LexxJet Rocket Assembly

1. Using 400 grit sandpaper, ﬁne sand the

balsa sheets before removing the ﬁns. Care-

fully remove all the pieces from the balsa

sheet by freeing the edges with a sharp hobby

knife. Save the scrap wood for step 4.

2. Group the like ﬁns together, and gently

sand the edges as shown in the illustration.

3. Glue the leading edge of the wing onto

the main wing using wood glue.

4. Glue the horizontal tail ﬁns together. The

ends are propped up 1/8 inch to give the cor-

rect amount of dihedral. A piece of scrap balsa

wood under each tip can be used as a spacer.

5. When the glue is dry on the ﬁns, you can

apply sanding sealer to the surfaces of all the

balsa pieces to smooth out the wood. Coat

both sides at the same time to minimize the

chances of the ﬁns warping. Do not allow the

sanding sealer to get on the root edges of the

ﬁns. This could prevent the ﬁns from bonding

well to the body tube when they are glued on

later. Set them aside to dry completely. When

they are dry, sand the sealer smooth until you

get a desirable surface ﬁnish. You may need

to repeat this step several times depending on

the level of quality you wish to achieve.

6. Using a razor saw, carefully cut off the

tip on one of the nose cones. The location of

the cut is on the forward side of the raised

bead nearest the tip of the nose cone. You can

discard the tip of the nose. Clean up the end

with sandpaper to make the edge smooth and

free of rough plastic.

7. Using a hobby knife, make a deep

score in the plastic along the groove line on

the shoulder of the piece trimmed in step 6.

After going all the way around the perimeter

with the knife, gently press on the score line

you made. This will cause the plastic to crack

and separate the back half. Discard the rear

portion.
