They said it was indestructible.  The top motor mount runs the full length of the fuse.

Hmmm, I may need one of those...

I'd put money on it I could destroy it.  Matter of fact, I guarandamntee it.  Lemme fly it, it'll look like this in one flight and I won even have to work at it!

here is a copy of the plans.  I hope they are the right size

The basic wing is a flat balsa plank with openings cut out on esach side and 1/2 ribs glued top and botton of the plank.  The ribs are split front and back of the spar (1 ea top and bottom)  The wing builds quite light and solid.  The bellcrank is mounted external on the ply section top and bottom.  I hope this explains it.

I like it and tried to print a copy.  Only get left half of page.  It remeinds of the construction of the old Omega combat ships, 1/2A and full size.  I can see the construction is for trying to get a flat wing without warps.  The center sheet is made first and nailed/pinned to the building surface.  Put all the top surface on and flip it over and do the bottom.  If you don't like diamond airfoil, the rib leading edge can be airfoiled when you cut the ribs.  Should fly well as it is.

Thanks I do understand the primary part of the wing build and I can see now how my choice of words was ambiguous.

My question refers to the top and bottom sheeting covering the 4 most inboard ribs once the top and bottom rib halves and the bell crank plywood is in place. I suppose it really isn't of much consequence if the sheeting lifts the covering higher than the ribs in the center.

As far as the .15 size, this all started when I started uo up size a 1/2a White Lightning for a .19.  That took a 145%.  Most .15 size kits are around 38 to 41" span.  This particular model was actually a test of the wing construction.  If it was easy I could use it on a sport scale with a different wing shape.  Just cut the plank to shape and add ribs.
