Hi everyone,
My name is David Mason. I am an process controls enginner and I live in St. Louis Missouri. I build foam-board airplanes in my basement.
I have built a lot of the Flite Test designs. My latest ones were the Sea Duck and the Edge. I love the Sea Duck and I haven't even had it on water yet.
I have been building FT planes for about 2 and a half years now and I am ready to step into the design world for a new challenge. A few weeks ago I designed and built a twin boom pusher based strongly on Andrew Newton's Depron Spectre. The final product came out relatively nice and after balanced, it flew well and I have taken it out several times. This did nothing but boost my confidence of course. I am now in the process of designing a 2 meter EP Foamboard Sailplane. I have jotted a few ideas down on paper and started testing out some wing ideas.
I will use this thread to document my progress and I welcome all feedback you can provide to me.
Below are the first ideas I wrote down. I knew I wanted it to have a wide wingspan and be made mostly of foam board.
I would like to have the wing be at least two pieces. So I need to find a way to assemble it in the field.
I would like to have a horizontal stabilizer mounted on the top of the vertical.
Im considering adding flaps and spoilers.
My biggest concern at this point is how to reinforce the wings. I have had ideas to use dowels, aluminum, and carbon wing spars but I need to keep the thickness of the wing to a minimum.
The wing chord also needs to be a lot shorter than a standard airplane. So I need to find ways to reduce the chord and thickness while also having a rigid wing that is able to be disassembled.
