Wing Assembly - Mountain Models ParkJet Build Manual

• Heat shrink can be heated with a soldering iron or, if you dare, with a lighter. Pay close attention
to what is near the heat shrink when you are heating it.
• You really need the sealing iron (Also called a hobby iron). You will find putting on the covering
so much easier. They are reasonably inexpensive and invaluable.
• The parts are held into the sheets by retaining gaps. When you break a part loose, you should
lightly sand the nubs left by the gaps down.
Assembling the Tail
1. Lay down some wax paper on a flat work area.
2. Remove the tail parts from the 3/32" balsa sheets.
3. Carefully holding the pieces together so that you don't glue yourself to the model, flow some thin
CA into the joints.
4. Glue the 1/64" plywood doublers to the rudder and elevator halves using thin CA
5. Flow some thin CA into the elevator joiner rod openings to harden the elevator in that area.
6. Sand the tail surfaces smooth and round the edges.
7. Cover the tail surfaces with the supplied Doculam or a lightweight covering such as Solite. See
the wing covering section for covering tips.

Wing Assembly

Note: It is very easy to make two wings of one side, i.e., two right wings. This is a bad thing.
! Tape a sheet of wax paper over the plans to protect the plans and to prevent glue from sticking to
them.
! Remove the two vertical spars from the 1/16" balsa sheet. You will note that they fit together with
a V joint to form the center wing. Be very careful to make a left and a right wing. It doesn't
matter which vertical spar forms the left or right side.
! Slide the ribs into the vertical spars. The largest rib goes next to the V. Do not glue yet.
! The four spar caps are identical except for the Vs in the center. Take special care to use two of the
same type (V pointing out) on the same side of the wing.
