Guimbal Cabri G2 — Quick Reference

Engine

• Type: Lycoming O-360-J2A — four cylinder, horizontally opposed, direct drive, air-cooled, carbureted
• Power: 160 HP (5-min takeoff) / 145 HP continuous
• Idle: ~1,000-1,200 RPM per POH

V-speeds

• VNE: 130 kts power on / 110 kts power off (below 3,000 ft Zp). Reduce VNE by 2 kt per 1,000 ft pressure altitude.
• VY (best rate of climb): 50 kts IAS
• Climb speed: 50 kts IAS
• Cruise / max range: 80 kts IAS

Autorotation

• Recommended airspeed: 50 kts IAS (range 30-50 kts)
• Minimum descent rate: 49 kts → ~1,770 fpm
• Best glide: 78 kts IAS

Rotor

• Green arc (rotor RPM): 515-540 RPM
• Three-blade fully articulated main rotor
• Tail rotor: high RPM ratio (~10:1) — vibrations register as high-frequency rather than medium

Hover

• Stabilize at 2 ft skid height for hover-check

Weight & Balance

• Maximum gross weight: 1,543 lb (CG aft limit 75.4 in)
• Minimum weight: 1,036 lb (CG fwd limit 83.5 in)

Note the unusual CG envelope — the forward limit (83.5") is aft of the rear limit (75.4"). The Cabri's CG nomenclature uses a different datum convention than US-built aircraft. Check the POH chart, don't try to memorize the orientation.

Oil

• Type: SAE 15W50 normally; straight mineral for first 50 hours of break-in
• Quantity: 4 qt min, 6 qt max
• Temperature: 245°F max
• Pressure: 115 psi max

Fuel

• Type: AVGAS UL91 or 100LL preferred
• Minimum octane: 98
• Required: Zero alcohol content

Wind limits — initial-experience pilots

Operator-specific guidance often applies — many flight schools impose tighter wind limits during initial 200 hours total / 50 hours in type:

• No flight with surface winds > 25 kts including gusts
• No flight with gust spread > 15 kts

These match the conservative envelope used by Robinson R-22 operations as a useful baseline. POH limits may be wider; defer to operator policy.
