I'm putting together this Pica P-51B ART that I got recently. It is a
fully sheeted plane that comes just as you see it out of the box.
They prime it and can be covered or painted. Will take up to a .26
size engine. I also had a OS .20 laying around and this is what it
will go in. It is a combat scale 1/12 with a 40" wingspan. I'm not
using the gear that it comes with, but will hand launch and belly
it in. Pica has this and many more combat warbirds at:

By just dropping in your engine and radio gear, makes for a quick
builder, although the cowl takes some carving out to fit the engine
and such.
