RE: First Scratch Build
Mclina
You might want to check out the ugly stick plans that are at the bottom of [link=http://plans.rcmodell.hu/plansport.html]this[/link] page. Jason Niemier (aka Sticktickler on RCU) redrew these adding a nice wing hold-down design and new airfoil. This is a .60 sized plane, but he's flown it with a .48 MDS. I have scratch built this plane and can tell you it's a great flying plane (can't mess up a Stick). Also, Jason has some YouTube videos of this plane if you're interested. [link=http://www.youtube.com/watch?v=mqxakYJ8LLI]Here's[/link] one if you're interested. He also has one that describes the changes he made to the original plan.
Good luck!
