Re-balance Using Tungsten Rod Left Side of VS Bonded to Aircraft. Another thing to consider is a way to close the gap between the top of the HS and the cutout for the HS that you make in the left VS. Ours varied from 0.3 to 0.6". We made a capstrip (a la the old days before fastbuilds!!) on the inside of the VS. We laid up a 2 BID on the inside of VS itself and gently bent it to about 90 degrees toward the centerline of the fuselage. We then set it into position and clecoed it in place on the fuselage. Of course, there was package tape laid down on the HS to release the cap when it cured. We then teased the strip into place from the outside to make a decent 90 degree turn and lay (sag) down on to the HS. All of the strip is on the inside of the VS. When we closed out the left VS, we simply removed the tape, sanded the HS, put a thin coat of flox on the bottom of the cap, floxed up the other areas and put the left VS into place per normal. This added the extra strength of a 2 BID to the left VS-HS joint. The right skin got it because the area was open and accessible. In the manual, it is left off the left side for obvious reasons - you can't get to it. Another benefit to having it is that it forms a dam for adding a good flox bead later to fill the HS-VS gap. When that dries, you add a micro fillet to the area and lay up the BID over the fillet. Rudder Closeout Rudder Closeout Rudder Fitting_1: This is the firsrt of 6 photos of fitting the rudder to the VS. The pictures are annotated to show that the process was complicated by two hinge mis-alignments on the fastbuild tail and the imperfections of the rudder cuff - namely the excessive width where the cuff fits into the TE well of the VS. Rudder Fitting_2: The fitting process was also hindered by a very sketchy set of instructions in the last section of the fast-build tail supplement. Ron Raby, Bryan Burr, Mike Easley, Mike Salzman, Drew Dickinson and especially Tim Ong filled in the gaps. As always, Steve Richards' web site had good advice on the subject. Thanks, guys!
