Sorry for the picture quality, this is what I have so far. the cowling is 10 inches by 2 inches and then I rounded it. the wing is 22 inches (overall wingspan when the plane is finished = 44in). Cord, where the wing meets the fuselage, is 8 inches. the trailing edge is kind of choppy that's because the ruler kept sliding and it didn't matter how much I pushed on the ruler. This was just a test build to see if my idea would work, my thought process was that if I put tabs on the top and bottom of the wing, could I cut the power pack in half and it still work? Well, I got the bottom pieces attached and realized that the airfoil of my wing was the same thickness as the powerpack half, so, I had to go back into Inkscape and double the walls back up and it ended up working. If I get this plane to fly, ill consider posting plans if anyone is interested.

What I plan on doing is running an aluminum spar down half of one wing and half of the other and putting the dihedral in that way, I may consider adding a carbon fiber rod into each wing for strength.

Any comments or advice would be great, questions, ill do my best to answer them, like I said in my first entry this is all new to me, still learning any input helps.

thanks,
Ruttledge James

This is what I have so far as of my wings, I'm going to test build the wing and see if my powerpack setup even works. I'm hoping it does, its just a flite test swappable cut in half both height wise and lengthwise. I will continue to post updates. Credit to nnicrc for the templates, and to flitetest for the inspiration on building this aircraft.

Im currently trying to design a B-17 Flying fortress out of DTFB (Dollar Tree Foam Board). It is going to have a 44-inch wingspan, and i need to know what size motors to use? And what props, im thinking of using between a 2 and 400 kv motor.. (designed a p51 mustang with a 40 inch wingspan, and it flew fine off one 400). gonna be completely honest i dont really know what im doing and this is all a learning process. just need some advice and opinions.

thanks
