Constructing the fin....

Using CAD I redrew the rib and increased the number by one. This gave closer spacing. I also covered the fin with 3/32 balsa and went with a scale hinge for the rudder to reduce servo loads. I also "fatten up" toward the leading edge of the base of the fin so it doesn't have that starved horse look or the need for a lot of filler. Then the tail and fin were attached to the fuselage with a lot of measuring, shimming, adjusting, more measuring,etc. And now onto the rudder! Total weight so far is just under six pounds.
