Thank you for enlightening me Gary.
I think I'll be able to work with your eCabs design. My goal with your drawing is not so much to use it to cut from, but rather as a guide to show me how you directed the airflow. I assume once I see it I will better understand how the flapper valve works. Will you send it to me via email, or is there something I need to do?
I'm glad to hear you think parallel is the way to go, that helps reduce the complexity a little.
