Finished rudders with trim tab and outside items. Sanded them to shape with vertical belt sander and cleaned up by hand.
Completed vertical fins and sheeted one side, will sand balsa end blocks when rudder is joined.
Found, after the fact, that the rear spar on the fin was laser cut 1/8" short in length. I had already glued on the balsa blocks before I realized the error and now it looks like the rudder top will have to be reduced to match the fin. Just shows you have to check EVERY detail before you glue things up. I have to wonder why the spar was cut undersize.
Elevators finished with trim tab and outside items. Sanded them to shape and cleaned up by hand. Much more work here for internal control rods connected to servos located in fuselage below stab. Working out details on controls for rudder and elevator as I do not want control rods or servo arms to show.
Actually set stab and fin on fuselage and I am really beginning to see just how large the model is.
I am happy with the internal web design of both the rudder and elevator as they are very strong and straight. This method took at least 8 to 10 additional hours but I feel it was time well spent.
To be scale the ailerons must also be fabric covered like the rudder and elevators and I am looking at the internal web design for them as well. Initial look at the aileron design shows it maybe difficult to use the internal web method, however I do want the ailerons fabric covered. This ought to be interesting.
