Rob Edmonds has a kit at http://members.aol.com/RobEdmonds/RC.html that
is designed for beginners.
Rob is quite close to releasing a follow-on kit for more advanced
flyers. I've flown the test version and it is very nice!
http://www.squirrel-works.com/catalog/megabaron/megabaron.html will have
the R/C conversion instructions posted "soon." And there are a bunch of
other kits that people have converted.
http://www.randrmodelaircraft.com/ is for advanced flyers.
And you can still find the Estes kits but I see a lot of complaints that
those are very fragile.
