Place servo into the correct location, set the length of the clevis rod, attach to trim tab, and begin testing and adjustment to get to best travel distance for up and down deflection targeted in the plans. This servo Zenith shipped does not have quite the range specified in the plans though. I'm within 5 degrees up and 8 down. I'll enter exact numbers in a later entry. Run the wire out to the center section of the elevator. Link to test on youtube: https://youtu.be/F_ooA6mKN88
