Both the fore and aft fuselage doublers are installed using pin
registration to assure that all notches are correctly positioned.
Take care to assure that the left and right side parts are cor-
rectly paired up as they are not interchangeable. 1.5° of left
and down thrust is built into the firewall.

label indicating the left side.

tom. Use the a square to assure that they are at 90º to the
fuselage bottom. Note that the firewall will be installed
last.

7 Place the sides in position and assure that all notches and
tabs are fully nested. Then beginning at the front, apply
thin CA to all formers and the fuselage/bottom corners
while pressing firmly together.

Install the firewall and line the sides with ¼: triangle
stock for extra strength.

Install two 1/8” square balsa braces on both sides of F-2
and one in the aft end just ahead of F-11 in the notches
provided.

13 If you are going to cover the model you may want to
install the pylon and the vertical fin to the fuselage after
covering, if not you can install the pylon at this time.
The fuselage assembly nearing completion. The 1/4” triangle
stock between the firewall and the fuselage sides will be in
-
stalled next and then the top can be installed. Check frequent-
ly for straitness and twist in the fuselage while assembling it.
Keep the bottom flat on the building table when gluing up the
sides and bottom.

4 The hatch on the bottom of the fuselage is optional how-
ever the hatch frame must be installed in either case. The
corners of the hatch opening have been cut so you can
use these as your guide to open up the hatch area. Use the
pin registration method to install the hatch frame HA-

INNER WING PANEL ASSEMBLY
We will begin by assembling the inner wing panel first. Consider any wash in or wash out you want to
introduce into the structure. Excellent results have been obtained with 1/8” of wash in added to the inner
panel. This is easily accomplished by shimming up the leading edge with some 1/8” scrap balsa at W-6.
£
1 The wing is built over the plans in the conventional man-
ner. Start by pinning the trailing edge W-15 into position
on the plans.
Wing assembly underway, note the shim stock under W-1 and
W-2.
£
2 The wing spar is a true I-Beam comprised of two sheer
webs (top and Bottom) and two ply spar flanges. Locate
the bottom spar web (SWB) and slide each rib into the
appropriate notch in it.
