Fred, you are absolutely correct in your statement. I saw this when I originally put the fuse together. I took a long time looking at the side view for formers F5 and F7 as they were to be put into the fusealage during the build process. If you look on the plans and at the F7 drawing, it does show the hole on the left side to be higher than the one on the right. However, if you look at the side view of the plans, the left pushrod (rudder) goes through the lower hole on the left side of the aircraft exiting out the lower hole in the rear. Conversely, the elevator pushrod sleeve exits the upper hole in the rear on the right side of the fuse, but by the drawing of the former would go through the lower of the two holes. In my thought process, I considered that the two sleeves would cross over each other as they traversed to the back of the fuse, but the side drawing clearly shows the pushrods travelling parallel to each other. I even tried looking at the top view of the fuse to see if I could tell from that, but the plans of the top view don't show the pushrod configuration. I will admit that I pondered this one for quite a while.
Finally, I looked at the bracing on former F5 (on the side fuselage view) and saw that the brace is on the forward side of the former toward the servo bay. It then goes toward the rear of the fuselage exiting out the bottom slot and through the hole in F7 which is lower than the one on the right side. Since the pushrod sleeves never cross over, the F5 former has the brace on the front side of the former and the sleeve goes through the lower hole for the rudder on the left side of former F7, I concluded that the drawings of the formers from straight on are reversed, if only for the former F7. I hope this makes sense.... Like I said it took quite a while for me to make the decision on which way to install the former (F7) in the fuselage, but I finally opted to believe the side view of the plans and not the former view.
Soooo...you are paritially right... The former in my plane is reversed from the former view on the plans, but is in the correct position from the fuse side view on the plans. You are right though....it won't make much difference either way  BTW: In my past life, I had some time at the drafting table and my conclusion is that either the side view of the plane is wrong, or the straigh on view of the former is wrong....I opted to go with what the fuselage side view shows...

... What I ended up doing was measuring to the center of the top spar and bottom spar, lining up the dihedral support block and tracing the outline of the block so I would know where to make my cuts. I was at first concerned that there really isn't any side to side support for the dihedral block, but with the two wings up against the root ribs, this is a minor need. I just made sure I had plenty of 30 minute epoxy on both the top and bottom spars before I did the final gluing.
