Talking about things that doesn't look like it should be able to fly and RC models reminded me of those hydrofoam and stormlaucher flying boats, those really do not look like they would fly, but they apperantly do...

Then there is that dragonfly, but at least that has wings...

Of course, I can't say anything about how well they would scale up...
