Foam question. In the early pages, it was said you are using blue foam? Blue is by Dow, pink by Owens-Corning, both polystyrene. Just wondering if you have tried 3M 78. Its made just for polystyrene foams. Has a built in 3- width spray. I used it on laminating the pieces for a plug. Works great. About $10.00 here.

What wing loading are you expecting? I suppose the first question should be what is your expected/hoped for AUW?

WOW!....now that is a big plane. I had thought about building a foam plane at one time but I don't believe I have the talent you have. I did construct some foam intake (cheek)tube for a plane and I used Liquid Sheeting to cover the foam........worked great. The Sheeting is a liquid which you mix in two parts and then brush onto the foam. The sheeting is self leveling so it smooths out really well on the surface and is fairly light weight. Once dry it can be painted. WOW Planes stocks the Liquid Sheeting.

I hope to be 25 pounds AUW, Brent I think is shooting for 20 pounds.

Root chord is 31" tip chord is 9" so 40 devide by two = 20 so 20" is the average chord. Wing span is 81" I am a little fuzzy on how to figure it from here, I think it's somthing like average chord x wing span will get the wing area then devide by the weight of the plane or somthing like that, sorry..I realy should get my head around the numbers a little more

Got side tracked a bit and started doodling around with a seat. OK back to work on the fues again. I added the air vents on top of the rear fues and did a little blending

Naw ..it's 1" on the turttle deck also. It was just thinned quit a bit in the rounding process.

From your pics it dos not look rounded too much but it could be the pic, Well if it's a tad too round you could do a spackle build up in the effected area or maybe a 3mm depron build up if it's off by allot but looks pretty good from the pics

81x20=1620 sq in divided 144=11.25 sq feet. 25 lbs x 16 oz = 400 ozs. 400 oz / 11.25 sq ft = 35.5 oz/sqft

If I've done my arithmetic correctly, you're looking at about 35.5 oz/sq ft.

Just for fun I put my old 81" long F-4 fues next to the 38. I had to chuckle a bit, the T-38 canopy is as big as the main body of the F-4.

Also the Callie graphics look great, she did an exellant job on them
