[Note I am not in SD production status at this time, these are first steps. I was tentative posting progress here but I figured the crowd was finite and knowledgeable enough I could treat this as a beta project, a few short kits out to a few sort-of known speed junkies. So I'm officially not in production at the moment just so readers are clear. Working towards it however, and close now instead of "who knows".]

That said, I'm not pushing back. If I can do you one I can do you two. I have some free time this weekend (the car is warming up for the trip to the LHS) and the plan is to crank out a few sets of ply parts, and get some spars trimmed to size. I'm sure I'll be able to make up 10-12 sets - of short kits though, remember. The rest of the wood is off the shelf stuff, might have to poke through the TE/aileron piles a bit.

The original design used 1/4" balsa (on the 45) as the LE. They actually are easier to sheet the LE and stronger if you instead used hard 3/16" balsa or basswood/spruce - this sits flush in the rib cutout and you can then lap the sheeting over the LE, rather than butt joint. Then carve/sand away. The other addition to the stock design is to cut shear webs from 1/16" or 3/32" and fill thebox between the ribs and the LE sheeting - it is a magical transformation in torsional strength and rigidity. Will be changed in the rev 2 manual.
