Brief Description: Making cabin return air fir heater
It took sometime to cut and shape the foam to what I needed for the 3” air return for the heater. I then duct tapped and got it ready for 3 bids. I need to make a removable section on the NACA heater cooler intake to stop the air from entering the cabin through the return hole once it is made. I will also make a cover to stop any air from coming in from the outside to have cabin air recirculate from cabin though heater and back to cabin. This will keep us warm in the cooler flying times.
