tph1,

The moments are the same, but the airfoils are thinner and their areas are different. The fuselage has nearly the same volume as Version 3, which is alot. (See planview image)

Wladimir,

I have the ZDZ40 drawn into a side view of the fuse...when I find it, I will post it for you...it looks good even though I probably won't go that route. I have already ammended the plans and 3D model to lower the belly another 3/4" (see 1st image versus the plans image), so the next one will easily accomodate the ZDZ...even the plug cap.
