I have a few other challenges that are unique. None of the internal structure will be the same.
My plan is to keep the basic outline and moment arms the same.
The main fuselage structure, the tail surfaces,Β*and some of the wingΒ*will be built from expanded PVC foam, AKA Β*''Klegecell.'' It requires a lot of thought and planning to get it to work on aircraft. It has no grain and is not very rigid. It is also heavier than balsa or lite ply.
This is my second ''big'' aircraft that will use it. The wing loading will be about one-third heavier than theΒ*kits of this size.
I completed the lofting of the fuselage side and topΒ*and haveΒ*marked theΒ*firewall andΒ*bulkhead locations using the TLAR method.Β*
The KlegecellΒ*fuselage sides will be skinned with 1/16'' balsa. Now I need to determine if I need to bother with lightning holes at this point to meet my design weight goal of 15 lbs.
For those of you who never saw this plane, here is the picture from the magazine:
