I did a bike ride yesterday and had to mow the lawn this morning, so I didn't get back into the shop until 2 PM today.


Ok, First there's maybe a little more cutting, drilling, shaping and sanding that needs to get done before I can get out the glue. First thing I did was to get out my 5/8" TWB hole saw and put some holes into the elevator (forgot to do that the other day when I did the cambflexers ).



Also used the #1 rib that came with the kit as a template to make a pair of light ply copies. Normally the two 1/16" balsa ribs at the wing center get laminated together in the construction of the wing as a single piece. But I'm not making this wind as a single piece, so those two ribs are not going to be laminated. Therefore I'm substituting light ply to make up for the lack of strength.
The violet tube is the substitute for the plywood dihedral brace (also shown) that would have been glued in place. Most people use brass for this, but I found an alumini(u)m Heli boom that is just as stiff, if not stiffer, and it's also much lighter than brass. Heck, it's even a whole gram lighter than the plywood brace it's replacing.


I had a little trouble with the wing, my fault really; I pinned the rear spar too far back and didn't realize this until everything was pinned in place and the glue had almost dried So I had to remove it, shorten the back end of the ribs while still glued to the rest of the structure, re-notch the spar and re-glue it all back together. As such I was only able to get the bottom half of the left wing done.
