RE: Charlie Kellogg's TBM Avenger Build
Yea that's him.
For the servocity stuff I was going to use a metal chain about 6 inches long. The nice thing about using that set up is you do not have to worry about what size sprocket you use as it is true around the center just as the pulley on the rudder end. It will act as a sort of gear reduction though. If the sprocket is half the size of the rudder pulley then it would be a 2 to 1 reduction. Not that it will put more force on, but the smaller sprocket would have to move twice as far to move the pulley the same amount. To connect it to the pull pull, I had really not thought that far, but may have used a loop of cable through the chain hole and then run the cable through the pull pull adjusters. Just a thought. Sevrvo city may even have something for just that application.
