Like the Oil Cooler inlet damper, I was going to control the damper (or diverter) for the outlet to allow the heated air to dump overboard or into the cabin.  I had the servo and servo controller all set. But I couldn’t get a good mount for the servo and the damper.

I tried different size gears but the location and orientation of the damper prevented me from finding the correct position for the servo.

In the end, I had to fall back to the old standby of using a cable from the cabin.

I took the arm that I had originally made and put a cable stop on it.

The I ran the cable from the copilot side of the keel just under the instrument panel, through the canard bulkhead, up, over and down to the outlet damper.

I oriented the cable so that when the control is pushed in, it will direct the heated air overboard. When you pull it, the air will be directed into the cabin.

Here’s the control end of the cable.

Now that I’m looking at this, I think that I’ll remove and paint it with the interior paint that I’ve been using.
