This kit provides all the necessary parts and hardware for installing pilot-
and passenger-side cabin air vents. The system draws fresh air into the
cabin through two small but very effective NACA-style scoops on the
fuselage sides. Airflow can be controlled by the pilot and passenger using
two adjustable eyeball ventilators. These ventilators are oversized to
provide ample airflow in hot climates, even at the slower end of the
GlaStar / Sportsman's wide performance envelope.
The cabin air vent system can be installed in a GlaStar / Sportsman at any
stage of completion, but it is most easily accomplished immediately after
the fiberglass fuselage shells have been bonded together and fastened to
the welded steel-tube cage structure.
