HOW TO CUT COVERING FROM BALSA Use a soldering iron to cut the covering from the stab. The tip of the soldering iron doesn’t have to be sharp, but a fine tip does work best. Allow the iron to heat fully.

Use a straightedge to guide the soldering iron at a rate that will just melt the covering and not burn into the wood. The hotter the soldering iron, the faster it must travel to melt a fine cut. Peel off the covering.

5. Before gluing the stab into position in the fuselage, check the fit of the elevator joiner wire by inserting it into the holes in the leading edge of the elevators. Lay the elevators on a flat work surface and confirm that they both lay flat. If not, remove the wire from the elevators and use pliers to bend or “tweak” it until they do. Do not attempt to bend the joiner wire while it is installed in the elevators!

6. Insert the elevator joiner wire into the aft end of the stab slot. Insert the stab into the slot and center it left and right. Measure from the wing tips to the stab tips and make those distances equal. Confirm that the stab and wing are still parallel. A weight can be added to one side of the stab to make any small corrections. When satisfied, wick thin CA along the edges where the stab meets the fuselage. When the CA has dried, confirm that the stab is thoroughly glued to the fuselage. Note: epoxy can also be used in this step.

DRILL A 5/64" [2mm] HOLE, 3/8" [9.5mm] DEEP, IN CENTER OF HINGE SLOT

CUT THE COVERING AWAY FROM THE SLOT

7. Drill a 5/64" [2mm] hole 3/8" [9.5mm] deep into the center of each hinge slot in the elevator halves and stab. Trim the covering away from each hinge slot to ensure that the hinges will be properly glued in place.
