• Fuselage
• Horizontal stabilizer with elevator
• Vertical stabilizer with rudder • Hobby knife • Rubbing alcohol
• Ruler • Paper towels
• Felt tipped pen • Epoxy brush
• Masking tape • Mixing stick
• Pencil • Sanding stick (medium)
• 30-minute epoxy • 90-degree triangle
Step 1. On the rear of the fuselage, a slot is cut for the
vertical stabilizer and a platform is provided for mounting the
horizontal stabilizer. You will need to also locate the pushrod
exit for the rudder, which is on the top left of the slot for the
vertical stabilizer. The covering may cover this opening. If so,
use a sharp hobby knife to cut away the covering over the
pushrod exit.
Step 2. We will mount the horizontal stabilizer first. Remove
the elevator; it will be reattached when you hinge the control
surfaces later. Note that the slot in the fuselage runs from the top
of the fuselage back into the balsa platform that doesn’t have any
covering applied. Trial fit the horizontal stabilizer to the platform
as shown, aligning the slot in the leading edge of the horizontal
stabilizer to that in the fuselage top/platform as shown below.
Step 3. Holding the horizontal stabilizer in place, check to see
that the slots are aligned.
Step 4. With the fuselage, wing and horizontal stabilizer
resting on a flat surface, align the horizontal stabilizer by
measuring from fixed points on the wing to the outside of the
trailing edge tip of the horizontal stabilizer as shown in the
illustration. Be sure that the leading edge of the horizontal
stabilizer stays aligned with the slot in the fuselage top.
Step 5. Use a felt tipped pen or pencil to mark the bottom of
the horizontal stabilizer where it comes into contact with the
sides of the fuselage. The mark will make a slight indentation in
the covering.
