Hey Ron!!! I liked your website...nice pics of the plane. I do have a few Q's though... WHen you kept the sides 90deg, how much area does that subtract from the stub wing area and how much does it affect lift? Also, I notice that on your foam/carbon fiber fuselage, you used what appears to be the stock locations and numbers of crossmembers, ect. I noticed that others have used different patterns and methods, ie: Barrios...how does using the foam/CF in the manner you did affect strength since there is not plywood to act as a gusset? I also noticed that you installed it one panel at a time on the sides...does this affect strength? Sorry to be long winded.... Hi Scott, As for the stub wing question, I think the lift loss is negligble. I lost more stub wing to the fact that I widened the fuse 6" than I did with the 90 construction. I am not worried about it in the least. My stub wings are about 20 inches. I did not want to reinvent the wheel, so I kept the fuselage trusses the same. The Carbon grafite skin is 5 times as strong as Eduard Barrios e glass. You could stand on the tail of my fuselage and it would not give a bit. It is very strong. The main reason I did it that way was to make it quiet. It is about the same weight as plywood. I just wanted a plane that was quiet, comfortable, and easy to make. That is why I did what I did. BTW the foam pieces are put in one at a time. They are just there to hold up the carbon and keep the shape. They offer little structural strength. The cabron is laid up in long pieces over many of the panels, overlapping by at least 2". I might lay up another layer of deck cloth to finish the fuse. I haven't decided on that yet though.
