Chuck has been working on the cabin heat and carb heat boxes. He had to completely fabricate an original design in order to accomodate the engine ring and cowling. Several templates and configurations took up most of thetime. He had a box from a Cessne 150 to get the ideas on what and how to make them. He decided to place the intake on the side cowls with a filter holder streaming to the boxes. These turned out grea. He also determined the size of the opening necessary to provide the proper amount of airflow.
