Every required piece of foam and plywood is drawn in the plan but there are no building instructions. And sometimes you need two pieces like for the winglets and the canopy side but only one piece is drawn. That's what I meant with "But of course there are a lot of unknown details...".
Basically you'll find the parts you need on the right side of the plan and on the lower left side are the three layers of the wing and the fuselage shown.
Have a look at the pictures in this post
about how to fold tho bottom and the top wing layer.
I haven't had the time yet to do a build log or to improve the plan. In the meantime just ask me for details.
