Motor, Esc And Battery Installation - Hangar 9 Twin Otter ARF Assembly Manual

Step 4
Slide the nacelle into place and push it all the way
against the wing. Use low-tack tape if necessary to
hold the nacelle in place while the glue cures.
Hint: Cut a 2 3/4 inch piece of dowel and insert it
between the motor box sides to help the nacelle make
complete contact with the wing ribs.
Step 5
Apply a bead of canopy glue around the perimeter of
the nacelle where it meets the wing surface. Use tape
or weights as necessary to hold the nacelle in contact
with the wing. Use a damp paper towel to clean any
excess glue before it cures.
Step 6
Repeat steps 1 through 5 to install the opposite nacelle.
