RE: foam planes
Lou,
That's quite a tall order. Here's a link to a site that is a bit more intuitive. [link=http://www.rcgroups.com/foamies-scratchbuilt-428/]RC Groups[/link]...I started building my own and saving tons of cash. Even though that link is for scratch builds, there are tons(almost too many) of discussions on what works best (glues, foams, plans, techniques....). If you don't find anything useful they also have a section for store-bought kits that seems to get more responses from members.
Good luck!
