I’m constantly on the lookout for interesting and simple airplane designs. This design from foamflyer is interesting in a couple of different ways. First of all, it’s made from cheap dollar tree foamboard, which is nice. It has an overall pleasing shape with a nice KFm3 style airfoil, constructed a bit differently than the one that I made as a test recently. It’s a pusher prop configuration (which might be nice for FPV/video) and most interestingly, it has just a single aileron. I like it!

The build log appears on this page on the rcgroups forums, and includes lots of build details. Really nice. He’s also got a terrific website chock full of two hundred planes that he’s constructed. Great stuff.

Addendum: The lack of dihedral may make this a less than ideal trainer aircraft, but one of the commenters constructed a similar airplane with a polyhedral wing to add dihedral, and used a rudder-elevator setup instead of the single aileron (my guess is the single aileron doesn’t work as well with the dihedral in place). Also worth looking into!
