Do this to all six flap hinge blocks in the
wing. Repeat this process with a 3/16
bit, a finally with a ¼” bit. This
progressive drilling makes for a cleaner
hole.
The ¼” will allow for the Robart® 3/16”
Hinge Pocket to fit as shown below.
The purpose for the hinge pockets (you
will use them in the flap as well), is to
allow for fine alignment adjustments and
for extending the useable length of the
hinge. This last point is important as the
actual hinge point is set below and
behind the LE of the flap. Temporarily
insert a pocket into each hole.
Insert a hinge into each hinge pocket
located in the wing (not glued in yet!).
Place a 1/8” spacer at the flap root and
hold the flap against the TE of the wing.
Position the point hinges so they are
perpendicular to the wing’s TE and over
the flap’s balsa blocks. Mark on each
flap block both sides of the hinge near
the LE of the block, as shown.
In a similar fashion as you did with the
hinge holes in the wing, use the drill
guide to make progressive holes into the
flap’s blocks. The holes should begin
just behind the flaps 1/8” balsa. Insert
pockets into the flap and then place the
point hinges in the pockets and test the
flaps movement. You can tighten down
the set screws, if needed. The flap
should move effortlessly through full
range.
9. Trace the flap’s LE radii below onto a
piece of paper and transfer the LE
shape onto the root and tip ends. Note
that you will be removing some of the
EPP at the top surface. Draw a line on
the top flap surface connecting the TE of
the upper curvature from root to tip.
