RE: Smaller versions of kits
As Bruce said, the desired position for the CG should be the same no matter how big the plane is. If the smaller version of the plane does not have the CG in the proper place then you'll have to make adjustments to get it in the proper position.
Posting pictures of scratch-built planes is WAY above the level of the Beginner's forum. If you would like to have member post pictures of their scratch built planes I suggest that you post a thread in the [link=http://www.rcuniverse.com/forum/forumid_174/tt.htm]Scratch Build forum[/link] and ask them to post pictures.
