I really do not know how strong the taped spruce spars will be. I always have a tendency to build stronger than necessary. After a long look at the sides that came in the Stinger kit I decided to double with quarter inch ply. It will be interesting to see what mine will weigh. My fuse ready to cover. Started sheeting wings today.

I had planed on a 3.2, but bought a Sig Sun Dancer and it got the 3.2. I hope the 2.4 will be enough. I really hate to purchase a new engine at this time. I will try to post more pictures tomorrow.
