2.9 Insert (trial fit) the 5" long 1/4" Wing Dowels in the prepunched holes. Drill out holes with a 1/4" bit if necessary.
Remove the dowels and fuel proof them as you did the PC, with thinned epoxy, and reinstall when dry. Glue the back dowel
in place with epoxy or clear adhesive/sealant. WE DO NOT GLUE THE FRONT DOWEL IN PLACE. THIS WAY IT CAN BE REMOVED TO GIVE
ADDITIONAL CLEARANCE WHEN EXTRACTING THE LOADED PC FROM THE FUSELAGE.
TRIAL FIT THE POWER CARTRIDGE
2.10 If you'd like, you can slide the PC into the rails to see how this works. It should fit snug, but still be able to slide
in. The nose area of the fuselage will require some trimming with a hobby knife at final installation to accommodate your
particular engine, needle valve and muffler. The PC will be moved fore and aft to balance the model when complete, then
held in place with retaining screws for flight.
STABILIZER/ELEVATORS
The Stabilizer and Elevators are a two-piece assembly joined with dowels for stiffeners. Both the stab and the vertical fin
utilize a "living hinge" concept developed for simplicity and strength.
2.11 Locate the stabilizer/elevators and separate the two halves (left & right) with a hobby knife.

HINGE FLUTE
2.12 Locate the flute to be used as a hinge for the elevators. The hinge flute selected should allow both elevators to
move up and down independently (they are later joined with a joiner wire). Once you locate the hinge flute, carefully "slit"
the flute skin on the bottom (undecorated side) of the stabilizer the length of each elevator using a single edge razor or
sharp razor knife. DO NOT "SLIT" THE AIRCORE ALL THE WAY THROUGH! THE TOP "SKIN" SURFACE OF THE HINGE FLUTE IS YOUR HINGE!
Once you slit the flute, use a razor or hobby knife to trim away the excess skin on each side of the slit to the inner wall (see
illustration) to finish out the hinged surface.
2.13 Install 5" X 3/16" diameter dowels and 1.25" X 3/16" diameter dowels in the flutes of the elevators as shown in
the illustration. Using sandpaper, sand "flats" on each side of the dowels so they will not form a protrusion when pushed
into the flutes. Also sand "flats" on the elevator dowels where the elevator joiner wire hole will be drilled to keep your drill
bit from going off-center when drilling later. These dowels provide stiffening in the elevator and are drilled for the elevator
joiner wire.
