..... The rudder construction is very similar to the aileron construction that you have already completed. Re-read the AILERON CONSTRUCTION section before proÂ¬ceeding 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 trimÂ¬med 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 UNIon either side at 45Â° 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 loqk much better than the first aileron because of the practice you have had.
