Flash 3D EPP
The Flash 3D EPP is a great plane for practicing 3D maneuvers,
inverted and knife-edge flight, or just fooling around in the air.
Super maneuverable; hovers great; hard to break; easy to fix using UHU Por (aka Creativ) glue on the foam (also at HL). Guys who have flown a lot of 3D foamies rave
about how this plane flies.
It's available from these sites (prices as of 5/5/2010):

Here's my setup:
Motor: BP A2212-13 Brushless Outrunner
Speed Control: HobbyWing 18A Pentium ESC (BP 18A Brushless ESC would also work)
Battery: Rhino 1050mAh 3S1P 30C LiPo
Servos (4): Futaba S3114
BEC (6V): HobbyWing Switchable U-BEC 3A 5/6V
Low-voltage alarm: HRPoly-X Visual/Audio Lipo Low Voltage Warning Device
(the cheaper Doohan or HobbyKing voltage alarms would also work OK)
Prop: APC 10x5E
Cheaper alternative parts that would also work: HXT900
servos, HobbyKing
SS 18A ESC and Turnigy
BEC.
I found it to be an easy build. The ailerons and elevator are
pre-hinged. Carbon-fiber rods are glued in to reinforce the foam. After
breaking the horizontal stabilizer, I added in a carbon-fiber rod. I
used 6-minute epoxy for most of the build (and thin CA to mount the
carbon-fiber rods and strips).
For the aileron servos, I put in 4-40 blind nuts and used pieces of firm plastic
as mounting straps; Dubro micro XL servo arms, and Dubro mini E/Z connectors. For the elevator and
rudder servo setups, I also used pieces of firm plastic as mounting
straps, and a Dubro micro pull-pull system. Hot glue would also
be a good option for servo mounting.
The stock rudder setup uses CA hinges. After breaking one, I went to
using Dubro Micro E/Z Hinges (#937), which I think work
better with the pull-pull setup.
For the motor mount, the directions call for pushing toothpicks into
the foam and gluing them to the mounting plate. I wanted to be able to
remove the motor via nuts, so I glued 4-40 bolts (with the head cut
off) into carbon-fiber tubes, and glued the tubes into the foam. The
motor-mounting plate then is attached via 4-40 lock nuts.
