Even the Edges:
❏
6. Using a flat sanding block or similar tool, lightly
sand the wing roots to remove any irregularities. Do not
sand off too much as the dihedral angle could be
altered.
Install the Front Root Ribs:
❏
7. Locate the two 1/8" (3mm) front root ribs. Position
the rib so the tab is on the top of the wing. The aileron
torque rod is also located on the top of the wing, which
can be used as a reference. Align the rear edge of the
rib flush with the front edge of the joiner pocket. It
should also follow the contour of the bottom of the wing.
Use 1/4 oz. (7.5ml) of 6-minute epoxy to glue the rib in
position. Use masking tape to hold the rib securely to
the wing until the epoxy has fully cured.
Install the Rear Root Ribs:
❏
8. Locate the two 1/8" (3mm) rear root ribs. Position
the rib with the front edge flush with the aft edge of the
joiner pocket. The rib should follow the contour of the
wing airfoil when positioned correctly. Once satisfied
with the fit, use 6-minute epoxy to attach the rib to the
wing. Use masking tape to hold the rib securely to the
wing until the epoxy has fully cured.
Mark the Wing Joiner Pocket:
❏
9. Lay the wing halves on the work surface with the
aileron torque rods facing upwards. Place a mark at the
aft edge of the wing joiner pocket using a felt-tip pen.
This line will aid in positioning the aileron servo tray.
Position the Aileron Servo Tray:
❏
10. Locate one of the 1/8" (3mm) plywood servo
trays. Position the servo tray so the front edge rests at
the line drawn locating the aft edge of the joiner pocket.
Using a felt-tip marker, mark the position for the front
and rear of the opening in the servo tray.
Mark the Aileron Servo Location:
❏
11. Measure in 3/8" (10mm) from the edge of the root
ribs and draw a line connecting the front and rear lines
