Step 4: Installing the Wing Reinforcement Board
❑
Using a modeling knife and a ruler, cut a 1/4" x 7/8" hole,
1-3/16" up from the bottom of the trailing edge reinforcement
board.
☞
This hole will prevent the reinforcement board from
interfering with the aileron torque rods when it is installed.
❑
Remove the protective backing from the trailing edge
reinforcement board.
❑
Carefully apply the reinforcement board to the
top
of the
wing, making sure the board is centered over the centerline of
the wing and the back edge of the board is even with the
trailing edge of the wing.
IMPORTANT
Before installing the trailing edge reinforcement board in the next procedure, make sure that both aileron torque rods are
completely down in the molded grooves.
❑
Flex the ailerons up and down several times to make sure the torque rods are not sticking to the reinforcement board.
❑
Carefully remove the protective backing from the wing reinforcement board.
❑
Carefully apply the reinforcement board to the
top
of
the wing, making sure that it's centered over the wing's
centerline and that the back edge of the reinforcement board
is about 1/8" in front of the trailing edge reinforcement board.
IMPORTANT
It's very important to the integrity of the wing that the reinforcement board be adhered to the wing along its entire
surface.
