with thin CA glue, then re-tap the threads after
the glue has completely hardened.

10. Cut approximately 1" off the threaded

portion of the 1 /4-20 x 2" nylon wing bolts. Bolt

the wing onto the fuselage.

2. Temporarily slide the fin into place. Check the

fit of the parts. The bottom edge of the fin should rest
on the stab.

two inch portion of the stab/fuse junction only. Re-

move the fin. Thoroughly glue the forward two
inches of the stab to the fuselage from the inside
(through the fin slot) and outside (do not go all the
way back to the aft end of the fuse until you are told

to). Be sure to also glue the stab to former F-5.

5. Apply a generous bead of medium CA to the

bottom edge of the fin and to the fin slot in F-5. Slide

the fin into the slot in the fuselage. Check the
alignment to make sure the fin is not leaning. Also
glue the fuse joints at the top corners.

If you are using rubber band on wings, temporarily
slide the dowels into the holes in the fuselage
sides (enlarge the holes in the fuselage with a
round file if the fit is too tight). Align the wing and
attach it with several # 64 rubber bands.

MOUNT THE TAIL SURFACES

1. Slide the horizontal stabilizer (stab) into its slot

in the fuselage. Align the stab by looking down at the

stab reference lines through the fin slot in the upper
aft fuse sheeting. Put a couple of marks on the stab
outside the fuselage sides for reference after the
vertical fin (fin) is installed. (The photo for this step

is at the top of the next column)

3. Sight the alignment of the fin and stab from the

front and back of the model with reference to the
wing. Also sight the fin and stab from the top to check
alignment. Make adjustments to the fuse slots if

necessary so the surfaces are not twisted or skewed.

sure to flip the fuselage over and glue all stab, fin

post, and fuselage joints from underneath.
