You got it..... Pull-pull on elevators works just fine. Have done it for more than 20 years that way

Frank I. gave very good info. I would add that as long as you place the servo output arm in the center of the fuse, both latterally and vertically, it will matter very little whether the servo is upright or sideways. Upright is a simpler set-up but sideways is a very slightly more accurate set-up....but hardly enough difference to notice.
