The center hatch which covers
the engine is locked by two
piano wires running all the way
from the small hatch at the
nose into the rear hatch which
we permanently glued on in an
earlier stage.
The piano wire runs through
the white 2mm ID plastic
tubing.
It is recomended to glue the
plastic support rails to the
hatches on various points for
support. You do not need to
glue them all the way through.
To allow a smooth opperation
make sure not to bend the pin-
line more then absolutely
necessary. The more it is bend
the harder the pins will slide
throughlater.
The nose hatch needs to be
cut as shown in the rear to give
the clearance for the piano-
pins that hold the center
engine hatch.
