INSTALL THE FORWARD WING FAIRING
❏
1. Install the wing onto the fuse with wax paper
or Plan Protector under the front portion of the
wing saddle.
❏
2. Check the fit of the die-cut 1/8" plywood
F-3C. Trim the height of F-3C until it is undersized
compared to the chin block height by 3/32". This
will leave room for sheeting.
❏
3. Glue F-3C to the wing with medium CA.
❏
4. Cut the 3/32" balsa sheeting for the fairing
using the pattern on the fuse plan. Test fit and trim
the sheet until it fits well. For best results, sand the
sheet thinner toward its aft end.
❏
5. Glue the fairing in place. Blend the fairing
into the chin block. Use balsa filler to blend the
fairing into the wing.
❏
6. With the bottom cowl installed, use a razor
plane and sanding bar to blend the chin block to
the cowl.
FIT THE SCOOP
❏
1. Place the die-cut plywood scoop support
(SS) in position on the bottom of the wing, but do
not glue it yet.
❏
2. Trim the left and right scoop halves along
the molded cut lines. Notice that the left scoop half
has a tab along the joint that the right scoop half
fits over.
❏
3. Use your bar sander to carefully true the
edge of the overlap so when you glue them
together the seam will be as small and straight as
possible. Thoroughly roughen all areas that are to
be glued. Also, roughen the area inside the scoop
along the joint.
❏
4. Test fit the radiator halves together and
make adjustments as necessary.
❏
5. Join the scoop halves together with thin CA.
