The first fuselage frame
has been assembled, and assembly of the second side is in progress on
top of it with clear wrap between the sides.
Leave the lower
longeron long in front. Alignment of the front vertical is
important as
it sets the angle of the firewall.
The upper frame part
overhangs the front vertical as well, by 3/32".
Fitting the short length of 3/16" square
balsa that spaces the aft fuselage. It is recessed forward 3/32"
to allow the fit of the fin spar aft of it.
Joining the fuselage at the aft end.
Once the back end is tacked together,
fit the firewall.
