Wing Assembly - Mountain Models DuskStik Builder Manual

Vertical Stabilizer, Rudder, Horizontal Stabilizer, and Elevator Assembly
The tail assemblies are made up from parts found on the 3/32" balsa laser cut sheet. The plans are laid out
on a flat worktable and taped down, and then a sheet of wax paper is laid over the plans. This will protect
the plans from the glue. The pieces of balsa are positioned over the plans. Each joint can be glued by
holding the two pieces in place and applying a drop of thin CA to the joint. In the past, you may have
used pins to hold parts down, but I find this process to be faster and you don't have to worry about the pin
damaging the 1/8" balsa. You do have to worry about keeping your fingers far enough away from the
joints or your fingers will become part of the model.
Fig 5.
1. Tape plans for vertical stabilizer and rudder to a flat building surface, and cover with wax paper.
2. Using the drawing as a guide, glue with thin CA the vertical stabilizer and rudder. When dry,
remove from wax paper and reinforce joints with thick CA. Set aside.
3. Using the drawing as a guide, glue with thin CA the horizontal stabilizer and elevator. When dry,
remove from wax paper and reinforce joints with thick CA. Set aside.

Wing Assembly

Note: The wing can be built as a dihedral or polydihedral, standard 42" or extended 50" wing. There
are two extra ribs on the 3/32" balsa sheet for the extended wing. The standard wing is a good, all
around wing, which can handle small amounts of wind. The extended wing is more suited for thermal
chasing and slower flight but will be more susceptible to gusts. The polydihedral wing is an excellent
wing for beginners. It is very stable and handles slow flight exceptionally well. The dihedral wing
will loop better and is more fun at higher speeds.
Building the extended wing involves adding an additional rib to the end of each wing and moving the
polydihedral break out one rib.
