Worked on mounting the horizontal stab and the rudder today. Got the stab on the fuselage, attached the supports but haven't done the adjusting to verify the horizontal is perpendicular to the vertical stab. Fitted and drilled the front slide blocks. Attached the rudder and adjusted the attachment points so that the proper gap clearances of 1 1/2 inches on the top and 2 5/16 inches at the bottom between the rudder and the vertical stab. Most definitely had to run a tap through the threaded attachment points on the vertical stab to get the bearings to thread in far enough to set the proper gap.
