THIS RUDDER HORN FAILED. GO TO THE LOG ENTRY ON NOVEMBER 27, 2019 TO LEARN WHY.
I did some rough weight calculations and decided to go for the lighter option for the rudder horn which I made the same way as the elevator horn. It is complete at 54 grams. The plans aluminium one was 70 grams and whilst it was before lightening holes it also doesn't have the 1/2" x 1/2" support rails attached. I am waiting on a new delivery of materials so will actually build the aluminium rudder horn purely for the weight comparison.
