User's Manual

The propeller is an old variable pitch propeller. It has only two configurations: low and high pitch. Use low pitch for low speeds: takeoff and landing. Use high pitch for cruise (more than 180 km/h).

Standard procedures

Startup
  1. Battery: On
  2. Magnetos: both
  3. Starter: 5 seconds max
Takeoff
  1. Flaps: 25°
  2. Full power
  3. Lift tail wheel at 100 km/h
  4. Initial climb: 150 km/h
  5. 100 m (300 ft): Flaps: 0°
  6. Climb: 180 km/h
Change pitch
  1. Apply pitch: Off
  2. Select pitch
  3. Apply pitch: On
  4. When the light is off, apply pitch: Off

Remark: there are only two different pitches: low and high. "Slow high" ("grand pas lent") makes just the pitch change more slowly than "high pitch" ("grand pas").

Cruise
  • Propeller Pitch: High
  • 2300 - 2400 rpm, 250 km/h
  • Above 1500 m (4500 ft), mixture in order to maximize rpm.
Landing
  1. Flaps: 65°
  2. Speed: 130 km/h, 140 km/h if wind speed is higher than 10 kt

Emergency procedures

Accidental spin
  • Rudder: in the direction of the spin
  • Elevator: neutral position
  • Ailerons: neutral position, DO NOT USE AILERONS
  • When the spin stops: pull (<3.5g) to raise the plane

Limitations

Remark: since I didn't find any manual, most of speeds are just estimates

  • VNE: 400 km/h (215 kt)
  • VFE: 190 km/h (103 kt)
  • Max positive G: +3.5
  • Max negative G: -1.5
  • Max RPM: 2800
  • Max continuous RPM: 2500 for 5 minutes
