Test run not so good:
With the grates flipped so that the air would tend to push them open I ran into some issues.
1. the AC line to its radiator hits the left vanes as they try to open.
2. the distance between the vanes and radiator is very short, aka very little air dispersion over the whole radiator.
What this means, I need to make a way to turn the grates around (like I had them in my first try). This might need a redesign of the actuator location/ mechanism.
