Petra vs Stiletto

JYRO Petra · Performance Designs Stiletto · 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

Petra is made by JYRO; Stiletto is made by Performance Designs.
Planform: both are listed as elliptical.
Petra has 7 cells; Stiletto has 9 cells.
Petra is cross-braced; Stiletto is not.
Petra is listed in 55–89 sq ft; Stiletto in 89–190 sq ft.
The listed size ranges overlap between 89 and 89 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.

Designed for (manufacturer wording)	Experienced competitive canopy pilots with thousands of jumps on small, highly loaded crossbraced canopies (competition-specific) Source: JYRO — Petra product page (page modified 2026-09-15) ↗	Intermediate to Experienced jumpers Getting back from long spots Individuals looking for a fun-to-fly canopy with responsive handling Source: Performance Designs — Stiletto product page ↗
Characteristics (manufacturer keywords)	Firm but not hard openings · Highly sensitive toggles and harness · Very long, steep dive · Long recovery requiring pilot input for level flight · High-speed stalls possible with abrupt inputs Source: JYRO — Petra product page (page modified 2026-09-15) ↗	Flat glide · Short recovery arc · Extremely responsive toggle input Source: Performance Designs — Stiletto product page ↗
Opening	Firm but not hard; brisk when terminal (JYRO).	When propacked, the canopy opens very soft, and somewhat snively. It is somewhat sensitive to body position during inflation, but opens generally on heading.
Recovery arc	Long recovery — requires pilot input for level flight (JYRO).	Short recovery arc (product page). FC: the Stiletto tends to stay in a steep dive for a long time after several high speed turns.
Glide	High maximal glide ratio (JYRO).	Slightly flatter glide angle at full glide than the Sabre; flight in brakes is a fairly slow, very floaty, flat glide.
Speed / dive	Very long, steep dive; 'the most high performance wing you can buy' (JYRO) — no airspeed figures published.	Slightly faster than a Sabre (qualitative only; no airspeed figures published).
Flare	Very powerful and responsive (JYRO).	Less forgiving of overflaring, since its stall is sharper (than Sabre); slightly shorter control range than a Sabre.
Front risers	Very light (JYRO).	Tends to front riser to a higher airspeed, but not at quite as steep an angle as a Sabre; slightly slower turn rate on front risers, but airspeed and rate of descent build up faster.
Rear risers	Range, range and more range; very responsive (JYRO).	not published
Harness response	Highly sensitive (JYRO).	Very responsive to harness movements during deployment.
Toggle response	Highly sensitive; high-speed stalls possible with abrupt inputs (JYRO).	Rolls into a toggle turn much faster than a Sabre; continues to turn as it slowly rolls out of a fast turn.
Loading system	Recommended wing-loading range 2.5–3.0+ 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	700+ jumps at WL 2.2 or above 250+ jumps in the last 12 months Reference from a respected coach/swooper or Petra/Peregrine pilot Competed at least once in the last 12 months (or 3+ Open competitions in the last 3 years)	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.
