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.

afety and operational qualities

*The Silent Club has light ailerons, light elevator, along with a generous rudder. The roll rate is quick due to of the lively feel of the ailerons.
*Stall is predictable and recovery is quite simple. In level flight as airspeed is reduced when approaching the stall speed the sailplane vibrates 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.
