The MK IV “high tech” Yaw String - is the only Yaw Strig with a clear turbulator base. Do not be fooled by imitations. This is not your ordinary yaw string. The clear base raises the synthetic yarn 0.038″ above the canopy eliminating scratches and reducing static charge.

Quiet Vent is installed on MECAPLEX windows with a pop–out scoop. It reduces cockpit vent noise by 10 dba. Air flowing into the sailplane through the side window impacts MECAPLEX scoop components creating turbulence and noise. Quiet Vent produces a smooth airflow transition into the cockpit, avoiding MECAPLEX scoop components, thereby reducing cockpit noise.
