Raf,
I've not had one, but a buddy of mine when I lived southern Georgia did. If I remember correctly, his was built up, not foam. It was an unusual aircraft for sure (it was ugly, in my opinion). It flew like a pig with wings, probably because it had so much drag, and it was probably was underpowered, although its owner swore up and down the engine was what the plans called for. All I remember of it is how it lumbered along in the air and then when landing, it would just pancake down onto the ground and bounce like a beach ball. Halarious! I think I'll build one!

Here's a link to a site that sells the plans. [link=http://www.modelaircraft.org/plans92.asp]AMA Plans Listing[/link] Take care!
