The air intake is a great feature of this plane. It and the Super Sabre share a similar squashed intake that reduces the fuselage height a bit since it snakes under the cockpit going aft.
Here are the parts
Of interest is the placement of a shaper disc that fits in the intake. You then drop a long bead of Super Glue around the forward open section making sure not to glue this disc. When the glue dries if forms an almost plastic like shape around the intake preserving the shape of the mouth.
nose section
now assemble the intake to the aircraft 2 forward nose sections
Then insert the shaper disk at the mouth
and add a bit more super glue from behind ( this is only if needed )
once dry, there is an intake upper panel that fits inside.
Glue it in place ( mine was OK, not perfect ).
