I am modifying my RV 7 to a larger 4 inch cooler duct and I want to put in some type of shutter in line . I see Aircraft Spruce sells a TSW shutter with an electric servo as well. Has anyone on the forum ever used this kit or is a there a better inline type available. Thank You

Not sure which one you're talking about as I can't find TSW on Spruce. I installed this one from Vans and a servo which seems to do the job.

I used the controller from Cleveland below with a simple push/pull cable and it has worked great for nearly 4 years.....

TCW, makes one. The backup battery guys. It for a 10 but a 4 inch. They tested to actuator to temps close to 200f.
