22. Glue in place the 1/16" plywood tail wheel wire support as shown below.
23. Install the Red pushrod housing through the holes in the aft 3 formers. They should come
forward of the front former by 1/8". Secure them with thin CA and then trim them flush with
the fuselage sides where they exit in the rear.
24. Sand the forward part of the 1/8" balsa part, just aft of the rear former so it is flush with the
fuselage sides, as shown in the top right image.
25. Sand the front and rear bottom corners of the fuselage, round the top rear center, and round
the top of the fuselage sides where they meet the top rear deck. Test fit your canopy and
cowling to make sure you have rounded the corners enough for the parts to fit properly. Fill
any voids with lightweight filler and then lightly sand the entire fuselage with 320 grit and
then 400 grit sandpaper.
