Spent a bit of time reorganizing the saw horses in order to see how to fit the tail boom tube to the fuselage as I am waiting on rivets to show up tomorrow so I can finish rigging and installing the RH horizontal stabilizer / elevator.
Ended up swapping the sawhorses from under the fuselage to under the tail boom tube and vice versa. One set are height adjustable whereas the other pair are not, the tail needs to be adjustable.
With a bit of effort, I got the tail to mate up to the fuselage but it would not seat. After a bit of trial and error, I finally pulled the tube out and noticed the fuselage section had welds at 12 o'clock that prevented the tail tube from going all the way in. After conferring with the manual, I found a line that explained this possibility and that I will have to clearance the tube around the welds.
So, I have to figure out where I put my Dremel and I will work on the clearance of that section next.
