OK, I found/downloaded the plans, but was hoping there would be a bit more information. I haven't looked at arrows for a long time, but I remember there being different lengths and shaft thicknesses. Was hoping to know for sure which specific type to get. Was also hoping for some guidance of spacing for the general area that each of the 3d printed parts would attach to something like "The wing starts at 6 inches from nose". I'm grateful for a free plan as a FTCA member, but it seems like I will need a little additional information to be able to complete this project.
