Hi Ed,
No I asked because I have no idea what he meant by this. It is a plane that is built using a reversed delta as the main wing and fuselage. It is an oddball design that I am working on, it is in the build and design forum, in a thread called oddball design.
I had switched over to spoilers for roll control thinking due to the low wing loading of my plane I would be better off using that method as opposed to anything that added lift given the low wing loading of the plane 4/5 oz/ft. I have no idea what "apparent wing loading meant" as I replied to him. I am not an aerodynamic engineer and don't know what he meant so hence the question. The person who said it is someone whom has a lot of knowledge, so now he has me worried that I missed something else. Last night I found I may still have a problem with tail volume due to the short tail moment arm.

P.S he may be a neighbor of yours...
