Chapter 20: Winglets and Rudders


Step 6: Lower Winglet Attach

I was going to leave the lower winglets off, but Nat convinced me to put them on.  Since I had already cut my rudders out, I wasn't going to go back and micro on the part of the lower winglet that makes up the bottom of the plans-built rudder.  So I elected to use a smaller (as in shorter) lower winglet.  Mine are about 60% the size of the plans version, so they are not per plans.  I also left off that annoying triangle on the rudder's trailing edge.  I once asked Burt Rutan about the aerodynamic significance of it.  He replied there's nothing aerodynamic about it.  He did it because he thought it looked cool.  True story!
