Step 2: inStallinG the horiZontal StaBiliZer
❑ Apply a generous amount of 30 minute epoxy to the gluing surfaces of the stabilizer, then push the stabilizer into place and realign
it, double-checking all of your measurements once more before the epoxy sets up.
❑ After the epoxy has fully cured, look closely at the glue joint. If there are any gaps between the stabilizer and the fuselage, fill
them, using 30 minute epoxy for added strength.
Step 3: aliGninG and inStallinG the VertiCal StaBiliZer
❑ Remove the rudder from the stabilizer and set it aside for now.
❑ Once you're satisfied with the alignment, draw a line on each side of
the stabilizer where it meets the fuselage. Do this on both the top and the
bottom.
❑ Remove the stabilizer from the fuselage, then carefully cut away the
covering material from inside the lines you drew. Remove the covering
material from both the top and the bottom of the stabilizer.
❑ As you did with the wing, use a heat-sealing iron to adhere the covering
material down where you cut it.
❑ Slide the elevator into the stabilizer mounting slot, making sure that the
top of the elevator is toward the top of the fuselage.
IMPORTANT You must slide the elevator into the stabilizer mounting slot
before installing the stabilizer. If you don't, it will be impossible to install
the elevator after the stabilizer is installed.
❑ Apply a strip of masking tape to the top and bottom of one half of the
stabilizer and to the top and bottom of one side of the stabilizer mounting slot.
❑ Partially slide the stabilizer into the stabilizer mounting slot.
❑ Push the stabilizer down into the mounting slot in the fuselage. To align
it properly, the stabilizer should be pushed down firmly and the trailing edge
of the stabilizer should be even with the back edge of the fuselage.
