RE: Vintage EUREKA GRUMMAN SA-16A ALBATROSS MODEL PLANE
Well there is an engine mount detail at the nacelle
Maybe you can post some close ups of the wings and tail on the plans, or post those pics to photo bucket so we can see them larger
It almost looks like the elevator is the only hinged surface, then what is that detail at the wing tip? that makes me thing it a control line plane at first glance
