I got the Katana50 a few weeks ago, and finally got some time to get around to building. All I can say, is I like the build and construction of the model. However......

To attach the wings, there is both a screw to hold the wing to the fusalage, but also a spring between two eye bolts. My quesiton is how to attach the spring which is located forward of the fiberglass tube and hard to reach?

I took a scrap piece of 4-40 rod and made a curved hook at one end. I then attached the spring to one wing. Take your 4-40 rod and put through the hole in fuse from opposite side and hook the free end of the spring. As you pull wing tight against fuse, also pull the 4-40 rod to pull spring through other side. Then attach the other wing and your all set. Works like a charm.

Yes, I see how this can be done - Thanks.
