If you are building or have built one of these, you are familiar with the pieces that make up the elevator tips. The tips are built up with six pieces of 1/8 die cut balsa. This consist of two different parts spliced together and stacked three times (Picture 1).

I changed the ends of these parts slightly (picture 2) to adapt to the design changes I made to the elevator and stabilizer (earlier post).

I replaced the middle set of 1/8 balsa with three newly shaped pieces of 1/16 birch plywood spliced. (picture 3). The black lines on the plywood show were the splice for the ply is.

The intent here is: 1-to offset the spliced joints for strength… 2- the plywood through the center line like this should provide for a little more resistance to hanger rash… 3rd- more a side effect versus intended it will thin out the tips that 1/16 of an inch. Of coarse they will be feathered in to the 3/8 leading edge and the 3/16 trailing edge.
