The Silent Club is a single seater sailplane of Italian manufacture. It is of the FAI type Ultralight Class glider. It is sold by Alisport ready-to-fly or kit-built as pure glider or self-launching glider. The self-launching version is fitted with a single-blade propeller belt-driven by a two-stroke engine.

Design and construction

  • The fuselage is carbon and glass fiber composite with epoxy resin.
  • The wings spans 12 meters without winglets.
  • The flaperons stretch for 10.0 meters of the full wingspan.
  • Schempp-Hirth-type spoilers extend on the upper wing surface only.
  • Fixed or retractable main wheel behind the pilot, with shock absorber and drum brake activated via spoiler control lever aft travel.

Safety and operational qualities

  • The Silent Club has light ailerons, light elevator, generous rudder. The roll rate is quick because of the lively feel of the ailerons.
  • Stall is predictable and recovery simple. In level flight as airspeed is reduced when approaching the stall speed the sailplane vibrate a little, at this point decreasing the angle of attack results in airspeed increase and normal flight resume, from a climbing attitude the sailplane stall decisively, the nose pitch down gently and recovery is easy with stick forward.
  • Spin entry is obvious and recovered with rudder and stick.

The Silent Club version has 12 meter wingspan.
The Silent 2 version has 13 meter wingspan.
