So, after work this week I thought I should make a slow flier and wondered what plans I would use...then it hit me, "Hey! Why not a tandem wing!" This design is based off of Delanne's designs and images I saw of 1950's free flight Delanne style models. It's a boxy, classic FT Style design, and when I threw it up today the maiden went surprisingly well (though the initial landing skid mount folded on the first landing). I'm not sure it's indoor flying slow, but it can go fairly slow. It is easy to handle and pretty forgiving. Like the other tandem wings it doesn't really stall. If anyone tries it, let me know what you think.
The curve in the fuselage side make doing a "B" fold possible but a waste of foam board, so I built the fuselage in separate pieces. However, you could do a FT style "B" fold fuselage if you joined the two fuselage side halves to the rear deck piece while laying out your plan. That would take up most of a sheet of foam board all on it's own which I thought was not efficient. Mine doesn't have the interior brace, which I added to the plans to help square up the fuselage. When I build another one, I'll use the interior brace and the rear deck brace to help square the fuselage.
Here is Version 1.5 of the plan.
