top of the fin. Use a razor plane and a sanding
block to do the initial shaping of the tip. Final
shaping should be done later, with the fin taped to

LE’s together with medium CA. Even up the

LE. Draw two parallel lines 1/16" away from both
sides of the centerline.
3. Align the die-cut 3/32" balsa Rudder Plate
(RP) over the plans and mark the “Rib” locations
on both sides of the rudder plate. (See the photo

4. Hold the Rudder Plate centered on the
rudder LE. Apply thin CA to the joint.

Rudder Tips to both sides of the top of the
rudder plate.
6. Glue the two 1/2" thick shaped balsa
Rudder Bases to both sides of the bottom of the
rudder plate.
7. Cut “ribs” from the 3/32" x 1/2" x 30"
balsa sticks and glue them onto both sides of the
rudder at the locations you previously marked.
8. Refer to the photos and the cross sections
