excellent feedback (JYRO). | Very light (JYRO). |
| Rear risers | Powerful, plenty of warning before stalling (JYRO). | Range, range and more range; very responsive (JYRO). |
| Harness response | Very sensitive on the roll axis and all inputs (JYRO). | Highly sensitive (JYRO). |
| Toggle response | Highly responsive, light pressure; high stall point (JYRO). | Highly sensitive; high-speed stalls possible with abrupt inputs (JYRO). |
| Loading system | Recommended wing-loading range 2.2–2.8 lb/ft² plus a chart with jump-number bands (below). | Recommended wing-loading range 2.5–3.0+ lb/ft² plus a chart with jump-number bands (below). |

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.
