Your interpretation is correct but here's more than you probably want to Know.
The original Long eze plans had a specific number of plys and length of each for the spar caps. Very shortly after people started building it was found that the manufacturer was making the roving thinner than the original batch Rutan used. People were getting spar caps that were under size. That is why the change came out to specify that the trough layup should be filled using as much as was required to fill it to the top
The design strength of the spar is determined using a specific cross section of spar cap at any given station line. So what matters is that the trough is filled to the top at all points with the uni glass. Just keep laying in the roving material til it comes up to the top
I am working on my roncz canard. I am to the point of laying up the spar caps. As I read it, the layers of tape are left to my discretion so as to fill the troughs. I know it says that each layer will be approximately 4 to 6 inches shorter than the preceeding layer. Does anyone have anymore guidance than what is in the plans?
