Between the 6th and 9th, I made some back plates for where the cable exits the fuselage, and mounted the rudder so I could get the exit points just right. I also determined that the rudder travel was not reaching a full 30 deg so that will require adjustment. I also experimented with various means of filling in gaps between the fabric and fuselage members in the interior, but ended up removing the patches because it looked worse with them on. I went around the fuselage with a soldering iron to make holes for screws, bolts, cable exits, drain holes, pulleys, etc.
