As a hint afterwards, if you are using rubber bands to secure the wing to the fuselage, I use a very thin piece (line 1/16 inch wide) of black covering (contrasting) to form a line along the centerline of the top of the fuselage with the wing perfectly centered. I iron that on and put another layer of clear over that so it stays put, then cut it along the fuselage where the TE and LE meet. Then re-iron the covering strip so that it won't lift in flight. Use this line to align the wing to the fuselage then secure with your rubber bands. Then after you are done, and you have followed all the above instructions on the horizontal stab installation, you can be assured that all is properly aligned and good and straight. At least it will look good.. it will fly just fine no matter.
