Well on the first few steps you have to set up the fusalage siding. I can't figure if the doubler 3/32" ply and 1/32" ply glue over the 3/32" ply that extends across the entire fusalage side (kind of like another backing support). And also, this longer peice of ply - does this need to be trimmed for the wing spacing? My kit is either missing parts or I have to trim the peice.

I guess it kind of confusing if you don't have the kit. I appreciate any input - thanks!
