Using Gorilla glue I've glued in the landing gear spars and filled in spot on the wing spar where the glue did not foam up enough. This Gorilla glue is great for working with foam as it will seep into gaps and expand to fill the area. It's somewhat water active in that the water makes it foam up a bit more, thus the spray bottle is shown in the picture.

You can see where the landing gear block will mount in the empty carved out space between the two landing gear spars.

The Gorilla glue sands pretty easy. Using a sanding plane and block I leveled the surface for the spars.

Did the same too on the other side.

I then cleaned out the area for the landing gear block and rechecked the fit. Looks good!

Creating the wing skins is not to hard. Just get several sheets of balsa sheeting, butt them together and use tape to keep them butted against each other.

After you've butted enough balsa sheets to cover the wing, flip it over and use thin CA to glue the sheets together. In some cases I use gap filling CA because I had a few areas where the balsa was not completely straight. The gaps were very small and probably could have been left alone.

I repeated the process for the top and bottom wing skins and here you see the final outcome. To achieve this you need to measure and cut the balsa sheet skin to shape leaving at least 1/2" over hang on the sides and leading edge.

Here is a side view of the wing sheeting.

To make the second set of wing skins for the other wing I traced the top side of the first wing skin. I also label each wing skin half so I know which one goes where when it come time to glue them. **NOTE: Remember to flip the first wing skin over so you don't end up cutting two for the same wing.

Everything is traced out and now I will cut out the wing skin.

It's been cut out and now I will do the other side.

Now I can't just trace the previous one because of the way the landing gear block is in the way. So I made my cut out for the block and measured so the next balsa sheet that I would butt joint would be flush along the top of the block.

Well both wings now have wing skins and read to be vacuum bagged.

I just could not resist placing the landing gear wire in to see how the wings look with them.

Normally you have wing shucks, which are the top and bottom shells after hot wire cutting wings. However when I purchased the wing from U Fly Hobbies they did not send the shucks. So I am hoping that the wings will be thick enough not to warp when it comes time to vacuum bag them. I plan to cut out the fiber glass cloth to place over the spars, but under the skins and get ready to vacuum bag the wings.

Stay tune for Session 8 to be posted soon!
