This weekend past, I picked up this plane and showed it to a friend just getting into the hobby. It was funny recounting the flop, but it was sad, to not finish it with a success. Today, I read a forum thread "foam russia with love" and it reminded me of this thread. I remember really liking the various design elements in this. I re-read it and realized there was one thing I didn't try.
The idea was to build a larger C-pack sized version to see if I could hone in on a flyable version.
So I took a moment to up-size the plans - Viola!
When I have a moment, I might possibly build this. Not, these plans,don'y include any dihedral and they should have about 2-3°.
