My Posts This: Topic Forum | Firstly check the elevator arm (between the frames) has the set screw located correctly onto the flat in the spindle that it is on (dont just tighten it, check it is on the flat)
Make sure your links are free (binding can stop it returning to zero)
Cheap servos may have a high deadband (not accurate) which will also stop them returning to centre.
