RUDDER CONSTRUCTION
.....
The rudder construction is very similar to the aileron construction
that you have already completed. Re-read the AILERON CONSTRUCTION section
before proceeding further.
.....
Unlike the aileron, the rudder is a tapered chord, symmetrical
surface.
.....
Begin by finding CS21, which is a 27" length of 1" O.D. x 0.035" wall
2024T3 aluminum tubing. You have already hot wired the rudder foam core,
so gather that piece also. The rudder foam core should be trimmed to 27"
length.
.....
Basically, you will join CS21 to the rudder foam core; sand the
joints to remove bumps and joqgles; layup the bottom skin; layup the top
skin; and, finally, trim the trailing edge (T.E.) after installation on
the vertical fin.
.....
The lamination schedule on the rudder is 2 UNI on either side at 45°
to the T.E., just like the aileron. Measure the rudder foam core and cut
the UNI cloth to the proper size. Follow the AILERON CONSTRUCTION
procedures to join CS21 and the rudder foam core, as well as to do the
lamination. Because you have already performed the sequences once; guard
against becoming sloppy. The finished rudder should look much better than
the first aileron because of the practice you have had.
