Instruction manual

❍ 9. Remove the stab from the fuselage. Use a sharp #11

hobby knife, or refer to the Expert Tip on page 10, to cut

the covering from the stab 1/16” [1.6mm] inside the lines

you marked on the top and bottom of the stab. Do not

remove the covering from the trailing edge of the stab. Use

care to cut only into the covering and not into the wood.

Cutting into the balsa will weaken the structure.

❍ 10. Note: If you like you may remove the rudder and

elevator from the fin and stab for these steps. We will glue

them into place later.

Fit the fin into the fuselage and mark the location of the

fuselage onto the fin with a felt tip pin. Also mark the

location of the fin on top of the fuselage. Using the same

method as with the stab, cut the covering material from the

marks on the bottom of the fin and the top of the fuselage.

11. Apply 30-minute epoxy to all joining surfaces of the

stab. Slide the stab into position. Wipe away residual

epoxy with a tissue dampened with rubbing/denatured

alcohol. If the stab required a weight on one side or the

other to align it with the wing, position the weight. Use the

pin and string to confirm stab alignment. Do not disturb the

model until the epoxy has fully hardened.

❍ 12. Apply 30-minute epoxy to all joining surfaces of the fin.

Insert the fin and wipe away excess epoxy. Use a 90-degree

triangle to check that the fin is vertical. If necessary, use

masking tape to pull the tip of the fin to one side or other of the

stab until it is vertical. Do not disturb the model until the epoxy

has fully hardened.

When the epoxy has fully hardened, make sure the rudder

and elevator are in the proper position with all the hinges

properly installed. Place six drops of thin CA on both sides

of each hinge location. Let the CA cure completely. Do not

use activator. Pull on each control surface to make sure it

is glued properly and securely.
