❏ 23. Cut the fin leading edge from the 1/4"x 3/4"x
30"[6.4 x 19 x 760mm] balsa stick, then glue it into position. Save the remainder of the stick for the rudder leading edge. Sand the top of the fin leading edge even with R6 and sand the sides of the leading edge even with both sides of the fin.
❏ 24. Use a small razor saw to separate the rudder
from the fin. Sand the fin sheeting and rib stubs even with the fin trailing edge and sand the rudder sheeting and the rib stubs even with the rudder sub leading edge.
❏ 25. Cut the rudder leading edge from remainder
of the 1/4"x 3/4"[6.4 x 19mm] balsa stick used for the fin leading edge, then glue it into position. Sand the top, bottom and sides of the rudder leading edge even with the rudder, but do not sand the “V” on the leading edge until instructed to do so. FINISH THE FIN AND RUDDER
❏ 1. Taking accurate measurements, stick T-pins into
the middle of the fin trailing edge near both ends. Place a straightedge against the pins and use a fine-point ballpoint pen to mark a centerline all the way down.
❏ 2. If you have a Great Planes Slot Machine, use it
to cut the hinge slots where shown on the plan on the centerline you marked. If you do not have a Slot Machine, use a #11 hobby blade to cut the hinge slots. Start by making a small slit. Then, working in small increments, go a little deeper moving the blade back and forth. Note that it’s the back of the blade that does the work.
❏ 3. Use the same procedure to mark the centerline
and cut the hinge slots in the rudder.
❏ 4. Cut three 3/4"x 1"[19 x 25mm] hinges from the
CA hinge strip. Snip off the corners so they go in easier. Temporarily join the rudder to the fin with the hinges. Use masking tape to securely hold the rudder to the fin so it will not move.
❏ 5. Cut the fin and rudder tip from a 1/2"x 1"x
24"[13 x 25 x 610mm] balsa stick, then glue them to the top of the fin and rudder. Be certain to leave an approximately 3/32"[2.4mm] gap between the fin and rudder tips.
