The ABS Horizontal Stabilizer tips protrude a bit forward at the very front due to the positive draft angle so we can get them off the mold when formed. This interferes with a good fit. Using a sharpie, mark on the tip where the aluminum skin overlaps, modify the tip as shown in the photo just shy of your mark. Perfect fit!

The Rudder, Elevator, Flaps and Ailerons are easy to set up on flat blocks because of their straight surfaces. The Horizontal Stab is not so easy because of its airfoil shape. Here is a method I have been using that produces consistent results and a very straight Stab. First step is to source 4 aluminum angles of the dimensions shown. Any similar material is suitable.
