Currently fitting my VS to the fuselage.
1. I've bolted the rear spar to the rear elevator stop the correct vertical distance from the bottom rudder hinge bracket to the top of the longeron. However, I cannot determine (from the plans or dwgs) the proper vertical position of the forward VS spar where it meets the bracket bolted to the HS. If you look in the picture below, you'll note that the forward spar is as far down as I can put it without the bracket trying to overlap the VS rib flange. It fits well enough where it is at, but the VS rear spar flexes enough that I could lift it up or push down the VS forward spar a little in either direction if I wanted. Since the plans called for trimming the bottom of the VS spar, I'm surprised the spar is as high off the HS spar as it is. Am I missing some callout on the plans? How do I determine where it should fit?
2. Also, am I correct in assuming that if I center the bracket in the VS spar web then I will have the correct offset on my VS? Is there some other correct way for determining the offset (aside from the extra washers that I will be putting on the rear spar)?
Thanks.
