HEATING SYSTEM: The heating system is comprised of the heat exchange section of the exhaust muffler, a shut-off valve mounted on the right forward side of the firewall, a push pull control on the instrument panel, Outlets and flexible ducting connecting the system. OPERATION: Ram air is ducted through an engine baffle inlet and heat exchange section of the exhaust muffler, to the shut-off valve at the firewall. The heated air flows from the shutoff valve into a duct across the aft side of the firewall, where it is distributed into the cabin. The shut-off valve, operated by a push-pull control marked "CABIN HT" located on the instrument panel, regulates the volume of heated air entering the system. Pulling the control full out, supplies maximum flow and pushing control in gradually decreases flow shutting off flow completely when the control is pushed full in. DEFROSTER SYSTEM: The defrosting system is comprised of the duct across the aft side of the firewall, a defroste...

FUEL SYSTEM Fuel is gravity fed from the metal wing tanks, through a shutoff valve and a fuel strainer, to the carburetor. Positive ventilation is provided by a vent line and a check valve assembly located in the left wing tank, a crossover line connecting the two tanks together, and a vented fuel cap on the right hand tank. The vent line from the check valve assembly extends overboard through the lower wing skin adjacent to the left wing strut. A fuel drain is located between the shutoff valve and the strainer Fuel shutoff valve is a two-position ON-OFF valve, located in the floor area between the pilot and copilot seats. The handle is safety wired in the "ON" position with .018" diameter mild steel wire (tag wire), which will break easily if the handle must be turned "OFF" in an emergency. The manufacturer recommends replacement instead of repair or damaged, worn or inoperative valves. FUEL STRAINER: The fuel strainer is mounted at the firewall in the low...

CONTROL SYSTEM AILERON CONTROL SYSTEM : The aileron control system is comprised of push-pull rods, Bellcranks, cables, Pulleys, sprockets and roller chains, all of which link the control wheels to the ailerons. A control "Y" interconnects the control wheels to the aileron cables. CONTROL "Y": The control "Y" transforms rotation of the control wheels into pulling motion on the aileron cables by means of sprockets and chains. The "Y" is pivoted at the lower end to operate the elevator control system. WING FLAP CONTROL SYSTEM : The wing flap control system is comprised of an electric motor and transmission assembly, drive pulleys, push-pull rods, cables and a follow-up control. Power from the motor and transmission assembly is transmitted to the flaps by a system of drive pulleys, cables and push-pull rods. Electrical power to the motor is controlled by two micro switches mounted on a floating arm assembly, by a camming lever and follow-up co...
