I have been toying with that idea for a long time,
Tracey.  The old Mack truck I owned had a mechanism
that would open shutters when the radiator got warm.
'Course it was broken (I did say it was an OLD Mack,
didn't I?)  Does anyone know of an example of using
this same technique to control a cowl flap?  The
closest I've seen is a controller off a VW that
follows along the same concept.

 

Nothing wrong with doing an automated system but I was thinking in terms of a manually controlled cowl flap.  Better to get the thing flying then add the wiz-bang stuff later.
