Here's my setup for the Pie Servo.
It's not fancy but it gets the job done.
I used a Hitec MG85 servo and a 4-40 linkage to the hinges. The hinges I added a small threaded rod from hinge to hinge and this gave me something to attach the rod too.
The only thing I want to change is the treaded rod, I want to used some smooth rod so the arm does'nt grab the threads as it moves. Also the rod in the hinges has to be free floating or it will bind up the hinges as the move. As you can see in the video, The servo has more than enough power to open/close the pie panel.

Thanks for this post Calvin. The picture helps out quite a bit, I've been wondering how to do this myself and this certainly made it easier.
Nice. Do you remember where you got the linkage pieces from and how much they were? Website link would be good. Thanks in advance.
The linkage was purchased at my local Hobby shop awhile back.
It's used on model airplanes for support.
Sorry I don't have more info but it was bought for another project and wound up on R2.
