Mount the Stabilizer & Fin

❏

1. Using a sharp hobby knife, remove the covering from

the stabilizer slot at the aft end of the fuselage. Also remove

the temporary balsa block.

❏

2. Mark the center of the TE of the stabilizer. Insert the

stabilizer into the slot.

❏

3. Stick a T-pin into the center of the top of the firewall. Tie

a small loop in one end of a 900mm piece of non-elastic

string such as K&S #801 Kevlar thread. Slip the loop in the

string over the T-pin.

❏

4. Fold a piece of masking tape over the other end of the

string and draw an arrow on it. With the stab centered on the

fuselage and the TE of the stabilizer flush with the aft end of

the fuse, slide the tape along the string and align the arrow

with one tip of the stab. Swing the string over to the same

position at the other end of the stab. If the arrow doesn't

align with the tip, adjust the stab and the arrow slightly and

check both tips again. Adjust the stab until the stabilizer tips

and the TE are centered.

❏

5. View the stab from approximately 3m behind the plane.

Check that the stab is parallel with the wing. If it is not, lightly

sand the stab saddle until the stab is parallel with the wing.

❏

6. Use a fine-point felt-tip pen to mark the outline of the

fuselage onto the bottom and top of the stab.

❏

7. Remove the stab from the fuselage. Use a sharp #11

hobby knife or the " Expert Tip" that follows to cut the

covering from the stab just inside the lines you marked. Use

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

wood will weaken the stab and it may break in flight.
