So, the Tiffie first. The original elevators were quite heavy, and have been re-hinged many times, making a mess of the tailplane too. A quick 10 minutes later with some 3/32nd balsa, and I've got the core of them laid out and drying. Thicker blocks are there for Robart heavy duty pin hinges.
Then added the top skins with wood glue. Their is a false LE on these of 1/8th inch balsa, which will have half inch balsa glued on the front of it for shape and strength.
Everything shaped here, along with a block balsa tip, LE's shaped, hinges added. Much smarter, less wavy, and much lighter. Next!
